The use of pesticides on flights is a common practice to prevent the spread of insect-borne diseases. This process, known as disinsection, involves spraying pesticides or wiping down the cabin before or during the flight. While this is allowed under international law, it has raised concerns among passengers about potential health risks. The type of pesticide used, such as permethrin, is generally considered safe for humans but can cause irritation in some individuals. As a result, regulations vary across countries, with some allowing pesticide use only when the aircraft is empty and others requiring disinfection of all inbound flights. These regulations aim to balance the prevention of insect-borne diseases and addressing passenger concerns. So, while pesticides themselves may not set off airport security, the regulations around them are crucial in ensuring safe travel.
| Characteristics | Values |
|---|---|
| Pesticides allowed on planes | Yes, but only when the aircraft is completely empty, with at least one hour before anyone boards. The plane must also be ventilated for 30 minutes before anyone gets on. |
| Pesticides allowed in carry-on luggage | No, aerosol insecticides are not allowed in carry-on luggage. |
| Pesticides allowed in checked luggage | Yes, as long as they are not labelled as hazardous material (HAZMAT). |

Aerosol insecticides are allowed in checked bags, but not carry-ons
When travelling, it's important to be aware of the restrictions on what you can and cannot bring with you, especially when it comes to aerosol insecticides. These products are typically allowed in checked bags but are prohibited in carry-on luggage.
Aerosol insecticides, while useful for personal protection against insects, must be carefully packed when travelling. The Transportation Security Administration (TSA) guidelines state that aerosol insecticides are permitted in checked bags as long as they are not labelled as hazardous material (HAZMAT). This means that you can include them in your checked luggage, which is the baggage that gets checked in and stored separately from passengers during the flight.
However, it's important to note that aerosol insecticides are not allowed in carry-on bags. Carry-on luggage, also known as hand luggage or cabin baggage, must not contain these items. This restriction is in place for all passengers, regardless of their destination or airline.
It is worth noting that only bug repellents meant to be applied to the skin are accepted. Insect repellents or insecticides designed to be sprayed directly at insects are prohibited in both carry-on and checked baggage. This restriction is in place to maintain safety and comply with regulations. Additionally, permitted aerosol release devices, such as buttons or nozzles, must be protected with a cap or similar protection to prevent accidental release.
When packing aerosol insecticides in checked bags, it's important to follow any size and quantity restrictions outlined by the TSA. These restrictions are in place to ensure the safety and comfort of all passengers and crew members. By adhering to these guidelines, travellers can ensure they are prepared for their journey while also complying with airport security measures.

Permethrin is the most commonly used pesticide
While it is not clear whether pesticides can set off airport security, permethrin is the most commonly used pesticide worldwide. It is a synthetic chemical that kills and repels mosquitos, ticks, and mites. Permethrin is used in tropical areas to prevent mosquito-borne diseases such as dengue fever and malaria. It is also used to treat scabies and head lice in humans and is found in flea treatments for dogs.
Permethrin is a pyrethroid, which works by disrupting the function of the neurons of lice, mites, and insects. It is highly toxic to cats and fish. It is available in various forms, including liquids, powders, dusts, aerosol solutions, sprays, and treated clothing. Treating clothing with permethrin is a common protective measure, especially for those travelling to tropical areas. It is also used in mosquito nets, which increases their effectiveness by killing parasitic insects before they can find gaps or holes in the net.
The British and US armies treat all new uniforms with permethrin to protect soldiers from biting insects. It is also used in cattle ear tags and flea collars, and in spot-on treatments for dogs. There are currently more than 1400 registered products containing permethrin.
While permethrin is generally considered safe for humans, it can cause irritation in some individuals. It is approved for use on and around people over the age of two months in the United States. However, it is important to follow label instructions and take steps to minimize exposure. If exposure occurs, it is important to follow the First Aid instructions on the product label carefully.

Disinsection is the term for spraying pesticides to prevent insect-borne diseases
The pesticide typically used for disinsection is permethrin, a synthetic chemical that kills and repels mosquitos, ticks, and mites. While permethrin is generally considered safe for humans, it can cause irritation in some individuals. In the United States, the CDC has concluded that there is no evidence that spraying pesticides inside aircraft cabins is effective in preventing the spread of mosquito-borne diseases, and therefore does not recommend this practice.
The decision to conduct disinsection and the methods employed vary by country. Some countries, such as the United States, do not allow aerosol insecticides in carry-on baggage but permit them in checked bags as long as they are not labelled as hazardous materials. Passengers concerned about disinsection should contact their airline for the latest information.
To ensure the safety of passengers and crew, employers should review their protocols and adhere to relevant safety guidelines, such as WHO guidelines on disinsection and manufacturer guidance for specific pesticide products. Additionally, staff who apply insecticides should be trained on their proper application, and alternative methods to prevent insects from travelling on aircraft should be considered.

Countries have different rules for disinsection, depending on inbound flight risk
While insecticides and pesticides are not permitted in carry-on luggage, they are allowed in checked bags as long as they are not labelled as hazardous materials.
The spraying of pesticides on planes is a practice called disinsection, which prevents the spread of insect-borne diseases like Zika, dengue fever, and malaria. Countries have different rules for disinsection, depending on the risk posed by inbound flights.
Some countries require disinsection on all inbound flights, while others only accept wiping down or spraying without passengers on board. For example, Australia, Fiji, New Zealand, Jamaica, and Chile allow spraying without passengers on board. On the other hand, countries like Indonesia, France, Thailand, the United Kingdom, Korea, and Italy only disinsect flights arriving from regions where insect-borne diseases are widespread within a specific timeframe.
Italy, in particular, has specific disinsection requirements. It mandates disinsection for aircraft arriving from countries where Aedes aegypti mosquitoes are present, which includes the United States and France, even if there is no current disease transmission. Italy also recognizes the self-spray method as an alternative to residual treatment. However, due to inconsistent enforcement across airports and local authorities, it is not recommended as a primary disinsection method.

Insect repellent is allowed in carry-on luggage but is subject to size restrictions
Aerosol insecticides are not allowed in carry-on luggage but are permitted in checked bags, provided they are not labelled as hazardous material (HAZMAT). These insecticides must be non-flammable and meet the parameters set by the International Air Transport Association (IATA). Solstice® Propellant is often used to meet these requirements.
It is important to note that some countries may have specific requirements for insect repellent or insecticide use on inbound flights. For example, Italy requires disinsection for all flights arriving from areas with Zika virus transmission or the presence of the Aedes aegypti carrier. Mauritius, Macau, Peru, South Africa, and Switzerland also have specific requirements for inbound flights from regions with mosquito-borne diseases or high risks of infectious diseases.
Additionally, some airlines may choose to spray pesticides inside the cabin before landing, such as British Airways. The pesticide used, permethrin, is generally considered safe for humans by the World Health Organization (WHO) and is effective in preventing the spread of mosquito-borne diseases. However, individuals with conditions like Multiple Chemical Sensitivity (MCS) may experience adverse reactions, and the U.S. Centers for Disease Control and Prevention (CDC) does not recommend this practice due to a lack of evidence of its effectiveness.
