On-Board Airline Pesticide Spraying Propels Controversy

By following the dictates of various foreign governments, major U.S. airlines may well be running afoul of their own. What’s at issue is the spraying of occupied passenger planes with pesticides. This practice, called “disinsection,” is required by a number of tropical and Pacific Rim nations before flights are permitted to land there. These countries, with the support of the World Health Organization (WHO), say such disinsection is necessary to prevent non-native disease carrying insects from being unintentionally imported as aircraft stowaways.
