Anyone Speak Carpenter Bee?

If so, I'd like to tell the bees digging in the fascia board on my front porch that the University of Kentucky Entomology Department doesn't think they should be doing that. The entomologists say:

Carpenter bees prefer to attack wood which is bare, weathered and unpainted. Therefore, the best way to deter the bees is to paint all exposed wood surfaces, especially those which have a history of being attacked.

Hmmmm. I haven't noticed the carpenter bees I've seen to have much regard for such entomological assertions. I wonder if entomologists actually study insects anymore, or do they just read books written by other entomologists who may or may not have studied insects? So far this year I have eliminated 11 bees that apparently shouldn't even be there with my trusty Dunlop tennis racket. But every time I get one, two more seem to show up. I wouldn't care, but they're right at the front door! Oh well. If anyone could talk to them for me, please let me know.
