Carpenter Bees
NuisanceWhat it is
Large solitary bees that bore round nesting tunnels into unfinished or weathered wood. Males may hover defensively but cannot sting; females can sting but usually do so only when handled or threatened.
How to recognize it
Large bees like bumble bees, but with a shiny, hairless abdomen. Perfectly round holes in wood with sawdust below.
Where you will find it
Eaves, fascia, decks, railings, and unpainted or weathered wood.
Why it matters
Repeated nesting enlarges the tunnels and can damage wood over time. Males hover aggressively but cannot sting.
What to do
- Do not pick at, drill, or disturb damaged wood. Photograph it, and note any sawdust, mud tubes, or exit holes.
- Report leaks and damp areas, since moisture attracts many wood-destroying insects.
- Contact a licensed pest professional for an inspection to confirm what is active.
- Avoid spraying. Surface sprays do not reach nests inside wood or soil.
When to call a professional
- You see swarmers, mud tubes, sawdust piles, or round exit holes in wood.
- Wood sounds hollow or feels soft.
- You are buying or selling a home.
