Blow torch works well, too, trust me!
Believe I read that while they seem more aggressive, the lower overnight temps in the Fall affect their little brains (like a brain freeze) making them less cognizant of surroundings. They initiate closer contact to food, etc. with less apprehension, and the resulting behavior puts them in closer contact. Hence, more stings.
And blow torches work too.

'round about 10 PM I cut a square of porch screen and placed it over the hole using three small pieces of lumber to hold it in place. I then poured gasoline in the hole and watched the little suckers die, die, die. It was beautiful, in a sadistic sort of way. My only concern with this method is that the hole is near a leland cyprus that I like; I'm hoping the gasoline doesn't contaminate and kill/injure the tree. I'm going to go flush the hole out with the hose and try to dilute the affect of the gasoline.
I kept the screen over it all night. Just checked it this morning and there are no survivors...ducks, dogs, and children are now safe from that nest. The hole was huge, like the size of a baseball.
