Bifenthrin is a pyrethroid insecticide used primarily against the red imported fire ant by influencing its nerve system. It has a high toxicity to aquatic organisms. Although it is listed as a restricted use chemical in the United States, it is allowed to be sold for daily use, provided that the product sold has a low concentration of bifenthrin. The chemical has been discovered and developed by FMC Corporation. Products containg Bifenthrin include Talstar, Maxxthor, Capture, Brigade, Bifenthrine, Ortho Home Defense Max, Bifen IT, Bifen L/P, Torant, Zipak, Scotts LawnPro Step 3, Wisdom TC Flowable, FMC 54800 and OMS3024.[1]
