Sounds like you enjoy wood bees. They can be worrisome and a nuisance. They don't sting to my knowledge. I tried several things. Yours nouns mad because you stopped up their holes to their homes. I watched and when some go in the holes I sprayed them with wasp contract killer and then sprayed all the other holes I could find. No more bees for me and they be in a horse barn and aggravating the animals to death beside their constant buzzing.
