In today’s global aviation environment, ensuring the health and safety of passengers, crew, and ecosystems goes beyond cabin service and flight operations—it includes strict adherence to aircraft disinsection protocols. With growing concerns over the international spread of vector-borne diseases and invasive pests, many countries now require inbound flights to perform disinsection using approved insecticide methods. For airline operators, procurement teams, and aviation safety officers, understanding these requirements—and sourcing EPA-registered, WHO-compliant solutions—is essential to maintaining compliance, avoiding penalties, and safeguarding public health.

Global aviation doesn’t just move people and cargo—it can also inadvertently transport pests and disease vectors across borders. That’s why aircraft disinsection is a critical part of international aviation protocols.
Disinsection is the process of eliminating insects on board an aircraft using approved insecticides. It’s often mandated by countries to protect their ecosystems and public health from pests that may carry diseases such as:
Malaria
Zika virus
Yellow fever
Dengue
Agricultural pests
Aircraft disinsection is regulated by global health bodies, such as the World Health Organization (WHO), and aviation authorities, such as the International Civil Aviation Organization (ICAO). Additionally, individual countries enforce their own entry requirements, making compliance a complex yet essential task for airlines and operators.

✈️ What Is Aircraft Disinsection?
According to the WHO, aircraft disinsection refers to treating an aircraft’s interior, cargo hold, and/or passengers’ cabin with insecticides to eliminate or prevent the entry of insects. There are several approved methods:
Common Aircraft Disinsection Methods
Pre-embarkation spraying (Pre-Spray)
Applied before passengers board.
Used inside the cabin for residual effect.
Top of descent spraying
Performed in the last 30 minutes before landing.
Applied while passengers are on board.
Not currently approved by the EPA for use in the U.S.
Blocks-away spraying
Sprayed after doors are closed but before taxiing.
Used primarily in flights to Australia and New Zealand.
Residual treatment
Conducted on aircraft interiors at set intervals.
Effective for multiple flights over a fixed period.

5. Cargo hold aircraft disinsection (1-Shot)
Applied in the cargo area before loading.
EPA-approved for use in U.S.-originating flights.
Bold compliance isn’t optional—countries like Australia, New Zealand, and South Africa can fine or even refuse entry to aircraft that haven’t followed their aircraft disinsection protocols.
EPA Registration and Why It Matters in the U.S.
In the United States, all pesticide products must be registered with the Environmental Protection Agency (EPA) to be legally used.
Why this matters:
Only EPA-registered insecticides can be used on U.S.-originating flights.
U.S. operators must ensure they’re using approved aircraft disinsection products, or risk regulatory penalties and operational delays.
Top-of-descent sprays are NOT currently registered by the EPA for use while passengers are onboard, limiting their availability in the U.S. market.
At Pilotshq.com, we offer two EPA-registered solutions from Callington—a global leader in aviation-grade chemical products:
For cargo hold aircraft disinsection, used before or after loading.
Both products are non-flammable, WHO-compliant, and approved for use on aircraft.
🇺🇸 Disinsection Methods Allowed Under U.S. EPA Regulations
In the United States, Pre-Embarkation is the only aircraft disinsection method currently approved by the EPA.
This method requires:
Callington Pre-Spray – Applied in the cabin before passengers board
Callington 1-Shot Cargo Hold Spray – Used in the cargo hold before or after loading
Not Approved by the EPA for U.S. Use (Any method with passengers onboard):
Residual disinsection methods
Pre-flight spraying
Top-of-descent spraying
These methods may be approved internationally but are not legally allowed on U.S.-based aircraft without explicit EPA approval.
⚠️ Compliance Reminder:Always verify your destination’s disinsection requirements and ensure you’re using EPA-registered products to remain compliant and avoid delays or penalties.
How to Check Country-Specific Disinsection Requirements
Airlines flying internationally must ensure aircraft disinsection is conducted in accordance with each destination country’s regulations.

What is aircraft disinsection?
Aircraft disinsection is the process of spraying insecticides inside aircraft cabins or cargo areas to eliminate or prevent the entry of insects that may carry diseases or damage agriculture.
Is aircraft disinsection mandatory for all international flights?
No. Disinsection is only required for flights entering specific countries such as Australia, New Zealand, India, and several African and Caribbean nations. Each country has its own regulations.
Who sets the global standards for aircraft disinsection?
The World Health Organization (WHO), International Civil Aviation Organization (ICAO), and International Air Transport Association (IATA) provide guidelines followed by most national authorities.
What methods of aircraft disinsection are approved?
Standard methods include pre-embarkation spraying, residual treatments, cargo hold spraying, and in some cases, top of descent spraying (just before landing).
Are all insecticides approved for use on aircraft?
No. Only insecticides that are aircraft-safe, non-flammable, and approved by aviation authorities and regulatory bodies like the EPA and WHO can be used.
What does it mean if a product is EPA-registered?
EPA registration ensures the insecticide has been evaluated for safety and efficacy and is approved for its specific use in the U.S.—such as cargo or cabin disinsection.
Which Disinsection Methods Are Allowed on U.S.-Based Flights?
The only aircraft disinsection method currently approved in the USA is the Pre-Embarkation Method.
This method requires:
Callington Pre-Spray for cabin treatment before boarding
Callington 1-Shot for disinsection of cargo holds (if applicable)
Residual, Pre-Flight, and Top-of-Descent aircraft disinsection methods (Any method with passengers onboard) are not currently approved for use in the U.S. by the EPA.
How can I find out what disinsection procedures are required for a specific country?
You can check the WHO guidelines, IATA’s Traveler’s Health page, or the official website of the destination country’s Ministry of Health or Agriculture.
What are the consequences of non-compliance with aircraft disinsection rules?
Operators may face fines, delayed aircraft clearance, or even denial of entry if aircraft disinsection requirements are not met upon arrival.
Which aircraft disinsection products are recommended for compliance?
We recommend Callington Pre-Spray for cabin disinsection and Callington 1-Shot for cargo hold treatments—both are WHO-compliant and EPA-registered for use in the U.S.

Used 7 on heavily oxidized Airstream. Sanded off oxidation. Presto changeo, an almost mirror-like finish. Will stick with Nuvite. Important to follow instructional video.
This is an amazing aid to my fisning. Something serious inland fishermen should have. My only regret is that I didn't have this over the last 20 years.
