Michael Petruccelli asks; How do you identify, treat and prevent Carpenter Bees? (2)

Michael Petruccelli says; About carpenter Bees – They bore perfect round holes in which the females will deposit their eggs. They bore into unprotected or unsealed wood and use the cavity as a “nest”. The sawdust coming from the hole is called “frass”. The bees produce a yellow-or-brown colored dropping that secretes out of the bored holes and stains the wood.
