Temprid FX is over 4 times more expensive per fl oz than Bifen IT. I get that the residual effects of Bifen IT last about half that of Temprid FX. If they work about the same overall, wouldn't it make sense to just use Bifen IT? What are your thoughts on this?
Temprid FX would be the best insecticide to use for active roach infestations due to the 2 active ingredients and dual modes of action it uses. Bifen IT would be suggested for general maintenance or preventative applications but not the recommended product if you have active roaches.
Active roach infestations require a combination of products and repeat treatments every 7-14 days to eradicate. Using a residual spray alone will not fully eradicate a roach colony. We recommend one of our Roach Control Kits to provide you with a residual insecticide, roach bait and insect growth regulator to help stop the reproduction. These kits provide enough products for the initial treatment as well as 2-3 follow up treatments.
