wasp nest in aileron

At this time of year the wasps start a nest in my ailerons a couple of
times each week. I'm allergic to wasps so each time that I go out to the
airport I look for the newly started nests and spray them with Raid
flying insect killer. Obviously to do this involves spraying the insect
killer inside the aileron and it just ocurred to me that I don't know
whether or not this stuff is corrosive. Anyone know? Anyone got any
other suggestions for getting rid of them? Flying with them in the wing
is not an option. If the find their way into the cockpit I'm in trouble.

Thanks
