I hate the little beggars! We are beset by them every year. They try to take over my greenhouse, and the barn and get into the roof of our gazebo, and if you get too close to where they have their nests, they get pretty obnoxious. I've never been stung by one, tho. Heh, heh, I have discovered that a spray bottle of rubbing alcohol will take them out very nicely, thank you.
