I take the lazy way out with those little puppies. I just "pluck" them through the screen, and hope they land outside...it sometimes takes a number of trys.
I have vent covers on my regular vents. I do the same with those, hoping they land on the roof between the vent and the cover. The next rain should wash those little boogers away.
