Some countries require inbound flights (and select outbound flights) to undertake “disinsection,” meaning the removal of insects, in cabins and hold areas, prior to arrival in the country. These regulations vary by country, with some requiring the spraying of aerosolized insecticide while passengers are on board, while others allow treating with residual insecticide or spraying aerosolized insecticide while passengers are not on board. Additionally, some countries have disinsection regulations for specific regions (within or outside of the country) or public health scenarios such as areas with known outbreaks of the Zika virus.

Before any trip, operators should confirm any specific disinsection regulations that apply to their destination and ensure they are prepared with necessary materials. The map below provides an overview of major countries with current disinsection requirements. A full list can be found at the U.S. Department of Transportation’s aircraft disinsection homepage.
