Description
A synthetic pyrethroid Insecticide. Permethrin is stable to light. Compared to other insecticides, pyrethrins have low toxicity to mammals (except for cats). They break down fairly rapidly at leave no harmful residues. Permethrin is used for ticks, flies, bees, lice, and spiders. Some insect repellents also contain permethrin.
Permethrin was discovered in 1973. It is widely used in cremes and lotions for the treatment of lice and scabies. Permethrin is also contained in some tick collars and medication for dogs. It, however, is highly toxic to cats and some aquatic organisms.
