Carpenter bees get their name from their ability to drill through wood and
nest in the hole. They are worldwide in distribution with 7 species occurring in
the United States.
- Problematic species in this area is the Eastern Carpenter Bee – Xylocopa
- The male has a yellow face.
- The female's is black.
- They can resemble bumble bees, but the upper surface of their abdomen is
bare and shiny black, while bumble bees have a hairy abdomen with at least
some yellow markings
- Bees will scout to select a suitable unpainted, weathered or smooth wood
area to start their gallery. Their drilling creates a near-perfect hole,
approximately 3/8” to ½” in diameter.
- Once inside the wood, the tunnel will typically turn 90 degrees. The
female carpenter bee will tunnel into the wood from 6 " to as long as 4
feet to lay their eggs in "galleries".
- Entrance is usually located on the underside of the wood surface;
including siding, soffits, decks, overhangs, fence posts and window frames.
TThey may also bore in from the side.
- Damage is typically cosmetic, not structural.
