Post 'n Beam Carpenter Bees
Looks like the buggers are up to no good again but not just in the siding. We have a post 'n beam home and they have carved perfect circular holes into the beams this time. Does anyone know how far they can eat? I think they may have actually breached the interior walls by going into the side of the beam and then heading toward the house.
Should I just spray bee/wasp killer into the holes? Suggestions are great appreciated including what to fill the holes with.
