Not as good as Cyper WP or Bifen I/T
By Joe on 05/17/2010
The residual action on this product is almost none existent. You almost have to spray the bugs directly in order to notice a significant effect. Even if you mix a lot more, you will end up using a 1 pound bag very fast. When I used Cyper WP or Bifen IT the residual action keeps on killing roaches, spiders, crickets, etc... weeks after I sprayed. Cyper and Bifen also lasted longer because you did not need to use a lot for them to be effective.
