I Hate Insects

I bought an electric bug killer from Lowes yesterday. We have about 20+ wood bees that are destroying our wooden hand rail. The females eat an amazingly round hole in the wood, normally on the underside. The mails then "guard" the female who pretty much remains inside the wood. The males are a pest (look like bumblebees) the killer looks like a tennis racket, but with wire mesh instead of the normal plastic face. It is battery powered and as you swing the racket you push a button which electrifies the wires. When you hit them they get fried.
We got all but one of the males last night. If they are gone then the females generally die as there is no one to guard or feed them.
Anyone else have bug issues, this is an inexpensive way to eradicate the problem.
