Deltamethrin is a pyrethroid insecticide. Pyrethroids are synthetic compounds made to mimic the pyrethrins that are isolated from chrysanthemum flowers. Deltamethrin 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. Deltamethrin can be found in a wide variety of products used in agriculture, on golf courses, gardens, and lawns, indoors, and even on pets.
