Aircraft Disinsection at Portsmouth International Airport at Pease (PSM)
Pease is New England’s classic staging point before a crossing: one of the longest runways in the region, on-field customs, and handling used to transatlantic business aviation. An aircraft staging through PSM for a disinsection destination can be treated here, at the last US port before the flight.
If your next departure from PSM 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. Book 36 to 48 hours ahead for Portsmouth; booked departures are guaranteed for the date.
About Portsmouth International Airport at Pease
Portsmouth at Pease is built for the crossing: a very long former Air Force runway, on-field customs and handlers who see transatlantic business aviation daily. For an aircraft staging through PSM before a flight to a disinsection destination, the treatment happens here, at the last US port, before boarding.
Where the aircraft disinsection requirement comes from
Whatever the destination, the mechanism is the same: the arriving country requires the aircraft to have been disinsected, and pre-embarkation treatment at the last port before that country, performed on the empty aircraft, is a method it accepts. For a non-stop flight out of PSM, that last port is PSM.
Departures from PSM that trigger a disinsection requirement are mostly transatlantic. Italy is the one that catches operators most often, because it applies to aircraft arriving from the United States; Greece joined the list in September 2025, and Greece, Morocco, Egypt, India follow. A non-stop crossing from Portsmouth International Airport at Pease makes PSM the last port before the destination, which is exactly where pre-embarkation treatment belongs.
The aircraft disinsection process on the PSM ramp
Once the plan is set we work directly with the PSM FBO and your crew on access, ramp position and timing. Our technician arrives before the agreed slot, confirms the aircraft is empty with catering and cleaning done, and applies the WHO pre-embarkation treatment through the cabin, flight deck and holds. After the specified rest and ventilation the aircraft is released for boarding, certificate in hand.
