On some airlines measures are taken to protect passengers - for example by spraying cabins - on others they are not.

Also, the Department of Transportation must post online a list of countries that force airlines to spray cabins with insecticide.

Liquid wood finishes are applied via automated spray guns in an enclosed environment or spray cabin.

Australia (like some other countries: New Zealand, Jamaica, Panama, Fiji, India, Uruguay, etc) used to spray cabins prior to disembarkation on arrival in Australia.
