Thanks for all of your replies
I didn't think this would be such a wide-spread practice, and I don't understand how a flight crew can deal with so much spraying all the time (even the pre-impregnated veriety)... The cabins of these airplanes must be toxic to some extent also for humans, I imagine. Aren't there any complaints about how the pesticide adversly affects crew's health or is the pesticide really fully harmless to people?
Now that it comes to my mind.. This requirement for pesticide must also be required for ships that come to your countries, right? I wonder how many cans are necessary for
that !
And by the way, could someone please give me some links to Aus/NZ aviation forums as I mentioned before?
Thanks, Marco
