About Carpenter Bee
Carpenter bees (Xylocopa spp.) are large, robust bees measuring 19–25 mm that closely resemble bumblebees but have a glossy, hairless black abdomen. Females excavate perfectly circular 12 mm entrance holes into unpainted or weathered softwood — cedar, pine, and redwood siding — and bore galleries up to 30 cm deep to rear young. Males patrol aggressively but lack stingers; females rarely sting unless directly handled. Over many seasons, returned females extend existing galleries, and accumulated structural damage can become significant. Yellowish frass and wood shavings beneath drill holes are the primary signs of active infestation.
Geographic Distribution
