Customer Reviews for Bifen IT

This use to be best in the market chemical make up has been diminished and now it is worthless.

  Expert response:
Bifen has not changed in formulation but insects can develop resistance if they are exposed to it continuously over several years. It is recommended to rotate to a different insecticide every few years to prevent this, products such as Temprid FX or Demand CS are great to use.

Safe for mammals but highly toxic to bees. I saw the reviews and was relieved to find it was mostly safe for humans and dogs, but it's highly toxic for bees.

Oder this stuff and went by directions three time and still getting bitten by mosquitoes! Lesson learned wished I could get my money back but I'm sure that they'll come up with an excuse not to refund…..

  Expert response:
We are sorry your experience with Bifen was not as expected. Bifen is considered a repellent because insects can detect it. This does not mean they are truly repelled from the area they can just choose to avoid it as they know something is there. They must contact the treated area to be effected by the product though and you will still see some in the area. You can apply Bifen every 7 days if using the lower dose during heavy pest pressure if needed. For mosquitoes key is to apply to the underside of leaves on trees/bushes which is where the adults lay during the day, as well as shady areas. You would not treat entire areas of the lawn that are in full sun as it is not habitable for them there.

I am infested from fleas and biting gnats-midges. This did nothing. I have been using permethrin-sfr and nyguard IGR for 3 weeks- 7 days apart and WOW, knock down 85%. Just awaiting for my next shipment :)

I sprayed this AND spread 40 lbs of DeltaGard G granules over my 6,000 SQ ft lot and it did NOT kill the millions of springtails plaguing my family. This has been a huge disappointment and an even larger financial loss.

After extensive research on this site, I chose to combat my clover mite dilemma indoors and outside with this Bifen IT concentrate. I also used it along with PT Tri-Die Pressurized Dust Insecticide for inside. I'm almost 2 months into trying to kill these mites and neither one has worked. The Bifen IT is concentrated and will last a long time, but it hasn't touched any mites, inside or outside. The pressurized dust insecticide is listed as having an accompanying straw for crevasses and under baseboard/trim. Mine did not have it. Had to duct tape a straw from a WD-40 can onto nozzle hole to even be able to use mine. I would think at least one of these professional products would be effective....but I still have a problem.

I have used it for months now for roaches thinking eventually it will help and it has not helped at all. Very disappointed!

  Expert response:
We are sorry to hear results were not as expected with the Bifen IT. This product is not recommended if you have an active infestation of roaches. If you see an occasional roach, this can be used indoors and outdoors for control. Please check out our Roach Guide for tips on how to treat and prevent roaches. https://www.domyown.com/how-to-get-rid-of-roaches-a-458.html

This product did not dilute well and kept clumping while I used my sprayer. It kept clogging my sprayer. I lost patience and threw away the last quarter gallon. I will stick to Talstar P, which dilutes nicely and doesn't clog the sprayer. It was an effective product where sprayed.

White flies seem to be immune to this product. Works great on ants though.

Did not mix well with water. Continually clogged my sprayer nozzle tip. I had to throw this product away. I could not even spray one tank.

Expensive and does nothing for springtails. Bought the bifen granules as well and they were also ineffective. Can buy similar products at Walmart for a quarter of the price.

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.

I was hoping the would kill ants and spiders instantly. The ants move right through the solution. I added more IT Solvent and less water, still no great result with the ants and spiders. I've sprayed even my vehicle and they are still in there. I'm in a woody area and I don't think it's a fix for this. I'm sad.

Mixed and sprayed spiders per directions Several times in the same area with Biden IT and didn't kill spiders . Spiders are not dangerous just a nuance

Was this review helpful to you?  YesNo

Biden IT does not kill spiders as advertised. I mixed Biden IT per directions , sprayed directly on spiders and problem area. The next day spiders were still alive. The spiders are not dangerous just more of nuance. I sprayed several times, no success

Have used double strength and the roaches here swim in it then walk away. They then bring their friends back in the morning and walk through the areas like an insecticide never existed! These are California Central Valley Roaches of several species, large to small. They react to professionally placed insecticides the same way. I think they are from the Bikini Atoll.

We have a millipede problem at our home in Florida. This product was recommended for millipede control. Applied two thorough applications a week apart around the perimeter of our home (4 gallons of mixture) and it had no effect at all. What a waste of money. And I bought a gallon of this useless product.

This is the 2nd thing I bought for no see ums. The 1st one I as told..oh yes it works for them. Well I did exactly as directions said, oh no it doesnt. So I was told well try this because this really does. Well if this really does why wasnt I told that the 1st time. So I tried this one. Used exactly like it says to......well it really doesnt. So I'm done wasting my money on what "really works" that doesnt really work. It's a 1 star because leave it blank for a 0 star.

We recently turned our entire backyard into a rock garden. We love the low maintenance, however our dog would sometimes poop or pea & we started getting flies ... I tried solutions with vinegar and ammonia but nothing was helping... Finally came across this solution & it works great. We can enjoy our beautiful back patio

I read all the wonderful reviews about how quick and effective this product was, but honestly that's not been my experience. I've sprayed twice two weeks ago and have seen only three dead roaches over the whole two weeks. However, I've seen a dozen big and tiny ones running around still in all rooms. It seems the only way this product kills the insect is if I spray it directly. Not a happy camper.

  Expert response:
Thank you for your review. We apologize you have not received the expected results. We would like to take some time out to help troubleshoot with you but will need a little more information. Could you please tell us the rate at which you are using the Bifen and how often? Also, I see that your target pest is roaches, are you using any Growth Regulator (IGR)? The Bifen will work on the adults and the IGR will help stop the reproduction process. A good IGR for roaches would be Gentrol found here https://www.domyownpestcontrol.com/gentrol-igr-concentrate-p-211.html. If you have any further questions please give us a call at 866-581-7378.

Bought this and followed all instructions, even used it along with solvent to help adhere better. It deterred midges for like a day and they all came back. Some died but most of them just danced on where the Bifren IT was sprayed on. It didn't kill anything but like 10 percent. I wish I didn't spend the money for it. I also reapplied in the same areas and invested in a hand pump spray... Sooo sad
