As nice is it is to just spray something on a bee wasp or whatever so its wings melt/gum up or whatever. Just remember that guy will still sting you even crawling around if he gets the chance.
I must have killed a thousand wasps one summer painting houses. Usually every house would have at least one wasp nest (usually no bigger than your fist) somewhere under the eaves etc. I got pretty good at doing the lit aerosol can flamethrower thing which if done right would singe at least enough of all the wings of the wasps and you would see them drop like rocks to the ground.
There was always the occasional missed wasp, which usually happened when you were doing the routine on a high ladder, but hey we had to get the houses painted and knocking the nest down and coming back the next day was not an option.
But I can remember that those wasps would still crawl around and one stung me on the butt while I was eating lunch. O well.
I worked in a machine shop when we learned to use Gunk... At first we tried WD40 and a lighter, but that was really too dangerous, what with solvent tanks and parts washers around. The Gunk kills the critters within about 5 minutes or so, sometimes less, depending on how much of the stuff you hit them with. It also dissolves the exoskeletons, but not as fast as the wings.
