Bifen IT Insecticide

Walt Cline - Pest Control Professional Pro Tip: "

Many customers use Bifen IT for mosquito control in their backyards. Mosquitoes feed on plant juices. You find them on the leaves of plants, bushes, and trees. Try to spray the underside of the leaves. Remember that Bifen IT is non-selective and will kill the good guys such as bees and butterflies so avoid spraying any flowering parts because that is where the bees go. We need to save the bees!!! The 3/4 gal size is the best value, but consider the one gal container because it has a tip and measurement device. The tip and measure makes life easier when mixing. We recommend using a surfactant such as Alligare Surface to get better coverage on the surface of foliage.

Bifen IT - Various Applications & Popular Choice

Bifen IT is a top-rated insecticide for killing Mosquitoes, Fleas, and Ticks. It is also a successful insecticide for killing White Files on ornamental plants. As a synthetic pyrethroid, Bifen IT is a low odor chemical and may be used inside or outside. It is mostly used outside around the perimeter and in yards for insects such as mosquitoes, fleas, and ticks, but it is labeled for use against many other insects as well.

Bifen IT is a product that does not break down easily with rain once it bonds to the surface. Bifen IT is a clear substance and leaves no stain on painted surfaces.

  • Mosquito and Tick Control
    Bifen IT is a popular choice for mosquito and tick control. Spray the lawns and vegetation with Bifen IT for mosquito and tick control. Mix 1/2 - 2 ounces per gallon; use 1-3 gallons per 1,000 square feet. The amount depends on the density of vegetation. Since Mosquitoes and Ticks like to habitat in dense foliage and shrubs, don't forget to spray the vegetation as well as the lawn. Repeat this application monthly.
  • Mole Cricket Control
    The nymphs of mole crickets cause damage in your grass during the summer months. The mole cricket nymph looks like an adult but is wingless. The nymphs are easier to kill than adults. Begin treatment with Bifen IT or Bifen LP of the infested area towards the end of April or the beginning of May in the Southern coastal states. Use Bifen towards the end of May for the Carolina coastal areas. Timing is important for mole crickets since the immature stages of the Mole Crickets do the most damage.
  • Flea Control
    Use Bifen IT for flea control outside. Mix 1 oz per 2-4 gallons of water per 1,000 square feet of outside surface area to kill adult fleas and flea larvae. If larvae is present, use a higher volume of water to penetrate the soil.

Top Features

  • Does not break down easily with rain once it bonds to the surface.
  • Clear substance and leaves no stain on painted surfaces.
  • Contains the active ingredient bifenthrin 7.9%
  • Multi-purpose insecticide that is water-based and contains no alpha cyano group.
  • 75 different pests such as spiders, mosquitoes, cockroaches, ticks, fleas, pillbugs, chinch bugs, earwigs, millipedes and termites
  • You can apply Bifen IT to a large perimeter area.
  • There is no problem of compatibility with other products such as herbicides, insecticides, fungicides, and fertilizers.

Other Bifen Products

  • Bifen LP is a perfect choice for outside flea control since it lasts longer than the Bifen IT. One 25 lb bag of Bifen LP covers 5,000 - 10,0000 square feet. Use 25 lbs over 5,000 square feet for current flea infestations; use less for ongoing maintenance or prevention. One drawback of insecticide granules is that it doesn't work as quickly as the Bifen IT. Some people will use Bifen IT monthly outside to treat not only the fleas but mosquitoes and ticks, as well.
  • Bifen XTS- Contains 25.1% bifenthrin

Great Product
I live in SWF. I purchased a house that was inundated with cockroaches. I mixed 1 ounce per 1 gallon of water. Sprayed 4 gallons around the perimeter of the house. 3 feet up the wall 3 feet out on the ground. Sprayed in the walls where I had a open like around plumbing. Than sealed all around the plumbing where it went into the wall with caulk. Been here a year I spray religiously every 3 months and haven't seen any bugs of any kind since. Great product.

Awesome Product
I live in the suburbs of Atlanta (HOT-Lanta). The mosquitoes will carry you away during the summer. I couldn't stay outside for more than a minute without getting bites everywhere.

A few years ago I purchased a Stihl brand backpack gas sprayer along with Bifin - recommended from a friend that runs a pest control company. Best advice I ever had!

After a treatment, I can stay outside for hours and hours without a single bite. It seems to last 2-3 weeks on average, then the mosquitoes will slowly start coming back. Simply spray the yard again. Seems to cut the ant population down to almost nothing as well.

This works so well, I even bought another backpack gas sprayer and gallon on Bifin to leave at our beach house in Florida. Really knocks down all the mosquitoes. We still get some nats (they don't bite, merely fly in your face). Haven't figured out why they aren't dying. Doesn't matter, they don't bite.

All I can say is that if you are using this product and still have mosquitoes, you are doing something wrong. Spend the money and get a quality gas powered backpack sprayer. Much more effective than the handheld sprayers.

Five stars!

It works well, but it didn't last long once it rains it is gone.

Awesome stuff
This stuff is AWESOME!! I live near a river and the mosquitos and bugs are horrible. I been using bifen i/t for about a year now and never disappoints. Keeps the house bug free!!
Review by Eric / (Posted on 8/25/2020)
This stuff is the BEST!
We live next to a lake surrounded by swamp and this was the first summer we’ve been able to walk from our house to our cars without being carried away. Let me also add I haven’t seen a single mosquito on our land, I sprayed June 11th and it down poured unexpectedly 4 hours Later, today is August 18th and just started seeing ants and mosquitoes again. I will spray this weekend and be good till spring!
Review by De5troyer_340 / (Posted on 8/18/2020)
Keeps ants and tics under control.
I use it in my yard for ant and tic control. Twice a year seems to do the trick
Review by Oldgoatdj / (Posted on 7/9/2020)
Works as advertised
Sprayed this stuff all along my house and yard and this stuff really works!!! Haven’t seen one ant or bug with the exception of snails. We definitely have a snail issue and was hoping this stuff would take care of it. Planning on doing another application to see if it will help with the snail issue. Since this product kills what snails eat I’m hoping they move on to another location otherwise I’ll have to buy something that will kill the snails. Overall I’m very happy with the results I have received with this product. Yay!! No more ants or creepy crawlers and I purchased the largest size so I should be set for a long time to guard against these nasty bugs. Why pay for a service when you can save a bundle by doing it yourself!!! Thanks to doyourownpestcontrol for making these products available to the average customer. Hopefully I can get rid of the snails and my home will be totally protected from all these pesky bugs!!
Review by April / (Posted on 6/28/2020)
I have to tell you your product is a life saver.
I have to tell you your product is a life saver. We had a swarm of MILLIONS of grasshoppers in our neighborhood. Entomologists said it was a 15 year cycle. Nothing worked. I went on your website and found Bifen IT. My neighbors are using it too. Works wonderfully and there is a long residual even after watering daily. I cannot thank you enough. To say there were MILLIONS doesn’t really describe it. My pest control came out and was horrified. I had the local paper come out just to show people. The camera man did not want to get out of his car. There have literally eaten there way through 3 blocks of homes.

