Damage From Carpenter Bees

Carpenter Bees make round tunnels in wooden structures where they shelter and raise their young. They do not feed on the wood, but over time the tunnels can damage the integrity of the wood and structures it supports.  

Carpenter Bees can damage decks, posts, beams, siding, rafters -  any exposed wood. Carpenter Bees prefer unpainted wood.
