Cypermethrin
Cypermethrin is a synthetic pyrethroid used as an
Insecticide in large-scale commercial agricultural applications as well as in consumer products for domestic purposes. It behaves as a fast-acting neurotoxin in insects.
Cypermethrin is easily degraded on soil and plants but can be effective for weeks when applied to indoor inert surfaces. Exposure to sunlight, water and oxygen will accelerate its decomposition.
Cypermethrin is highly toxic to fish, bees and aquatic insects, according to the National Pesticides Telecommunications Network (NPTN).
Cypermethrin is found in many household ant and cockroach killers, including Raid and ant chalk.
Uses:
Cypermethrin is used to control to a wide range of insects.
Cypermethrin is also used to control flies and other insects in animal houses; and mosquitoes, cockroaches, houseflies and other insect pests in public health. Also used as an animal ectoparasiticide.
Biochemistry:
Cypermethrin acts on the nervous system of the insect, disturbs the function of neurons by interaction with the sodium channel.
Mode of action:
Cypermethrin is a non-systemic
Insecticide with contact and stomach action. Also exhibits anti-feeding action. Good residual activity on treated plants.
