I think that you first need to determine just what you are dealing with. Were they bees or hornets? Maybe yellow jackets or wasps? Or were they some diabolical creatures from outer space? Some times actual HONEY BEES will make a home between clapboard siding and the inner walls of a home. It is unnecessary to destroy them, as there are beekeepers who if contacted would come and extract them. Bees are beneficial insects, and if they sting you they die. If you are stung by a bee flick the stinger that is left in your skin off with your fingernail.Do not grab it with a pinching maneuver, or you will inject what ever venom that remains in the sack into you.In the wasp family there are wasps, hornets, and yellow jackets that can sting multiple times, and as far as I am concerned, should be eliminated by using a spray that you can hit them with from about 10 feet away. I used to hit paper wasp nests with an aerosol that made them drop dead, and as they dropped, I thought that they were still after me, but they passed right by and hit the ground dead. There is another wasp type that you might encounter that looks very wicked, but is harmless, and it is called a Cicada killer. They prey on the Cicadas that you hear in mid-summer. Hope this helps, but if they are bees, please don't kill them, kill the wasps. Happy painting Paul.
