Mode of Action:

Malathion has been registered for use in the US since 1956. Is it used in agriculture to control many types of insects, home use, and public health pest control programs for controlling mosquito-borne illnesses. The EPA lists Malathion as part of an integrated overall strategy to control mosquitoes.  Fyfanon EW is an adulticide, used to kill adult mosquitoes.

90% of  overall malathion used in mosquito adulticide applications are made by ground application. However, in situations of heavy mosquito presence across large geographic areas, aerial application is an important method of application. Less than 1% of spraying for mosquitoes is malathion aerial spray.