Thank you again

No luck
Shipping was quick. I used the product twice and it didnt work for us. I ended up having to pay an exterminator to fix our issue. Although it didnt work for us I am willing to use this site again for other post needs.
Review by Lebleu / (Posted on 6/15/2020)
My house is over-ridden with mites - clover or spider I can't tell for sure, but there are millions of them in my yard, home perimeter, etc. They come in through the windows, etc. This product kills EVERY SINGLE bug like creature --- except the mites. It will kill the few that it gets directly sprayed on, but as soon as it dries, millions more come crawling out all over the same spaces I JUST sprayed. Please give us something for MITES!
Review by AJT / (Posted on 6/5/2020)
Very good product
I've been using Bifen for a few years and it works great. I spray for myself and some elderly family members. Works great and the service is great!
Review by Jimmy / (Posted on 5/30/2020)
Best product been using it for years. I have a few friends that have ordered it and they are amazed how great this stuff works.
Best product I have ever used. I have used other company (box name) to do my yard they worked. This stuff works great. Will do what it says. I also spray my yard and trees. This will not destroy or dis color your grass or kill your trees, but will kill the bugs. I used it around the house and inside. Will kill flies and mosquitoes.

Knocks 'em dead
I live in the woods near a big creek. Lots of critters and lots of bugs.
One pest that really LOVES me is chiggers.

I loved 'em back with Bifen.
No more chiggers.
Review by Reel Texan / (Posted on 5/15/2020)
Worth having lasts a long time.
Besides knats I also have ant problems not fire ants but what I call picnic ants. Thankfully they don't bite but can do damage to electrical like AC units and vehicles. Since using this product all critters are kept at bay. Besides working it lasts s LONG time.
More bang for your buck.

We have only use this for ants, but it works great. We are planning to use for other insects because my sister orders this product all of the time and she swears by it.
Review by Talfe / (Posted on 10/1/2019)
Great product; great vendor.
Works very well for mosquito abatement here in GA. I apply it once a week in my yard using a 4 gal. battery-powered backpack sprayer. Probably costs me $6 a month vs. $80 for a pest control company to do it once every 3 weeks. It's a no-brainer as far as I'm concerned.
Review by JML / (Posted on 10/1/2019)
Chiggers Beware!
I have an "all stone" yard. Unfortunately, Chiggers love to live there. I have tried every big box store remedy. I finally did some research and came across Bifen IT. No more bugs of ANY kind! This stuff is GREAT! And it lasts a long time. I spray about every 3 months. Seems to do the trick!
Review by Scott / (Posted on 9/15/2019)
Where have you been all my life???
Up until now, I had tried almost every product available on the shelves of the Home Depot and Lowes. I was being eaten alive in my small yard. Whatever relief those sprays offered, it was temporary at best and I'm talking about only a few hours of relief. I couldn't stand by my hedges to say "Hi" to my neighbors without 5 or 6 mosquitoes landing on each leg.

I don't know how I came across Bifen IT or why I decided to give it a try. Maybe it was the 5 star reviews and the testimonials. All I can say is that I can stroll confidently around my yard in shorts without a single mosquito to bother me. It's been two weeks since the first application and I can still sit on my patio and enjoy sunsets. Now when I visit the home centers and see the insect repellant aisle, I just smile because I won't be wasting my money any more.
Review by Deuterom / (Posted on 9/11/2019)
Great seller / great product
Y’all have a good price and excellent shipping times, so great service too. Bifen IT works. I’ve used it for several years and it smokes the pest service guys I’ve used for mosquitos and I’ve never never had a termite problem in the termite capital of the world, Ga.
Last Wednesday night we got tore up with mosquitoes. Thursday morning I did a quick and small perimeter spray before we left for the weekend. We sat on the patio last night for a couple hours and I don’t think either of us got one bite. But I already new it works!

High quality product
The Bifen IT Insecticide is a great product for use around the home.
Review by Great Purchase / (Posted on 8/21/2019)
It works
Shenandoah Valley, VA. House is wooded with considerable undergrowth in the back and more open in the front. We've only been here 10 months, but mosquitos, biting no-see-ums, gnats, and ticks have been the main pests last fall and this summer. Using a sprayer dedicated to his purpose. I mixed at the higher rate recommended in instructions. Sprayed as directed but it is difficult to spray undersides of leaves in the undergrowth. Have sprayed twice about 3 weeks apart but both times heavy T-storms rolled thru 14-16 hr after spraying. In spite of the rain, it seems to be working and the biting pests are greatly reduced. Unclear how long the effects last, but it appears at least 2-3 weeks. Do not spray areas with flowers and other plants that attract bees and butterflies.
Review by TL / (Posted on 8/5/2019)
Excellent product
Combined Bifen IT with Nylar through a hose end sprayer for yard flea control. After a thorough spraying, & praying, fleas are gone. I would not hesitate to recommend Bifen IT combined with an insect growth regulator & praying to anyone. Thanks for a great product!

No more mosquitos!
Excellent for mosquito and tick control. Sprayed the perimeter of my yard, the yard itself, and the house. Only have a few stray mosquitos. It's lasted for three weeks so far, and that's with over three inches of rainfall!
Review by Derek / (Posted on 7/9/2019)
Excellent product
I purchased to prevent bagworms. It has met expectations. No bagworms this season on the area sprayed. I saw some ants outside my house, checked the label and it works on them too. I sprayed and 30 minutes later I had a small pile of dead ants.

The measuring / dispensing incorporated into the bottle makes measuring super easy and accurate.

I'm gonna buy more before some gubmint bureaucrat figures out this stuff works and bans it.
Review by Martin / (Posted on 6/29/2019)
Deadly and easy to use.
Best product for ants that I've ever used, and love the tip & fill feature, makes it so easy to measure. I highly recommend it.

