Permethrin
Permethrin
Permethrin (pronounced: pər-ˈme-thrən) is a synthetic chemical, widely used as an insecticide, acaricide, and insect repellent. It belongs to the family of synthetic chemicals called pyrethroids and functions by disrupting the nervous system of insects.
Etymology
The term 'Permethrin' is derived from its chemical name: 3-phenoxybenzyl (1RS)-cis, trans-3-(2,2-dichlorovinyl)-2,2-dimethylcyclopropanecarboxylate. It was first synthesized in 1973, and its name is a blend of the words 'permethric acid' (from which it is derived) and 'nitrogen' (a key element in its composition).
Usage
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.
