Carpenter Bees are large, black bees that hover outside of homes and under eaves in the late spring and early summer. They are similar in appearance to bumble bees, but the Carpenter Bee has a bare and shiny black abdomen instead of a hairy, yellow-marked abdomen. Although they are similar in appearance, they behave differently. Instead of nesting in the ground, Carpenter Bees tunnel into wood to lay their eggs. They prefer bare, weathered, and unpainted wood, and common nesting sites include eaves, window trim, siding, decks, and outdoor furniture. Damage to wood may be extensive if bees have been nesting there for more than one season.
Although Carpenter Bees are less aggressive than wasps, they still sting, especially when provoked. Treatment for Carpenter Bees is best left to a professional.