I have 10 rescue dogs in my huge backyard along with MILLIONS of FLEAS. After 2 weeks of consistent spraying with (Bifen IT), the massive FLEA INVASION is now under control. The price quoted by a PROFESSIONAL EXTERMINATOR was (8X) the cost of this product and a PROFESSIONAL BACKPACK SPRAYER. I could not be happier with the purchase of (Bifen IT).

Best product for mosquito control.
I've been using this product for a couple of years and it's great for pest control. Mosquitos, fire ants, and spiders are gone after a spray and they don't come back for weeks.
Review by Jimmy / (Posted on 11/5/2018)

I have always had good luck with products purchased from "Do It Yourself Pest Control". I like being able to manage my own pest control schedule instead of being forced to be in a contract and have monthly/quarterly visits.

It is your go to chem for bugs!
I live out in the countryside, south west Missouri, and its an hour to any store, or any kind! So needless to say, we try to be self sufficient.
It’s a new house, and I HAD a problem with everything from big, black carpenter ants, to Scorpions! Bifen IT is my go to for ALL my insect problems!! If my wife doesn’t see any bugs, it’s a win win for me! I even use it in the broadcast sprayer on the property to keep the ticks, and the noseeums at bay! This stuff works! Do follow the application charts for your critter you are after!

Review by Doc / (Posted on 6/6/2018)
Excellent product, easy to apply, concise and thorough instructions, better and much much cheaper than calling a contractor. Applied once and then again after a week when I saw just a few of my regulars reemerge(carpenter ants, roaches, earnings). Knocked out everything and still working after weeks. Don't pay an exterminator hundreds per year or even 150.00 per visit. Get the gallon and a pump up sprayer. You'll never call an exterminator again!

I have had remarkable results.

great product
I have used this for the past 4 years to solve a millipede problem. It took one year of following directions to completely eliminate them. I have continued spraying and have no bugs of any type. I spray indoors also as a precaution around my garage and finished basement with no odor issues. This product exceeded all my expectations and the cost is very reasonable. I highly recommend it.

Awesome product!!
This stuff is AWESOME!! Moved from MA to AL and had my first encounter with fire ants, used the Bifen IT to soak the mounds on our 10 acres and those little buggers are toast! Forget all that stuff at the big box stores, this is THE best product on the market!

Best insectecide ever
My wife owns a hair salon sandwiched between two food serving establishments. For 10 years I have sprayed for roaches with every product available. Some were Ok, none good. Then I spied a product with Bifen as the main ingredient. WOW. Not a roach in sight. I spray approximately once a week and I will never use another product. I don't know where the food establishment roaches go, but they don't come to my wife's shop anymore.

We are very satisfied with this product and we use it to spray the lawn for red ants. Amazingly it keeps the mounds in check and we are seeing no fire ants in the lawn. We generally spray about every 4 to 6 months with Bifen. Great product.

Bug Gone
Water bugs...Roaches of all kinds, Termites,...etc. gets'em all. Product was recommended by a local entomologist... Recommended PPE's eye wear, nitrile or latex gloves, ..easy peeasy ... It has good persistence in dry climates but will require re-application after a good rain.. Excellent product ..

An all around great exterior spray product. Knocks out just about any pest and doesn’t break the bank.

This was suggested to me by a commercial pest control professional. It works excellently. Very little odor, good residual protection, and seems to work on all outdoor bugs we have here in Central Michigan.

This product is also an excellent value and I look forward to getting more in the spring.

Product lives up to expectations plus some. I use every 6 months and it controls pests in a very effective manner. I recommend this to my friends and they share my opinion that this is the best insect control on the market. It lasts a long time and is a good repellent.

Bifen IT
This is a great product for fire ant control. I like the how-to videos, support and how fast I receive my order so that I can start my pest control ASAP.
Review by Cindy / (Posted on 10/25/2017)
Twice a year does the trick for me.
Have used Bifen IT for 5+ years. I stick with it because it effectively does the job. I use it especially for fire ant control, but because of its wide spectrum of insect control, it takes care of other pests such as mosquitoes. I'm in south Florida where there is no shortage of bugs, and it is the only insecticide I have to use. I spray my 1 acre+ with most the 3/4 gallon size and do it twice a year. I consistently get excellent service from Do Your Own Pest Control, and they have attractive pricing especially considering the free shipping. That's an all around darn good deal in my book.

Excellent for Ants - Fire ants and Carpenter ants
I've used Bifen IT for approximately 2 years. It has done a great job as a general insecticide perimeter spray for the house and dog kennel. I've been impressed with it's effectiveness on Carpenter ants, just spray the trails they are traveling and they are gone. Stops scorpions and spiders. You will need to study how to avoid killing the good bugs; it is not selective.

Great mosquito control product
I started using Bifen part way through the summer after finding that the garlic spray was only partially effective in controlling mosquitoes. Used as a perimeter spray Bifen has all but eliminated them from our yard. Sprayed initially once per week but have been able to increase time between applications to 3 weeks. Still use the garlic spray in other areas such as flower beds and on the lawn. Very happy with the results.

We use this product in and around our house and outbuildings. It does an excellent job of control all types of bugs and spiders. This year we sprayed around the perimeter of the concrete walkway of our inground pool due to always finding spiders in the pool. It worked! Haven't seen a spider in the pool since. Highly recommend this product!

This stuff is amazing for mosquitos
I live in Florida and the mosquitoes are super bad in the summer, this year they seem worse than ever. I received the email for the mosquito kit and called to get more information. The representative was very helpful and I decided to purchase bifen IT. The results have been nothing short of amazing. We used to not be able to go outside in our yard without using mosquito spray on us. Now we can enjoy our yard again. I will say that when we get a very hard rain I have to spray again within a few days. Bottom line this has been the best purchase I have ever, and I mean ever made for mosquito control. Then you so much for recommending this product!

Works great
Heard about Bifen from a friend. He sprayed his property to reduce the grubs that moles where feeding on while destroying his lawn. He sprayed a light mist over the top and it killed the grubs along with fire ants. I plan on spraying my yard in the early fall for the same grub problem but I've been using it to control fire ants and as a barrier around my house and shop. It stops most anything that crawls or flies.

