Metofluthrin is a pyrethroid used as an insect repellent. The vapors of metofluthrin are highly effective and capable of repelling up 97% of mosquitoes in field tests. Metofluthrin is used in a variety of consumer products, called emanators, for indoor and outdoor use. These products produce a vapor that protects an individual or area; however, metofluthrin is not meant to be applied directly to human skin. Although metofluthrin has insectidal properties against other insects, it may not be an effective repellent for insects other than mosquitoes.
