The process of disinsection is required by WHO (World Health Organisation) and local health authorities to prevent the spread of infectious diseases, e.g. Malaria.
On some of our routes, we spray the inside of the aircraft with insecticides, which is recommended under the WHO based on their safety and effectiveness.
The spray we use onboard is Phenothrin (1R-trans phenothrin), which dissipates within a few minutes after being sprayed in the cabin.
Our cabin crew will make an onboard announcement when the spraying of insecticides is about to take place. We encourage customers to use this opportunity to cover their nose, eyes and mouth if they wish to do so.
