Permethrin Class II to Class III, US- EPA has classified it as RUP (Restricted Use Pesticide). Permethrin, like all synthetic pyrethroids, is a neurotoxin. Symptoms include tremors, incoordination, elevated body temperature, increased aggressive behavior, and disruption of learning. Laboratory tests suggest that permethrin is more acutely toxic to children than to adults. Boils at 200 °C.  Thus, most of insecticide evaporates during processing itself, moreover giving toxic fumes.
