How Does Insect Repellent Clothing Work?

Are insect repellent clothes effective? Insect repellent clothing is treated with a chemical called permethrin, which is a synthetic version of a natural insect repellent called pyrethrum that's derived from chrysanthemums. Permethrin acts as a neurotoxin to insects and causes paralysis and death. When applied to clothing, permethrin forms a lasting barrier on own clothing that repels insects.

Permethrin has been used for over 30 years as an insecticide and has been evaluated by numerous regulatory agencies worldwide, including the Environmental Protection Agency (EPA) and the World Health Organization (WHO), who deemed it safe for human use with proper application.

According to the Centers for Disease Control and Prevention (CDC), permethrin-treated bug repellent clothing provides long-lasting protection against mosquitoes, ticks, and other insects that can transmit diseases such as Lyme disease and West Nile virus.
