D-Fense SC will not work well on German roaches. Use a roach bait called Maxforce Impact Roach Bait or Invict Gold Roach Bait, instead.

AS stated the product worked great ! I live on 20 wooded acres we have plenty of Asian lady bugs. My garage is in the basement. With other products I've used i had 250 or more bugs in the garage and stains where i sprayed. With D-Fense I had about 50 bugs get in and they died once inside. No Stains on my house. I sprayed inside and outside.In the living area i sprayed my baseboards. While my wife was out, she never noticed any smell. Shipping was quick, mixing is easy. I will buy again when needed!

excellent product
We use this to get rid of thousands of Lady asian beetles, spiders, and flies. Best product we have found to cover all the bugs we have problems with.
Review by cat / (Posted on 11/17/2015)
It worked!
Had an infestation of elder box bugs. This product took care of the problem very well. They're all gone now.
Review by VJ / (Posted on 11/12/2015)
Appears to work well - lots of dead ladybugs.
I applied this product after ladybugs began entering the house (next year I will apply it before they show up) and although I still get the occasional ladybug in the house, there are loads of dead ones outside! This is my first time using D-Fense SC and it appears to work as stated and was everything this site said it was.

I would recommend you give it a try - just apply it before the swarms show up - in my area that would be early September.

I also found ordering through DIY Pest Control easy and reliable.

5 Stars
I used this product on Asian ladybugs. It absolutely works great! I received the product in two days. So happy with this insecticide!
Review by S.H. / (Posted on 11/5/2015)
I would recommend, very effective product.
Mixed 0.75 oz in 2 gallon sprayer, covered house perimeter and pavers to control fire ants in SW Florida. I had to wait for a dry day to spray due to lots of rainy days. Also sprayed slider doors and pocket doors to control roaches and ants, works great.
Review by SW Florida / (Posted on 10/28/2015)
amazing stuff
This spray worked so well. We noticed a dramatic difference after the first spray. It dried quickly and with no residual smell. In fact, after spraying our whole 3,000 sq ft home, I did not notice a smell or anything that I have experienced with other insecticides. Feel very happy about this purchase and how well it works!

The Best
Have a ongoing problem with Boxelder bugs every year and this product works great. The best so far.
Review by mattmanm3d / (Posted on 10/27/2015)
So far working great
Mixed up product in a 15 gallon sprayer and sprayed the house from top to bottom. Noticed a lot of dead Asian type lady bugs outside of the house. Very few noticed on the inside of the house.
Review by Dave / (Posted on 10/21/2015)
Excellent product
Works well and residual on the walls or floor, We have noticed a lot of dead Japanese beetles. Would recommend the product. Shipping was very quick.
Review by luke / (Posted on 10/8/2015)
Very pleased with the product
Product seemed to work immediately with lasting effects. Happy with the purchase and would recommend to friends. Purchased specifically for the use of silverfish, which resulted in a noticeable decrease in those critters, but also has whipped out an unknown population of several other insects (as evidence by their carcass strewn about outside the perimeter of my house).

Excellent product. Seen results shortly after application

Great product!
Excellent product. My crickets are gone!!
Review by Camy / (Posted on 9/7/2015)
Amazing Product
Bought this for box elder beetles. They were in swarms around my house, mainly my entry ways. This product - after one application, took care of them and every other insect in the area and they have yet to return.

Great product, really glad I purchased it and works great.
Follow the instructions.
Review by Mike / (Posted on 8/20/2015)
Great for Katydids
First year to live in Texas and was over run with Katydids in the 80 post oak trees I have fenced in the yard for my dogs. Sprayed the ground around the trunks and as high up in the trees as possible from standing on the ground. Have picked up over 700 in two weeks. Could not believe how well this product worked!
Review by jhh337 / (Posted on 7/17/2015)
Excellent product.
This is a fantastic product. We had a severe infestation of Boxelder Bugs. On application around the buildings and fence and they are gone. Wonderful on spiders around the foundation. Highly recommend.

Effectiveness of D-Fense SC Insecticide
I have noticed a huge improvement on my spider problem. However I have not found the same effectiveness on ants particularly the large black ants. Lots of neighbors are getting professional spraying because of ants due to the unusual amount of rain we are getting this summer. The product says effective on ants so I am surprised that I can't get rid of the problem.

DIY RESPONSE: Glad to hear you've been successful eradicating the spider problem. For the ants try Taurus SC: http://store.doyourownpestcontrol.com/taurus-sc-insecticide . It has solid reviews against ants and termites.
Review by moondog / (Posted on 7/10/2015)
Creepy spiders gone gone gone
We had to do 4 treatments over 10 days but finally, the spider infestation was eliminated on our lakefront covered porch. The product doesn't smell bad and doesn't leave a visible residue except on windows.

Good product. Glad we bought it.

