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 the adults. Begin treatment with Bifen IT or Bifen LP of the infested area towards the end of April or 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

  • 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.
  • Contains the active ingredient bifenthrin 7.9%
  • Bifen IT is a 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

Additional Information

Pro Tips Many customers use Bifen IT for mosquito control in their back yards. 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 measure device. The tip and measure makes life easier when mixing.

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!.

An excellent product
I've been using this product for some time
I've had friends note that we don't have bugs. I use it in my restaruants, apartment buildings and at home and the lake property. I highly recommend bifen I/T

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.
Review by VJ / (Posted on 7/27/2015)
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!!!!!!!!!

I applied 3 weeks ago and I haven't gotten a mosquito bite since. Dosage directions are a little difficult to understand.

Bifen IT works great
By far the best product I have used for taking care of crickets, scorpions, mosquitos and ants. Plus it last about 3 months in between treatments and is far less expensive than similar products but works even better. I highly recommend it !

Clover Mites Gone in 2 days!
I've had clover mites all over the patio and after reading reviews of Bifen IT. I sprayed one application and noticed some clover mites still around the day after but have not seen one in the 30 days since!
Highly recommend this!

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.
Review by Jim / (Posted on 5/22/2015)
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.

Review by Hope / (Posted on 5/11/2015)
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!
Review by Creatress / (Posted on 4/27/2015)
Best for interior ants, bugs, etc...
This product mixed according to recommendations is hard to beat for price and ease of use. I spray the premises about 3 times a year and have had incredible results. Thanks BIFEN!
Review by MAL / (Posted on 4/21/2015)
Good stuff
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.
Review by Skip / (Posted on 9/22/2014)
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!
Review by NanaSJV / (Posted on 9/19/2014)
Does the job
We get scorpions coming down from the adjacent mountain and Bifen IT takes care of the problem plus any other unwanted bugs. Spring, mid summer and late fall seems to do the trick. DYOPC had fast service and reasonable price.

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.
Review by Bronco John / (Posted on 9/10/2014)

Works as Advertised
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.
This stuff is great!

Best Insecticide
Was recommended by DIY associate when I was in Atlanta, it is a great product, easy to use, no odor and very broad spectrum.
Much better than those I have used in the past

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.

Great product
I have used this around the foundation of my house to keep the black widow spiders away from getting in the house. It works well!

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...

great product
I have been using this product for years. It's great for residential & commercial pest control use. You can't beat the price.

pretty good stuff
I have been trying to get rid of White Flies for a year or more. Used it in a pump sprayer. Day two still seemed to have white flies nesting in the grass. Waited for seven days and resprayed. Two weeks later, seems like the the white flies are gone. So is every other insect.

Best I've used
I have a cabin in northern Minnesota, this is the worst year in 30yrs of going there and having to deal with ticks and mosquitos. I sprayed once with Bifen last week and have yet to see a tick or mosquito. Works great.

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...

I have used this product this spring and summer to kill fire ants in the large yard and in a mowed field next to me.Guess what? NO MORE FIRE ANTS AT ALL!!!
Review by JOHN / (Posted on 6/27/2013)
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.
Review by Miles / (Posted on 2/4/2013)
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.
Review by Okieman / (Posted on 1/31/2013)
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.
