While the flame thrower idea would seem to solve a lot of issues at once, I don't have enough time to move all my valuables out of the house, and I assume the fire department would think it was suspicious that all our stuff was out on the lawn. The tennis racket is fun and great for working on the backhand form, it's not doing much good. I believe only the females can sting, and they are not as common to see out flying around. Probably in the hole making babies and sammiches...Carpenter Bees (aka the Incredible Bee Hullks) are amazingly resistant to consumer-available insecticides. I've hit them with direct streams of wasp & hornet spray and they just slow down a little in flight due to the momentum of the fluid. It apparently has no immediate toxicity for them.
I recommend:
1. The flamethrower idea
2. Baseball bat
3. Hammer
4. Biga** medieval two-handed sword
5. .308 or bigger
On the bright side, if they can sting, they don't seem to be inclined to do it much. They just kind of lumber along and eat your stuff.
