If you've flown internationally for while you probably have some experience with having to spray the aircraft before beginning descent or even having to spray the aircraft after arrival and then having to seal the cabin for ten minutes as the passengers look at you with accusing eyes. "Couldn't you have gotten us out of this, captain?" In my charter GV years we had flight attendants keep a supply of half-spent spray cans so they could spray the entry door into fooling the inspectors that the cabin had been sprayed. I'll leave the ethical questions to you. For me, I don't like having aerosols on the aircraft so I would just assume have the inspectors bring the spray and let them spray. Australia may be my favorite country on earth and it seems like a small price to pay, mate.

If you want to buy the spray ahead of time, I've never found a good option in the United States. The vendor of choice is Callington, based in Australia, but they are not allowed to ship to the United States. If you look around you can find vendors in Canada, the United Kingdom, and many places in Asia and the Pacific. Some FBOs keep large quantities on stock and many operators buy cases when overseas. But this isn't very wise, in my opinion. I don't think these cans have been tested under the conditions of a rapid decompression and having a case of the stuff explode at altitude would be bad news.

You might be able to fumigate the aircraft at your home base and have that count for your arrival, a process called "residual disinsection." The unknown is how do you document that so the country you are travelling to will buy off on it? You should first see if the country will allow it and how they want it documented. If they say okay, you should contact your aircraft manufacturer for procedures on how to do this correctly.

There have been news reports that Italy is now requiring disinsection of all incoming aircraft, regardless of origin, in response to the Zika Virus. As of 16 Feb 2016, the NBAA says Italy is requiring a certificate of disinsection or they will spray upon arrival. More about this: https://www.nbaa.org/ops/safety/20160216-some-countries-requiring-mosquito-treatment-for-business-aircraft-in-wake-of-zika-virus.php. Two readers provide first hand reports.

Italy, First-hand Report


I see you have some new info on disinsection in your “updates”. I can provide some first-hand knowledge into the requirements in Italy, as I was disinsected twice this month at Ciampino. We were required to provide a certificate with “our airport’s medical officer’s WHO stamp”. Huh? We elected to have it done on arrival at LIRA, and it wasn’t a big deal. Passengers were offloaded, we removed our bags, cleaned up the airplane (G550) and waited for the sprayer. It was done with a pump sprayer of the type you’d spray your fruit trees. He was very careful, sprayed just on the carpet, wiped up any overspray, and stayed out of the cockpit area. The airplane had to be then closed for 1.5 hours, but we just closed it up and went to the hotel. Three days later we opened up the door to start our departure day, and it really didn’t seem to have much odor, and any that lingered was quickly dispersed with the open MED and baggage door. It is recommended to run the A/C packs for at least 30 minutes before closing up for departure. Total cost was 569.80 Euros, including the certificate, which is good for 8 weeks.

Hi Eddie,

We had a recent trip into Milan, Italy – LIML. Here’s what we experienced concerning the “Residual Disinsection” requirement.

In Geneva, after the pax left and we were ready to leave for the hotel (one RON), two men came to do the spraying. Actually, one held a clipboard outside, while the other donned a white jump suit and began to spray the cabin and baggage compartment with a small aerosol can of “FLYMED AIRCRAFT”. Then the aircraft was closed up and we departed. I believe the plane must stay closed up for one hour. I asked for a certificate of the spraying, but I was informed that it would have to be sent to our home operations. The certificate arrived about 10 days later. The fee was billed through our handling agent, Universal. That charge was about $400 US.

Get this: All aircraft coming from ANY country must be sprayed or have been sprayed within the last 8 weeks. This includes Italy. Thus, if you’re up in Rome and were OK at that time, but them fly to Milan and your eight weeks has expired, you must get sprayed again. I have no idea what would be the protocol if after landing in Milan, we then went to Rome and had no certificate.

BTW, we removed all food items, even packaged goods such as peanuts, etc.

Upon departure day, we opened the aircraft (it had been about 18 hours shut up) and the smell of the insecticide was very strong. It caused me to cough a lot. The aircraft must be aired out for at least 30 minutes, but I’d recommend one hour.

The World Health Organization says disinsection sprays are not hazardous to your health. You may or may not believe them, there are a number of sources that back them up:

On the other hand, a study by the American Journal of Industrial Medicine conducted a study of several reports of flight attendant illness over a 1-year period and concluded:

The 12 cases of pesticide illness documented in this investigation demonstrate that Residual insecticide applications can result in illness among workers exposed to the aircraft cabin environment after disinsection. The documented acute illnesses likely underestimate the magnitude of illnesses due to disinsection. The public health impact of Residual disinsection also includes other workers who pilot, clean, service, and maintain the aircraft, and the passenger population. The conditions of use (i.e., the aerosol application of a pesticide in a confined space) significantly contributed to the human health hazard of Residual disinsection.
