Getting Rid of Bees' and Wasps' Nests

Go out at night after all the bees/wasps have gone to bed.  Take a can of Raid -- the black label with the big black nozzle for "Wasp and Hornet" -- and maybe a pair of garden or oven gloves just so you don't get the spray on you.  Also take a flashlight.  Get to within 10-15 feet of the nest, shine your light on the hole at the bottom of it, and spray away.  Then spray the whole nest.  In the morning, go and have a look.  Without the constant rebuilding of the wasps, the walls of the nest will have already begun to flake off and float away in the morning breeze and the whole structure will begin to look skeletal -- a lost civilization.
