Question: Which pesticides are currently recommended by the World Health Organization for aircraft cabin disinsection?
Answer: The cited reference notes: “Aircraft disinsection is allowed under international law, but not all countries require it. The U.S. Environmental Protection Agency (EPA) has not currently approved any pesticides for use in passenger cabins on commercial aircraft. The U.S. Department of Transportation provides information on which countries require disinsection on inbound flights. The only pesticides recommended by the World Health Organization (WHO) for aircraft disinsection are synthetic pyrethroids (permethrin, d-phenothrin, and 1R-trans-phenothrin). Other pesticides, including DDT (dichlorodiphyltrichloroethane), were used to disinsect aircraft several years ago but are no longer used.” (https://www.cdc.gov/niosh/topics/aircrew/pesticides.html; accessed December 2017)
