Welcome to Do-It-Yourself Pest Control

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.

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.

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!

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

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!!

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.

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!
