By Brian in Norman, Ok on 06/28/2010

Not for fleas!
1 of 5 stars
By Kimber in Marietta, GA on 09/24/2014

I bought this to correct the flea problem in my basement but it hasn't touched them. After multiple applications, i still have the same problem. I went back to Ultracide and it's fine now.

Expert Response  Expert response:

For fleas, you should use both an adulticide and an Insect Growth Regulator, or IGR. Ultracide contains both of these, so it is a great choice for treating fleas indoors. Bifen IT is only labeled as a crack and crevice spray for indoor treatments, so it would not be an appropriate adulticide for indoor flea treatments.
