Bifenthrin is a pyrethroid insecticide. Pyrethroids are synthetic compounds made to mimic the pyrethrins that are refined from chemicals found in chrysanthemum flowers. Bifenthrin is a broad-spectrum insecticide that works by interfering with a nerve cell's ability to send a normal signal by jamming open tiny gates on the cell that need to open and close rapidly to carry the message. Bifenthrin is used in agriculture and residential settings, both indoors and outdoors.
