Customer Reviews for Bifen IT

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.

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

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.
