Customer Reviews for Bifen IT

Sprayed all over the house, basement kitchen rooms. Fleas have went away, but now need to buy another product to make sure they won't come back. Great product?

Bought Bifen to get rid of 2 wasp nests. Followed all directions. Saturated both nests twice. Next day I attempted to remove the nests. All wasps were still alive and got stung multiple times. Called your company and was told this product takes 2 weeks to work. Nothing about 2 c weeks in product read out nor from your customer support about c 2 weeks. Tried to get a refund, told not possible. Your company is the worst.

An arborist recommended Bifen IT as a do it yourself approach to address an infestation of carpenter ants in 3 walnut trees on my property. I applied the product as recommended using a pump up sprayer and reaching up the tree to the extent of my height and reach (I'm 6' tall) and then a 2-3 foot radius around the base. I applied it two weeks ago and have not seen any ants on the tree or at the base since. I had a pretty significant problem. I'm about to put a second application on but not sure it's necessary? Needless to say, I'm very pleased with the results. The online ordering process worked easily and delivery was quick and as projected. I recommend this if you have a similar situation. Thank you.

Took care of my ant problem that I had been dealing with for years. After reading reviews I decided to order Biden IT. I sprayed it outside the house three feet up and out then sprayed around the baseboard in the house. No more ants!!!

I used 1oz to one gallon of water in a pump sprayer and sprayed on two of my Maple trees. I also sprayed around the base of the trees and on some of the lawn. A couple hours later I went out and there were dead SLFs. The next day it rained, I did not check. The following day, I went out (two days after application) and there were quadruple amount dead. This stuff works. I will do an application all over my lawn and on the sides of my house as I have seen SLFs climb. What I've noticed is that SLF's don't fly up, they walk up and they fly down. They jump to get to different heights as well, I actually saw this. This is my theory as why the Sticky stuff people use goes about breast height. I saw SLFs walking up my siding and up trees. I have yet to see any actually fly upwards. Spray this ingredient and get results.

Biden I/T was initially recommended to me by our Expert Beaver trapper. I'm a Senior who prefers easy directions and effective, lasting results to especially eradicate mosquitoes. This product has worked very well for the last five No.Georgia Spring through Fall months with 1-3 applications over a wide area! PLEASE PROTECT MY PERSONAL INFORMATION!

I have used Bifen IT for several years with very good results. Purchasing by the gal. makes it very economical to use. With 1 oz. per gal. of water it will make 128 gal.

Nuclear war in a pump sprayer on ants. Sprayed the outer perimeter of my house and that ended that problem. Hooked for life

Had a carpenter ant problem. One application of Bifen IT and I didn't have a problem anymore. Enough said. One of the few products I've bought in my life that I have been 100% satisfied with.

This product was absolutely amazing! It killed all the spiders outside the house! There was an infestation of spiders that had been living rent free for too long. Follow the instructions and you will be happy to get rid of your moochers too!

I'm fairly obsessive-compulsive when it comes to my lawn and yard. Bifen IT has knocked out anthills, on the DoMyOwn website. IT worked wonderfully. It didn't kill grass yet it took care of the any colony within days of the application. Since then I've sprayed my neighbors enclosed sunroom and foundation which were infested with ants. Most recently, I found it eliminates cicada killers (large wasps). Finally, as a preventative measure I sprayed Bifen IT on the trunks of the trees in my yard, including a rare Kentucky Coffeetree and to my surprise I found piles of dead Spotted Lanternflys a few days later. I never knew that this invasive species was present. I can't say enough good things about this product.

Two applications from swarms to none 0 spotted lantern flies. Seems to be holding visitors at bay.

Used it for the last two summers in the south and it has worked wonders. We were using another type of spray and kept seeing roaches. Now, after switching to Bifen, we haven't seen any. Definitely recommend.

Very happy to have received product much earlier than expected. We had a big problem with mosquitos in south Texas after 2 heavy rainstorms. There were clouds of mosquitos. Sprayed our two acres with this product and mosquitos have dwindled down to just a few. Only applied once. We didn't want to diminish the bees and butterflies.

I got this because I have an elm tree that has elm beetles. It works very well killing the beetles. I also spray my yard for ticks and it works well there also.

I sprayed a mixture of the Bifen (little goes a LONG way) all around the exterior of my house and on trunks of my trees. The next DAY, I noticed a significant drop in mosquitos. Previously I would have immediately been swarmed upon stepping outside, but now I haven't noticed a mosquito in a couple days.

Spider and pesky bugs finding ways into my house. Remedy was to spray around perimeter of home. Each time I applied I could see dead spiders and other insects. It's nice to know when you can see results!! HAPPY HAPPY!!
