Metofluthrin is a pyrethroid used as an insect repellent.[1] The vapors of metofluthrin are highly effective and capable of repelling up to 97% of mosquitoes in field tests.[2] Metofluthrin is used in a variety of consumer products, called emanators, for indoor and outdoor use.[3][4] These products produce a vapor that protects an individual or area. Effectiveness is reduced by air movement. Metofluthrin is neurotoxic, and is not meant to be applied directly to human skin.[5]

Although metofluthrin has insectidal properties against other insects, it may not be an effective repellent for insects other than mosquitoes.[6]
