Permethrin is an insecticide in the pyrethroid family. Pyrethroids are synthetic chemicals that act like natural extracts from the chrysanthemum flower. Permethrin is used in a number of ways to control insects. Products containing permethrin may be used in public health mosquito control programs. They may be used on food and feed crops, on ornamental lawns, on livestock and pets, in structures and buildings, and on clothing. Permethrin may also be used in places where food is handled, such as restaurants. Permethrin was was re-registered in 2006 in USA since permethrin is virtually non-toxic to humans and no systemic effects have been reported in either EPA or FDA tests.
Permethrin can affect insects if they eat it or touch it. Permethrin affects the nervous system in insects, causing muscle spasms, paralysis and death. Permethrin is more toxic to insects than it is to people and dogs. This is because insects can't break it down as quickly as people and dogs.
Acts on the nervous system of insects, disturbs the function of neurons by interaction with the sodium channel.

Non-systemic insecticide with contact and stomach action, having a slight repellent effect.
A contact insecticide effective against a broad range of pests. It controls leaf- and fruit-eating Lepidoptera and Coleoptera in cotton, at 100-150 g/ha, in fruit, at 25-50 g/ha, in tobacco, vines and other crops, at 50-200 g/ha, and in vegetables, at 40-70 g/ha. It has good residual activity on treated plants. It is effective against a wide range of animal ectoparasites, provides >60 d residual control of biting flies in animal housing, at 200 mg a.i. (as EC)/m2 wall or 30 mg a.i. (as WP)/m2 wall, and is effective as a wool preservative, at 200 mg/kg wool.
