Everything I read about bee pheremones from the manufacturers are touting their usefulness in baiting bees into the traps. I'm not building a trap, I'm building a house. I would assume that it is intent agnostic. If it works, for instance that carpenter bees are attracted by carpenter bee pheremone spray, I'll use that to lure them to a new home, not to their death. I mean, I've killed quite a few of them with my But-a-Salt contraption, but then I read that they're super beneficial I stopped doing that. I want them around, but I'd rather them be where I want them. Or at least not in holes in my structural 4x4s.

I do know firsthand that carpenter bees will literally destroy existing structures. The carpenter bee traps work well but it results in bee death from starvation if you don't relocate them daily.
