Why is permethrin effective for outdoor tick prevention?

Answer

It kills ticks on contact

Permethrin is a highly effective chemical treatment for clothing and outdoor gear. Unlike standard repellents that merely deter insects from approaching, permethrin is a contact insecticide. When a tick comes into contact with fabric treated with permethrin, the chemical works to kill the tick, providing a strong barrier against infestation.