Review by Bill / (Posted on 7/17/2017)
We had one of the worst years for fleas ever in South Mississippi last year. I had a friend introduce me to Bifen IT. After spraying in and around my home there instant results. When the new eggs hatched roughly a week or two later I sprayed again. Game over! I'm a believer. I now treat my yard for mosquitos and other insects and have seen the difference immediately. Do It Yourself Pest Control makes it easy to take your home and property back!
Review by Randy / (Posted on 7/5/2017)
We live in Mosquito Country and this product has made our back yard enjoyable even during peak mosquito season! I have found it best to use after it rains if that's feasible and either early morn or evening when mosquitoes are most active.
Mix in a hose sprayer bottle and go...you'll be so glad you did!

Clover Mite Infestation
I bought this product as I had, and I say had Clover Mites for years. I was told by one bug company that they would charge me $200 - $300 to come spray and additionally I would probably need more visits than one. I tried this product after finding it in a search for answers. It did the trick! After a couple of days the clover mites were gone. It does recommend a second spraying and I will probably do that as well as precautionary as I had a pretty good infestation of these. I sprayed this all over the foundation and up the walls and door of the house including around the windows that they were coming in to. Thanks so much for a great product.!
Review by Clover Mite Hater / (Posted on 5/17/2017)
This stuff works 100%
We mix 2 oz with a gallon of water and spray the property with it. NO ants or bugs anywhere on our property. We used to see ants crawling on our driveway and on the house and travel trailer. No more. It keeps bugs away for about 4 months. Then we retreat. Fantastic stuff!

This is my second year using Bifen IT. It has stopped ants in their tracks in my yard. I spray once every 3 to 4 months and my ant problems stay gone. I have a field behind me and church near me that these fire ants come from and its amazing how well it works for us. It also kept the fleas and ticks away as well. I have used it on several yards for my neighbors and family and they have all been very impressed on how well it works.

Best I have found!
Bought 20 acres in North Texas. The fire ant mounds are so big the cows shiver looking at them. Sandy loam soil they love. The Bifen IT when mixed 3 to 1 and punching about 6 holes at 15 second per hole in a 24"D x 18"T mound was amazing. Dead mound in 2 days. Some mounds had a few stragglers limping around so they got a second dose. After four weeks I have been watching around the perimeter of the dead mounds to see if they moved. No new mounds have appeared. I highly recommend this stuff and so do the cows.
Review by IHateFireAnts / (Posted on 3/15/2017)

Top rate.I live in a Duplex apt.

I Have 3 dogs. Haven't seen a flea since using. Or spiders.( Live with the dreaded Brown recluse.) I recommend it to everyone. Love that it's safe when dried because of children and pets.

Awesome $ Saving Product(s)
I love DIY! This is my 2nd purchase of their product(s). Several yrs back I had the box elder bugs everywhere. Bifen did the trick, along with other creepy crawlers. I used it every season til it was gone. This time I was being bombarded with stink bugs like everyone else and couldn't suffer thru another winter of sharing my home with them. My daughter was amazed to see a pile of dead stinkers at the front door the next day. The goal is to not have them enter b/f winter. My neighbor used a pest control svc and I looked at his bill. They used the same Bifen-same mix of 1 oz to 1 gal water. It listed they used 4 gals and his bill was $125. My cost was under $2 and used 30 min of my time. AWESOME!
Review by IndianaMary / (Posted on 10/18/2016)
Excellent insecticide
I don't give reviews often and I do so only after using it for a while. This was my second purchase of buying Bifen I/T by the case. First time I treated my mom & dad's 3 acres last year. They had insect problems up the whazoo. After the first treatment, it was insect free for 3 months and we had frequent heavy rain during that time. So I did a second treatment and was good for the rest of the year. I used what was left of the case to treat my house. This year I treated both again and it has lasted about 4 months at my mom & dads. So we are doing a second treatment. Bifen I/T works great and fast. You will see immediate results on most insects and the next day for others. You will also notice misquotes will avoid the areas sprayed. This also does great with ant problems too. Spray the foundation and they won't come back the rest of the year. ☺

Product works great
I used the product for individual treatment of fire ant mounds using a one teaspoon per gallon of water mixture and using a galvanized ground rod to probe and work a hole deep into the mound then saturate the mound pouring the mixture into the hole with a funnel and using from one to four gallons of solution per mound. 100% success rate.

Exceptional, Even in Central Florida
Our area is known for many things, including it's bugs. We moved into our new home and were immediately greeted by scorpions, fire ants, mole crickets, mosquitos, widow spiders and other insects I don't even know the name of. Now they are All Gone. We use Bifen IT indoors, and Bifen XTS outdoors and we couldn't be happier with the results.

Works great for fleas
I sprayed my entire yard (over 1/2 acre) to get control of fleas, mosquitos, and other pest that made time in the yard uncomfortable. I set the sprayer to a mixture of 1 ounce per gallon. The insecticide is thicker than water. So I mixed 8 ounces of Bifen IT with 8 ounces of water and set my hose end sprayer to sprayer 4 tablespoons per gallon. This gave me the proper application rate of 1 ounce per gallon. We have noticed a decline in the insects in our yard. Mosquitoes and fleas are no longer giving us trouble. I recommend this product to my friends. It was well worth the time and effort. Very economical. I will buy again.
Review by MSD / (Posted on 8/22/2016)
Great on fleas
Great product had a terrible flea infestation in our yard, it was to the point of walking 10ft in the yard you would have 3 fleas on you. Mixed as directed and applied around trouble spots and a 10 ft area completely around the house. In 3 days fleas were gone along with fire ants in those areas. It's time to re apply but we have been in those gulf coast storms I'm afraid to put it down with 75% rain everyday in the forecast but I'm fixing to anyway so I'll repost with results

Review by Jay / (Posted on 7/12/2016)
This product works as advertised. When I first built my house in east TN. I had a millipede infestation that was so severe I had to vacuum them up from my finished basement by the hundreds on a daily basis and use my leaf blower to blow them away from the garage door where they were entering. I have used this product for the past 3 years and every year have seen a significant decrease in their numbers. This year there are very few and although I will continue my monthly spraying as a precaution, this product has also kept our house relatively bug free. We live in the mountains on 80 acres of land and this product prevents nearly everything away from the house. It also works well on carpenter bees which had been a problem for our log cabin. Try it and follow the directions: you won't be disappointed.

