Chlorempenthrin is primarily used as a synthetic pyrethroid insecticide, especially in household and public health applications. It is commonly found in mosquito coils, electric vaporizers, and other indoor pest control products designed to repel and kill flying insects like mosquitoes and flies. Due to its fast-acting knockdown effect and low mammalian toxicity when used as directed, it is well-suited for use in residential environments. It works by disrupting the nervous system of insects upon exposure, leading to paralysis and death. Its volatility allows it to disperse effectively in the air when heated, making it ideal for space treatments in homes, hotels, and camping areas.
