Carpenter Bees

Carpenter bees tend to hover near the eaves of the house or drilling in wood and construct their nests in trees or in frame buildings. While the damage to wood from the drilling activities of a single bee is slight, the subsequent year's broods will expand the tunnel through branching activities, possibly causing considerable structural damage. Carpenter bees do not eat wood but rather excavate tunnels in it for shelter and as chambers in which to rear their young. They usually attack unpainted objects such as doors, windowsills, roof eaves, shingles, railings, telephone poles, and, sometimes, wooden lawn furniture.

• Most of the top of the abdomen of carpenter bees is hairless and shiny black in color.
• Carpenter bees resemble bumblebees in both size and appearance but are not social insects.
• Carpenter bees commonly defecate on the wall or other item directly below openings, causing stains.
