Permethrin is a medication and an insecticide. [6] [7] As a medication, it is used to treat scabies and lice. [8]It is applied to the skin as a cream or lotion. [6] As an insecticide, it can be sprayed onto outer clothing or mosquito nets to kill the insects that touch them.
Cypermethrin is moderately toxic through skin contact or ingestion. It may cause irritation to the skin and eyes. Symptoms of dermal exposure include numbness, tingling, itching, burning sensation, loss of bladder control, incoordination, seizures and possible death.
Aquatic life is extremely susceptible to pyrethrin toxicity, and has been documented in species such as the lake trout. Although pyrethrins are quickly metabolized by birds and most mammals, fish and aquatic invertebrates lack the ability to metabolize these compounds, leading to a toxic accumulation of byproducts.

Chemical structure of permethrin, a common acaricide.. Acaricides are pesticides that kill members of the arachnid subclass Acari, which includes ticks and mites.Acaricides are used both in medicine and agriculture, although the desired selective toxicity differs between the two fields.
Raid is the brand name of a line of insecticide products produced by S. C. Johnson & Son, first launched in 1956.. The initial active ingredient was allethrin, the first synthetic pyrethroid. [1]
Pyrethroids are synthetic insecticides based on natural pyrethrum ; one common example is permethrin. Pyrethrins are often sold in preparations that also contain the synthetic chemical piperonyl butoxide , which enhances the toxicity to insects and is faster acting compared with pyrethrins used alone.
Allethrin I (R = −CH 3) Allethrin II (R = −COOCH 3). The allethrins are a group of related synthetic compounds used in insecticides.They are classified as pyrethroids, i.e. synthetic versions of pyrethrin, a chemical with insecticidal properties found naturally in Chrysanthemum flowers.
Poisoning in cats can result in seizures, fever, ataxia and even death. Poisoning can occur if pyrethroid containing flea treatment products, which are intended for dogs, are used on cats. The livers of cats detoxify pyrethroids via glucuronidation more poorly than dogs, which is the cause of this difference. [ 15 ]