I have started using Biffin IT when we had a huge problem with box elder bugs. It has been over six years now and I have no bugs in my home at all. I use it every six months and it keeps all insects away from our house and yard. Great for controlling fleas and ticks in your yard as well. I only spray perimeter of house and on bushes and plants my dogs don't eat or chew like grass. Works great.

This product works well. I spray my son's house too, and it stays bug free. This stuff does work on Japanese Beetles, and has saved my cherry trees. I have used Bifen IT for a few years now, and I am happy with it and the company gives super service.
Review by Golden Dragon / (Posted on 5/29/2016)
I bought this because we were getting eaten alive by mosquitoes on our back patio. We also had some ants coming into the house somewhere but I thought that would require something else to get rid of them. I sprayed Bifen IT from a 2 gallon pump sprayer first around the perimeter of our house's foundation then gradually worked my way outward into the yard spraying the grass and the undersides of the leaves on all shrubs and trees, and two days later no mosquitoes and to my surprise no more ants ! Great product for sure just be careful with it. Spray it on a clear day, no wind and wear gloves, googles and a mask to be safe.

I use this in a Stihl blower/sprayer system. It works great but make sure and not over buy. This stuff does have a shelf life after it is opened.

No more Pests
On the advice of my brother-in-law I purchased the Bifen IT Intsecticide. I had a serious ant problem around a previous pluming repair inside of a bathroom wall. I touched the mound and it exploded like a volcano with ants. With product in hand I sprayed the mound. I checked the area 2 days later and no movement. I cleaned the entire area a week later and still no more ants. All repairs are complete and I will continue to treat the area to keep the pests away.
Review by Rhino65 / (Posted on 3/14/2016)
The absolute best
Bifen I T is an awesome product. I n the past we have had a lot of problems with spiders coming inside the house during the fall and winter months. I mixed up a batch and sprayed a three foot wide strip all the way around the outside perimeter of our house and within just a couple of hours any insect that crossed that area was dead. Even after rain and snow the barrier is still intact. The bugs don't stand a chance, even the many different kinds of spiders that live in and around the hedges in my yard. Even if they make it inside, they die before going more than a foot or so inside the house. Best long term insecticide I've ever used.

I spent a small fortune on the various fire ant sprinkle and powder formulas only to come back a few days later and they would still be there. The treatments would turn into a white crust and made my lawn look bad.
Bifen IT was promoted on You Tube from a farmer in Texas. They have more fire ants in Texas than here in the Carolina's so I thought I'd give it a try.
I mixed as directed (probably add a healthy tablespoon more ( I hate these little creatures) and filled my sprayer.
Go up to the mound and spray a direct stream into the center of the mound and count 5 seconds. No need to spray the entire mound. When you come back the following day, to see if there are any new outcrops, your quarter sized hole you left yesterday will keep you from spraying the same hole. After a heavy rain, new mounds can crop up new everyday. You will finally be back in control of you own yard. I'm reading more about his products other uses (mosquitoes and even termites) Respect this stuff! Don't spray around flowering plant you will harm the bees and butterflies. And wash your hands after each use.

Bifen IT is the best product of its type I have ever used.
We've lived in our Florida home for more than 42 years and have battled ants of all types. We received our Bifen IT about 3 weeks ago and immediately mixed the solution and sprayed our lawn. The next day I went out looking for ants. I couldn't find a single one!! Not on the lawn, not on the house, not on our travel trailer and not IN the house (we sprayed inside too). And the best news is that after 3 weeks we STILL can't find an ant on our property. We are totally amazed.

Highly recommended. Would use again if I ever need to!
Easy to use. Used 1 gallon tip and measure. Need to make sure that your Hubbard sprayer has a very fine spray pattern that you can control for even application. Quick knock down and long lasting control.

Best place to go for pest control products
Great product and value delivered as promised. Got rid of spiders around home plus has deterred other pests as well including palmetto bugs
Review by Jeff / (Posted on 10/10/2015)
Good stuff
I use this to "refresh" the termite and bug exclusion barrier around my house in central Florida, and to spray the lawn when I see evidence of chinch bugs or other pests. I use a flat shovel to make a narrow trench along the concrete slab, 10 feet at a time, mix the recommended amount in a 5 gal pail with a hose connected on the bottom, and flood the trench, then move 10 feet to do it again. For the lawn I mix the recommended amount of Bifen in a tow-behind powered sprayer for the area I'm treating, and drive the lawn tractor over the area until the tank is empty. I generally do not use it on plants otherwise because the bees and butterflies are susceptible. Also, it's not approved for use on fruits and vegetables. It seems to have some residual effect - remains effective until there's heavy rain.

I will buy this again.
I bought this after reading the many good reviews. I live in South Florida. My dog and house were infested with ticks. Tiny, the size of the dot on an i. Big mamas full of babies. You name it they were in my house and on my dog. First application was to my yard and all baseboards inside my house. Also bathed my dog. They were still there, everywhere. We were still pulling between 50-75 per day from her. Next application was double strength and I used quite a bit. Bingo. Very few around the house. Still a few on my dog but manageable. I will do one more application this weekend and wipe out all of them, hopefully. I gave this a 4 because it has reduced the tick population drastically but it hasn't eliminated them. But using extra strength worked well.

Bifen IT
I bought some of this product several years ago and it works great. This time I bought 2 of the 3/4 gallon containers. I now use one for my personal home and also one for others. It works great on ant & spider problems. Once I use it the problem goes away quickly and I don't have to worry about these pests for a year or two it seems.
Great product!

Mosquito's are GONE
1st time customer, recommended to Do-It-Yourself Pest Control by a friend. I have had a bad mosquito problem in my yard for several years. Could not bring myself to pay the high prices of service every two weeks for local treatments. After using the Bifen IT once, as recommended on the product instructions and treating my entire yard (bushes, small trees, and grass) avoiding the flowing plants for bee and butterfly health, I have yet to get bitten by a single mosquito. The change is amazing. After 3 weeks, I did a more limited treatment, and I did not even get buzzed getting the spraying done. Thank you for a great product!.

Bifen IT
Very good product. Did what is said it would do. Saw the results over night in the morning with the dead insects about the sprayed area. . I used double the recommended strength just to be sure if was effective. Easy to use and easy to wash out of the sprayer. Got rid of crickets, roaches, and a few other insects I did know that were around. Very happy with the product. I would reorder the product again in a slightly larger portion..3/4 gal probably. Thank you.

