About Carpenter Bees

Carpenter bees (Xylocopa spp.) are large, black-and-yellow bees, often mistaken for bumblebees. Unlike bumblebees, they have shiny, hairless abdomens. Females bore round holes into bare or weathered wood to create nesting tunnels.

Risks & Concerns

Over time, repeated nesting weakens wood structures, especially decks, railings, and siding. While females can sting if provoked, they are usually not aggressive. Males hover near nests but cannot sting.

Prevention & Control

Paint or seal exposed wood to discourage nesting. Fill old holes with wood putty. Professional pest control may be needed for persistent activity.
