Aircraft Disinsection at Seattle-Tacoma International Airport (SEA)
Seattle-Tacoma International is the Pacific Northwest’s long-haul gateway and hosts long-range business aviation departures. Pacific private flights leave from SEA year-round.
If your next departure from SEA is to a country that requires disinsection, we come to your aircraft here, treat it empty before boarding to the WHO pre-embarkation method, and issue the certificate for the flight. We typically reach SEA within 24 to 36 hours of confirmation, and scheduled bookings are guaranteed for the departure.
About Seattle-Tacoma International Airport
Seattle-Tacoma International is the Pacific Northwest’s long-haul gateway and hosts long-range business aviation departures when the aircraft needs its runways or customs infrastructure. Pacific private flights leave from SEA year-round.
Where the requirement comes from
No US authority requires disinsection on departure. The obligation is created by the arriving country, which expects a treated aircraft and a certificate. Pre-embarkation treatment performed at SEA, the last port before a non-stop international arrival, is how operators meet it without spraying an occupied cabin at the far end.
From SEA the requirement is mostly a Pacific one: Australia and New Zealand require disinsection on every arriving international aircraft, and the Cook Islands and Solomon Islands require it too. Many itineraries from Seattle stop in Hawaii, which then becomes the last US port and the place for pre-embarkation treatment; non-stop departures are treated here at SEA. New Zealand, Cook Islands, Chile appear on the list as well.
How it works on the SEA ramp
On the day, the sequence at SEA is simple: our crew is at your hangar or FBO ahead of time, the cabin is confirmed empty and prepared, the treatment is applied to the WHO method through cabin, flight deck and holds, and the aircraft rests, ventilates and is released for boarding after the required wait. Your crew receives the certificate and the details to enter on the General Declaration before the door closes.

Can you get to SEA on short notice?
Often, yes. We travel to Seattle from our base and handle our own logistics; the earlier we hear about a likely trip the more precisely we can time the treatment, but short-notice requests are a normal part of the work.
What if our routing has a stop after leaving the US?
Pre-embarkation covers the flight it is performed for and is done at the last port before the destination country. Send us the full itinerary and we will tell you exactly where the treatment belongs.