Works as good as everyone says it does!!
Extremely happy with this product. Used it to get rid of a tick infestation and it worked amazingly. Only regret is that I didn't buy a bigger bottle. I will be purchasing the 3/4 gal soon so I can reapply in 3 months like one user suggested. Great product! Great price!
Review by Mountain Man / (Posted on 7/19/2015)
Great Product
but I wish the directions were easier to understand. I use a 3 gallon sprayer and it is difficult to know if I have to dosage/spray rate correct, especially since I don't want to over apply. However, this is the second year I have used it and it has solved the mosquito problem in our large farm yard with many bushes that harbor them. Highly recommend it for price/quality.
Review by Walt / (Posted on 7/16/2015)
Looking good
Our primary interest was chiggers and crazy ants in the yard.

Using a broadcast sprayer, I sprayed from the house out about 100' in all directions about two weeks ago. There have been no chiggers and very few ants since. This has been so successful, so far, that I will extend the spraying to include about 3 acres around the house.

Fleas in Yard Are History
My home and yard had a bad flea infestation problem that originally began last fall. Last fall, we purchased an annual service with Terminix BECAUSE of fleas that were brought as a gift from the friendly neighborhood cat. Little did we know that it wasn't enough to no longer pet the cat to prevent more fleas, so when this spring came, the fleas came back. After multiple pest control visits to treat the house, we finally realized that we were bringing them in from, get this, THE DRIVEWAY. Even the pest control woman was shocked that they were getting on her pants when she stepped out of her van, lol. The fleas-tons on them-pitched camp on the concrete driveway, and would hop on us (without our knowledge) when we got out of the car into the house . We didn't even realize that was possible, hence why it took us so long to finally figure out that's what was happening! We were referred to this website to order products to treat our yard, versus spending MORE money for professional yard pesticide treatment. My husband treated the yard and the driveway. After that...NO FLEAS. We still have some PTSD, and I've got some lovely souvenir bite marks from the experience, but this product is a life saver. We will definitely continue to use this for our yard. THANK YOU!!!!!!!!!

Product works great!!!
I paid $500 for summer mosquito control in my yard a couple of years ago. Last year I bought this product and only had to apply it 3 times around my yard and didn't have any mosquitoes all summer (I live in SC). I used a regular home garden hose sprayer with the Bifen IT and it works as well as the foggers that were used by the professionals. I love this product.

Fire aunts GONE!!
Used Bifen IT to get rid of the fire ants in wife's flower bed. Used hand held sprayer to shoot down into ant hill for 10seconds. The next day they dead or completely gone. Very effective product.

had trouble with ants in the home and through out the yard. I use the bifen granules around the home as recommended and go over that with the bifen it liquid as recommended. Works great no ants for months. Also use the bifen it liquid for ant mounds in the yard and field ( approx. 2 acres ) and it works great. best product I have tried.

I've used Bifen IT for several years and recommend it to everyone. We live in a humid, wooded area and can become overwhelmed with mosquitoes and other pests. Bifen IT sprayed about 3 times per year keeps us insect free.
Review by Suzy / (Posted on 4/29/2015)
Bifen IT is the best!
I was told that Bifen IT is the 'Go To' of pest control....and it's the truth! After researching, I purchased it upon seeing two ticks in my RV. I had seen one fire ant as well. After spraying it, I went back into the RV to check things. To my surprise, I found about 30-40 dead fire ants! So, it killed more than I even realized was there. And, I've not seen anymore ticks or anything else either.

I like this product so much, it is the one pest control I will always keep on hand. I like that fact that you just mix what you need, as you need it. And, I've already referred others to the site to buy it as well. Thanks so much, Ken, for your help!

Sprayed all around the exterior of the house and now we have piles of dead ants all along the rear exterior wall where they were making their residence. Got the job done. Getting ready to spray for mosquitoes soon too.
Review by Lydia / (Posted on 4/14/2015)
Industry Standard
Bifen is the industry standard for commercial pest control companies. I have used tons of it over the years. The only insect I hesitate to use it on is scorpions. Go with encapsulated or soluble powders for scorpions along with lots of glue traps. It works on roaches also but for an infestation use baits first then go with a chemical product.. When the temps get to 90 or above the UV rays will break down Bifen quickly. Then you will need to switch to a micro encapsulated product. But for the majority of us Bifen is a real winner.

Works well for Asian Ladybugs
This stuff well to keep my home free of Asian Ladybugs, Harmonia axyridis. I have been using it for about six or seven years. Prior to using it, I was overrun with thousand of these Ladybugs in my home all winter.

I follow the label instructions and spray the entire OUTSIDE of the house starting the first of October and again on the 10th and the 20th and the 30th. I use a 2 gal sprayer and wear a respirator and goggles.

Works great.

I've used this product before in the past and it always works! It kills so many different insect right down to the hard to get pesty ones. As any product be careful when spraying it in your household while using. But I have always sprayed twice a year in the corners of the walls on the floor and other places. This product is useful indoor or out. And it works. Awesome Sauce!

Huge flea problem --- this is working well
Applied strictly according to directions from DIYPC and the manufacturer. Used indoors (with Pivot 10 IGR Concentrate) and outdoors. Much, much less expensive and far more effective than the "retail" stuff that I started with.

Works great !
This product works great in our backyard. We have 3/4 of an acre backyard which is heavily wooded and after spraying there is no sign of mosquitos for at least 2 weeks. We got tired of using the products sold at the local big box garden stores that attach to your hose which were a hassle and results only lasted maybe 3 days. With west nile virus being a threat we are pleased that we have finally found a product that actually works!

Great product and easy to use in the gallon size
I live in central Florida have a few pecan trees that get infested every year with web caterpillars. I can't spray the trees because they are to tall and would not want Bifen landing on me but I do use it in the spring on the ground around the trees to try and limit the number of caterpillars that end up the trees. Also takes care of them when they fall from the trees and plan to lay eggs for next year. Pretty much will take care of any bug that gets in the lawn. I try not to use it to often and a gallon lasts me years.

I used the sprays from the local stores, but they were not effective. I am impressed with the initial treatment, and quite surprised at the low residual odor from inside application such as the garage and bathroom areas.

DIY Pest Control has great service, the product arrived as promised, and they have a great price. I am a satisfied customer, and will purchase other items from them.
Review by Owen / (Posted on 7/31/2014)
This is the real deal...
Look no further for the one product that gets it all done. I have a lake home which requires pest control or they will carry it off. I've tried big box store insecticides with poor results. I bought Bifen IT and my problems are long gone. I spray the house, carport, shed, and boat house 3 times yearly. I have "0" bug issues. My wife freaks out if she sees a spider so that's why I spray 3 times yearly even though I'm certain twice yearly would do it. Forget the sticker shock.. this stuff works.

