Permethrin is a synthetic pyrethroid, a type of insecticide. It works by attacking the nervous systems of insects.
- Permethrin disrupts the sodium channels in insect nerve cells, preventing proper nerve signal transmission. This disruption causes paralysis and, ultimately, death in insects. It’s highly effective against a broad spectrum of insects, including lice, ticks, fleas, and mosquitoes.
Different formulations exist, impacting application methods and duration of effectiveness. Always follow product instructions carefully.
Creams and lotions are applied directly to the skin. Sprays can treat clothing, bedding, or other surfaces. Treatment frequency depends on the specific product and infestation severity.
While generally safe for humans when used as directed, permethrin can cause skin irritation in some individuals. Always test a small area first. If irritation occurs, discontinue use and consult a doctor.