Great product,,,pill bugs were taking over my fireplace and kitchen,,,it was embarrassing to have company,,,had glue traps all over downstairs,,after a month,,,none from fireplace,,a few here and there from kitchen,,,overall i would recommend to anyone,,,,i lot cheaper than orkin man,,
Review by BIG. E / (Posted on 6/30/2015)
I had crickets around most of the outside of my house as well as around some baseboards and even a few inside the walls. I hate them when I am trying to sleep (or any time really). I used one "dose" in a pressurized sprayer and was able to go around the perimeter of my entire house (2200sf). It took about 3 days to work but in the month since, I have only heard a cricket once or twice. Not sure when I will have to treat again but I have lots left in the small bottle.

Great Product
Your product is great but your customer service is even better!
Review by Diana / (Posted on 6/23/2015)
Highly recommended
This product is amazing. I have thoroughly sprayed the first initial treatment inside & out & that evening I was sweeping dead wood roaches off the floor. 2 weeks later I'm still finding dead bugs everywhere. I didn't have much luck with spider control but any other pest we have, it has zapped them!!!

Works Great
I live in a wooded area in Central Louisiana, and had problems with spiders. Applied D-Fense SC, and got rid of my spider problem. Really works great!
Review by Patio King / (Posted on 6/17/2015)
Great Product
This was very effective to keep a variety of bugs out of the house. I sprayed the foundation around the house. Great residual, even with outdoor use. Also worked great in the basement sills and corners.
Review by Happy Customer / (Posted on 5/14/2015)
Love this product
I bought this product cause we don't know what we had but knew something was causing us to feel like something was crawling on us. Mixed product and used it once and we are free. We will keep using this product.
Review by Brownsugar / (Posted on 5/13/2015)
Will use in the fall
Have used a similar product before with great success. Cluster flies and landybugs invade our windows over the window when we don't treat ahead of time. In the past, I sprayed in the fall but skipped last fall. Mistake! This year I'm all ready. Fast service!
Review by Bill / (Posted on 4/28/2015)
Terrific product
I used this product in my battle against house centipedes, crickets and silverfish. It is odorless and leaves no visible residue. Most important, I am winning the battle.
Review by RonE / (Posted on 4/7/2015)
We have a Box Elder Bug problem. It is not an infestation as yet but getting to be a real problem. Since I sprayed with D-Fense SC I haven't seen many at all. Just a very few and I only used the small size (1 pint size). Still have a small amount left. I plan to reorder and spray again. I highly recommend this product. It worked for me and I have used a lot of different remedies.

Review by guadalisa / (Posted on 12/24/2014)
Amazing Product!
I've been waging a war with cockroaches in my garage for years. I thought I had some level of control with boric acid but after spraying with D-Fense, I needed a shovel to gather the dead roaches. It's been a week and I'm still finding more.

DIY RESPONSE: Glad to hear that D-Fense worked so well for you against roaches. One important note for other people reading this review, is that D-Fense works great against the large type roaches that breed outside the home, but we don't typically recommend it for the small German Roach.
Review by mooseherd / (Posted on 12/7/2014)
Great stuff!
This product worked great! I had a huge problem with crickets and minutes after spraying, they were coming out of cracks I didn't know I had! It made a huge difference and I haven't seen one since. I'm going to spray again, as recommended, and I'm sure that will be the end of them. I highly recommend this product.
Review by Rose / (Posted on 12/1/2014)
This product has worked great for me. Either I have an increase in cockroaches this year, which is certainly possible considering the conditions, or this product is better than what I was using. Either way I look at it is a win because the pests are always dead, everywhere I go.
Review by JP / (Posted on 11/5/2014)
the best product I ever used,definitely ordering more I highly recommended
Review by ash / (Posted on 11/3/2014)
Works great!
After just one spraying around the baseboards in my house, I have no live roaches. Lots dead ones. I would recommend this product!
Review by Jack / (Posted on 10/29/2014)
Worked well
I had to do a little math to get a gallon of mix at a time but I think I got it figured out. I was pleased there was no odor when using this product. It is very concentrated, probably bought too much but where we live spiders will always be a part of life so we will use it.
Review by Joe / (Posted on 9/24/2014)
Wow, works great
Great product. I couldn't reach my "bug guy" to spray for cluster flies, so through some internet searching I found www.doyourownpestcontrol.com, talked to the staff, the recommended a product, I sprayed the house and no flies. To think I spent $200 for the professional and here I get this for $35.50 and I used less than half the bottle ... saving big money and the product is working great
Review by J.Z. / (Posted on 9/20/2014)
Great stuff so far
I live in SC. We have what they call "Palmetto Bugs" which are nothing more that great big nasty roaches. My former bug guy had just sprayed and my back porch were cover up with these vermin. I sprayed about three weeks ago and have not seen one since. I also sprayed the corners under my front porch--no more spiders! Pretty amazing stuff.
Review by Wally / (Posted on 9/19/2014)
Great stuff!
I got immediate control with zero odor. This is the BEST online company to deal with, I've been ordering for years.

Sprayed one month ago for spiders and other bugs. I am still sweeping up bugs.
Review by JD / (Posted on 8/21/2014)
Great stuff, been using for years. Was paying a service for years. Spray the outside and inside once a month and you're done. Works great, just as good if not better than professional exterminators.