This is some great stuff!!!
I was in panic mode after buying insect spray at the big chain stores HD and L. It was less than 1 week away from my daughters B-Day, 40+ people coming over for a outside party. I got the Bifen IT and sprayed it the morning of the party. I was hoping for the best and preparing for the worst. So I bought 10 Cutter and Off sprays to be placed around the backyard for people to use. You see my backdoor neighbors have a yard of bamboo and a swimming pool that is deep woods green color, not to mention all of the buckets catching old rain water. Anyhow I saw TWO people spraying themselves with spray and went and asked them if they had gotten bit by mosquito's and they told me No that they just saw all of the spray cans out and they were just making sure they didn't get bit. It has been over a month now and still No mosquito's, we still have flies. By the way I'm on 1.5 acres.

Pleasantly surprised,
Review by Blacynoel / (Posted on 7/3/2014)
Great product
This product does everything it is expected to do. I haven't seen an ant or any other bug anywhere around my home or lanai since using it. I was spraying monthly with a general purpose insecticide which did not last long especially during the rainy season. It's been a couple of months since purchase & using it. I am diluting it at 1 oz per gallon which seems to be sufficient. The product cost is far less that what I was paying the pest control company.

Great product
This is the 5th year that the neighborhood group (4 families) have organized for the spraying of houses and out buildings to handle the spiders, flyers and other creepy crawlies that attempt to invade our lake homes. We spray our places just before Memorial Day and it prevents infestation for the remainder of the summer. WE ALLL LOVE THE PRODUCT! Easy and safe to use with taking when taking proper precautions.
Review by Rog / (Posted on 5/24/2014)
This is my 2nd purchase of this product. It was recommended to use on the ubiquitous fire ant. I have found out this product utilizes the Achilles heel / extensive tunnels of the fire ant to quickly decimate the colony. I use a tapered mechanics pry bar to pierce the ground so the poured solution immediately disperses throughout the colony. Previously I used the granuals ( that go bad ) and the powders because I was looking for something easy. I actually noticed some granuals piled beside the mound by the ants Now I have found the work of mixing & pouring is well worth the effort.

best product to kill fungus gnats
Our indoor houseplants were full of tiny fungus gnats which would leave the pots and fly around the kitchen. Nothing we tried worked until we ordered the BiFen. We sprayed a diluted amount from a sprayer and within a day, all the files were dead, and no more were hatching from the soil in the pots.

Review by Don Fisherman / (Posted on 11/25/2013)
effective treatment
I used the Bifen liquid in addition to Bifen granuales to control a severe flea infestation. The liquid was for a quick knock down while waiting for the granuales to take effect. I cannot say for certain that the Bifen did what I expected as fleas continued to appear for several weeks after treating the yard. In addition to the yard treatment I sprayed inside my home with Home Defense, vacuumed daily, cleaned the dog bedding daily, and treated my outdoor dogs with diatomaceous earth. I did not see any real reduction in fleas until I began treating the indoor dogs with Advantage. For now the flea problem is under control as I have not seen any for several weeks.

On the plus side, the Bifen worked wonderfully at controlling the ants that have been a constant nuisance for the past ten years. I also noticed a reduction in mosquitoes as I included spraying the shrubbery when treating the yard.

Working for indoor tick infestation
Well, a nightmare to say the least. Indoor brown tick infestation. Don't waste money on foggers, worthless. This is commercial grade stuff, so of course use breathing protection. Once they are inside it is a slow process, but thus far the results have been terrific. I put a small amount in a glass to make sure the concentration is string enough, so when I see them creeping up the walls I pick them up and drop them in it. It is for indoor and outdoor use, it will knockdown some immediately, but most I find dead after a bit. These ticks have grown an immunity to "over the counter" concentrations of premethrin, so i strongly suggest start with this. Don't mess around with basic stuff, and be prepared for a months long battle. Great stuff...

Waiting to see on performance
We recently moved from Oregon to western Idaho and have been innundated with a variety of spiders, ants, fleas, and an odity called "clover mite". I'm unsure if we really have clover mites but that's what the pest control technician called the little jumping critters. I'd call them a flea because they "jump" when you try to put your finger on them. Hopefully this Bifen IT (used by the pest technician) does the job and takes care of the pests.

Wouldn't be without Bifen IT
I've used Bifen IT now for a couple of summers and manage to keep all crawling insects away from my home structure. One spray each spring and fall around the foundation and out 6" in the spring seems to do the trick. I also use Bifen IT around base and up 6" on the bare ankles my rose bushes and it seems to keep crawling insects off the roses - including those dreaded ear wigs. Bees and butterflies are never near the base of rose bushes, so I'm comfortable spraying there. Turned over a rock in rock garden to find carpenter ants with probably 20+ young winged queens. I rushed to prepare some Bifen IT and after dousing rock, ants and ant chambers, I'm comfort the carpenter ants have gone to a better place. I also spray base of trees up 2' or so to manage the crawlies that manage to get up into the trees and hatch out winter moths. This stuff works, so be mindful of keeping pets away when wet and know that it also kills beneficial insects, so be prudent. I don't broadcast spray this stuff...

NE texas it did not kill earwigs in or around my house. Tried different potentcies. I even put 2earwigs in a cup with bifen in it. They were still alive 24 hours later. Kills the hell out of everything else though.

Got it for Mosqitoes
I read a lot of places that this stuff is good for mosquitoes. I'm going to try and get a beat on them this year. They get really bad where I live. I don't know how well it will works yet.

I purchased Bifen in the liquid concentrate as well as the granular form. Both are the best products for insect control I have ever used. A year ago I got a hunting camp in Southern Alabama that was so over run with oriental roaches I wouldn't sleep there. It's surrounded by pines and these roaches live in the fallen needles. After one 2' perimeter granular application, I ran out of product, and one liquid interior application the roaches are nearly gone. Anything that finds it's way into the cabin dies within minutes. I find big spiders curled up in the bathroom. Fire ants don't stand a chance against it. I use it in an old apartment building in South Florida and have had wonderful results controlling palmetto bugs, ants and never see spiders. Review by Hunter / (Posted on 1/31/2013)
I live on a lake in Florida and my house is surrounded by large trees. It is a beautiful location. Unfortunately we have huge spider problems. The services I was paying to spray for spiders and other insects were pretty much ineffective and often had to call them back to redo the work more than once. I looked online and found DIYPC and the product Bifen and started spraying myself. The results were instant and I spray about every three months. It only takes about 20 minutes. Also had an infestation of caterpillars eating my oleander bushes. Sprayed those and got rid of the problem (no flowers on the plants when I sprayed so no bees were harmed). One ounce per gallon works great for both.

