The carpenter bees are doing a number on our house! We perfectly fit the profile of a desirable place to lay your eggs for this rather docile bee, and they are busy around the frame of the garage as I write. I do have a plan.
Carpenter bees are essentially harmless. The male, who hovers about, has no stinger. The female tunnels and lays her eggs. When she does come out, you would have to handle her for her to sting.
I’ve never been stung by one and they sort of become acquaintances, because they are always there hovering about.
