The hardware store will sell you an aerosol can of wasp and hornet killer. It has a special nozzle that shoots a straight stream about 30 feet. You have your choice of products with different main ingredients, either petrochemical or "natural". The "natural" one is concentrated oil of spearmint (yes really!) and it works fantastically well. When I sprayed a yellow jacket nest under the eaves of my house, the little bastards fell straight to the ground, writhed around for 90 seconds, and expired. One microsecond after the spray touched them, they lost the ability to fly (and thus to travel the 26 feet of distance between their nest and my body). Not only do you get to stomp the crap out of nearly-dead yellowjackets, but your boots will smell minty fresh for days afterwards.
