Phenothrin is an insecticide that is used to kill a variety of insects, including mosquitoes, flies, fleas, and ticks. It is a synthetic pyrethroid, which is a type of synthetic chemical compound that is similar in structure to a natural pyrethrin. Phenothrin works by disrupting the nervous system of the insect, causing paralysis and death. It is often used in combination with other insecticides to increase its effectiveness. It can be applied as a liquid spray, dust, fog, or aerosol.