Graveyard at midnight
I had several swarms of cluster flies on bushes around the home and they were finding a way in. Tried this and 24 hours later there was silence. One treatment and they are all gone. Now two weeks later there is no trace of flies. Great Product, easy to use and dries invisible.
Review by Jed / (Posted on 7/25/2014)
Excellent product
This product controls all sorts of insects inside and outside of the house and garage... highly recommend ...

Squashes bugs dead
Excellent product, I've been using it for years. I used to get a lot of spiders and other insects. Now I see very few if any all summer long. No need to spend big $$ like I used to before I found this product from Do It Yourself. Great stuff
Review by Dan / (Posted on 7/16/2014)
On the spot job.
This product has done a great job around the perimeter of my home. A day after the first use, I noticed a decrease in flies, gnats, and spiders. I will continue to purchase and use this product for my home.

Used as a perimeter treatment. Kills roaches dead. Thanks...

D-Fense SC is your best Defense for bugs/insects
We had a professional pest control service for about 4 years. One day I asked the service tech, what was the name of the product he was using. He replied D-Fense SC. I looked on the internet and there it was sold by Do-it-yourself Pest control. Now I use the D-Fense SC monthly and have not seen any bugs/insects, nor do I need the professional pest control service. It works very well. Living in Southern New Mexico.
Review by Rich / (Posted on 6/30/2014)
Very Satisfied Customer
Tried the spray. No spiders, ants and so. Perfect for occasional pest control around the house. Recommended.
Review by Sebastian / (Posted on 6/26/2014)
Outstanding Product!
Used D-Fense SC Insecticide to get rid of cigarette beetles in our home. Followed the instructions and measurements that came with it, sprayed inside and outside our home, and it worked like a charm!! We also put up traps just in case, but every trap was empty. D-Fense SC got the job done! So happy with this product! Definitely recommend it!
Review by Winnie / (Posted on 6/18/2014)
FINALLY something that works!
Have had a MAJOR problem with hornets/wasps for over 7 years. They seem to like my Trex deck & rock wall. After spending $$ on landscaping, patio, retaining walls, etc, we NEVER got a chance to enjoy the area as we were always swarmed with wasps. I've tried natural/organic...stuff, "professional" stuff, etc...this TRULY is the ONLY thing that has worked! FINALLY, we can enjoy our patio & deck without fear of being stung. It's been over 2 weeks with fair weather & I still have not seen a wasp/hornet/fly, you name it! I just followed the exact directions on the package...works like a charm!

Spraying once took care of a most persistent Merchant Grain Beetles. Ken responded in no time, showing caring and knowledge. Both De-Fense SC Insecticide and DIY Pest Control company are tops.
Review by Ahuva / (Posted on 12/5/2013)
Cluster Flies no more
I bought this product to help control the cluster flies on the second level of my house in Michigan. I sprayed the inside and outside window frames. Before the spray I was having to kill about 10-15 flies per day in the fall in my son's 2nd floor bedroom at night. Within a few days of the spray the flies that did make it in the house all quickly died near the window. After a few days of vacuuming them up we haven't seen any more.

It's only been a few weeks but I'm very pleased.
Review by Big House / (Posted on 11/20/2013)
Great Product!
This is our third purchase of D-Fense SC Insecticide. We have found it works great on the Japanese ladybugs that swarm in early fall. Product works for months! We spray our exterior and that of our neighbor, and church.

D-Fense SC
We tried a lot of things for centipedes but the little crepies kept showing up. After reading several articles we tried the D-Fense SC and I'm glad to say to little buggers have not made an appearance since. Add to the fact we had no odor and no residue to contend with and we're pretty happy. I will by D-Fense SC again and I would recommend it to others
Review by shabsdaddy / (Posted on 10/26/2013)
Product worked with outstanding results. I sprayed around the house, in the house, and front and back yard. Haven't seen any bugs or spiders in over a month. Bought another gallon to get ready when spring hits. Bottom line I haven't found a product like this that works on any of the pest control markets.

This product really works. I recommend this product.

Pretty Good Stuff!
I had, what I call, an investation of Boxelder Bugs this Spring/Summer. I used several bug killers, but it appeared that the Boxelder Bugs viewed this is a treat and not a poison because they did not decrease in numbers. However, once I used D-Fense SC Insecticide - it reduced the population drastically within 24 hours. I believe that when Spring rolls around again and I do another treatment, I will have eliminated the evidence of Boxelder Bugs! I have saved this website and will purchase again! Thank you!!!

Earwig problem solves
I hate earwigs...they have been coming out every spring. I went to Home Depot a couple of times, trying to solve the problem....then found these folks at Do It Yourself. I sprayed this D-Fense spray around my house.....Finally, the problem got solved. It also got rid of the roaches that were around outside as well. I love this stuff!!

stink bugs
I bought D-Fense last year for those smelly stink bugs. I am buying
another to get ready for them in a couple of months. We did not
have these insects 3 years ago. Well any way I still got some in my
house but all and all I killed a bunch.

Spider problem
I have been having trouble with Black Widow and Brown Recluse spiders for a few years. I have been hiring very "high priced" professional pest control companies.
I decided to do my own research and obtain the same chemical they use.
I have used this product and have had good results. Am very satisfied with this product and this comany.
