AEROSOL INSECTICIDES

Can you bring aerosol insecticide on a plane?

TSA does not allow aerosol insecticide in carry-on on US flights. It may travel in checked baggage only if it is not labeled as hazardous material; FAA excludes sprays aimed at air or insects from the skin-repellent toiletry exception.

Carry-on baggage

Prohibited

Do not bring aerosol insecticide through a TSA checkpoint. A small can does not convert room insecticide into skin repellent.

Checked baggage

Allowed with conditions

TSA conditionally permits aerosol insecticide in checked baggage when it is not labeled HAZMAT. A flammable or otherwise regulated can has no ordinary passenger exception; protect an accepted nozzle against release.

TSA’s checked condition does not extend to HAZMAT insecticides.

Room spray versus skin repellent
