Aircraft Disinsection in Ontario, CA: Ontario International Airport (ONT)

Ontario International anchors the Inland Empire’s logistics economy, handling freighters, airlines, and corporate traffic east of Los Angeles. If your flight out of ONT is headed to a destination that mandates disinsection, our team completes the treatment on the ramp before passengers board.

If your next departure from ONT 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 ask for 36 to 48 hours of notice at ONT, and scheduled bookings are guaranteed for the departure.

About Ontario International Airport

ONT pairs scheduled airline service with one of Southern California’s busiest air cargo operations, reflecting the warehouse and distribution industry that surrounds it. Its longest runway stretches 12,197-ft, ample for fully loaded widebody freighters departing in summer heat. The field gives operators a less congested alternative to LAX while staying within easy reach of the Los Angeles basin. Freight activity keeps the airport moving well beyond the airline schedule.

On the field at ONT

ONT lies 2 miles east of Ontario, California, 944 feet above sea level. The main runway, 08L/26R, is 12,197 feet of concrete. It is a towered field with a Part 139 airport operating certificate. FBOs serving ONT include Guardian Jet Center; we treat the aircraft at whichever ramp or hangar it is parked on. The treatment is scheduled around your departure from ONT and completed before passengers arrive.

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 ONT, that last port is ONT.

From ONT the requirement is mostly a Pacific one: Australia and New Zealand require disinsection on every arriving international aircraft, and the Cook Islands, Fiji and the Solomon Islands require it too. Many itineraries from Ontario stop in Hawaii, which then becomes the last US port and the place for pre-embarkation treatment; non-stop departures are treated here at ONT. Australia, New Zealand, Chile, French Polynesia appear on the list as well.

The aircraft disinsection process on the ONT ramp

Once the plan is set we work directly with the ONT 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.