Stink bug killer
I follow the label and use a hose end sprayer, and then douse my house! Including the roof, particularly the ridge vent. One quart will cover my entire house twice this fall. Keep animals away while wet, but once it's dry, I just sweep up the dead bugs. So far it's lasted for two weeks. I measured the number of dead bugs in a single square foot, 53. if that's the density around the rest of house, I swept up 13,000 dead stink bugs today....and I did it myself.

Excellent spider control
I have used Bifen IT for over 8 years now. Couldn't be happier. Pest control companies come by to try to get my business, and spray my home. I tell them "NO", I do my own at Do It Yourself Pest Control. Spray every other month and you'll have no problems with bugs of any kind bothering you. Not even any spiders get past this stuff. Love it, and it's very safe if you follow the label.

This product gave me my sanity back, I had gotten mites. For 2 weeks straight, I got NO sleep at nights until I started searching the web. I had no idea what the hell was eating me up at night & then after about 4 days of research & nights w/o sleep. I learned it wasn't bed bugs & I'd never hear of mites in my life, but got acquainted with these meanaces real quick. I was almost in a depression until I read a ladies review about Bifen. I ordered it the same night & after spending hundreds of dollars & nothing was working. I figured what could I lose by trying this? IT SAVED MY LIFE!!!!

Works great - thank you Ken and DIYPC!!
Since my elderly mother is allergic to wasp and bee stings (and I hate the loathsome things myself), I needed a product to kill the wasps in our mobile home's eaves by the front door (and elsewhere) so she would not get stung going in and out. I emailed DIYPC and explained how my situation had changed since the last time I ordered from them, needing to get a different product that would work but would also be gentle on our new cat. Ken emailed me back promptly, and since he uses Bifen IT at his home and also has pets, he recommended this product.

It arrived at about 10 in the morning and since I had to go to work at 2, I dropped everything and sprayed then and there. I used it with an attached hose sprayer and went to war with the wasps. The wasps were not happy, to say the least, but only one or two actually almost got to me (I was a man on a mission because you do not mess with my Momma!!). I was a little worried, because while it did have near instant knockdown, sometimes they would keep flying for a second or two. However, the next day the wasps were gone!! That was about 2 weeks ago, and still no wasps. I sprayed heavier than I probably should have, but I did not want to get stung and also wanted to see all their hideouts.

As a bonus, the ants we had tried every home remedy known to man to get rid of are now gone as well!! It took longer for them because they were embedded in the walls, but I soaked our exterior walls top to bottom with this stuff. The number of ants dropped drastically, but a few were still showing up. For the third day in a row now though, no one in my family has seen a single ant. Excellent!!

I don't like chemicals, but I love my mother and it just does not seem right for insects to try and take over if I can do something about it. I will be buying another bottle soon, as I used up all of this bottle on our home and a very small portion of our 5-acre yard, and of course it will be from Ken and DIYPC.

Excellent product that does the job perfectly
We were paying a well known pest control svc to come every other month or so to spray for bugs. I noticed that it was only taking them 5 actual minutes to spray and before I could say, "i'd like to walk around with you, they were done!! My husband just happened to stop and talk to one of the clerks at their Do It yourself store in Atlanta who sold him this product. Well, we've been on the same bottle for the past 2-3 (1 oz or so to one gallon- just follow the directions closely) years and the results have been the same as when we used the expensive company. Only better, because now i take my spray bottle and spray my patio area and around my mailbox. Believe me, once you spray an area, no more pests!!! You will not be sorry on this product. I love it. !!!

A Wonderful Product For Many Pests
I have used this for Mosquito control and for Ladybeetles. Using during the spring and summer for the mosquitos as directed keeps the mosquito population under control for at least 30 days. Bifen IT does not degrade in sunlight like Malathion does. It is deadly for mosquitos!! Use 0.5 oz. -1.0 oz./gallon water and DO NOT retreat for at least one week. Also in the fall ladybeetles will start to come inside the upstairs of our house. I spray the top eves when I see them begin to congregate and usually one application does it!

Great Product and Price!!!
This is a GREAT product to kill every insect in and around your home or outside. We have had terrible spider and grasshopper infestations this year. This will kill quickly and appears to have good residual effect. Do-It-Yourself Pest Control is a wonderful company to deal with and the price on the3\4 gallon is unbeievable. Thanks so much.

Have Used It 3 Years Now
I was surfing the net for something to get rid of scorpions and muddobber wasps and found it here at do it yourself pest control. I have used it for three years now and it takes care of wasps, spiders, scorpions, fleas, ticks, etc. all of which I have living in the country. I usually apply it a couple of times a summer and it is great.

Excellent Product!
Last year I used Bifen IT to treat my lawn for subterranean ‘whatnots’ eating the roots off my grass. Had big brown patches in the grass. Maybe Cinch bugs and Mole Crickets combined. Followed directions and treated 3 times for egg/hatch cycle. Grass now looks great! These treatments also got rid of Fire Ants for a long time even though my neighbor’s lawn is invested with Fire Ants, the ants have not come back! I treated my dog owning neighbor’s lawn and cleared it of ticks. Super product, I'm buying more this year. Easy to apply with water hose and Ortho water hose sprayer.

Great Product that works
I was having a major Mosquito, Spider and insect issue at my new home, and a co worker told me about Bifen IT. I ordered the 4 3/4 gals. and the day I received I sprayed the entire outside of house and yard. During spraying I didn't have one Mosquito bite me and before I counldn't even go in my yard without Mosquito spray on. It has been 6 weeks and still no mosquitos or any type of ant or insect in my yard. My neighbow across the street was swarmed by flying termites one evening and he said to me I don't see them at your place and i told him about Bifen IT and actually gave him some to try and they were gone as soon as he sprayed, I was raised on a farm in the country and have never found a product as good as this. Insects, ant, flies, termites, Mosquitos ALL GONE.
