Permethrin is a medication and an insecticide. [4] [5] As a medication, it is used to treat scabies and lice. [6]It is applied to the skin as a cream or lotion. [4] As an insecticide, it can be sprayed onto outer clothing or mosquito nets to kill the insects that touch them.
Contact with a sprayed plant or "weed" can have an effect upon local wildlife, most notably insects. A cause for concern is how pests, the reason for pesticide use, are building up a resistance. Phytophagous insects are able to build up this resistance because they are easily capable of evolutionary diversification and adaptation. [49]
Chemical structure of Allethrin isomers Chemical structure of Permethrin isomers. A pyrethroid is an organic compound similar to the natural pyrethrins, which are produced by the flowers of pyrethrums (Chrysanthemum cinerariaefolium and C. coccineum).
Permethrin can be applied as a spray. The effects are not limited to mites: lice, cockroaches, fleas, mosquitos, and other insects will be affected. Ivermectin can be prescribed by a medical doctor to rid humans of mite and lice infestations, and agricultural formulations are available for infested birds and rodents.
The metabolism of bees and humans is sufficiently different that bees can safely collect nectars from plants that contain compounds toxic to humans. The honey produced by bees from these toxic nectars can be poisonous if consumed by humans. In addition, natural processes can introduce toxic substances into honey produced from nontoxic nectar.
