Carpenter bees drill perfect round holes into unfinished wood decks, fences, eaves, and siding. Left untreated, the damage compounds year over year. XtermaPro treats existing nests and helps prevent future damage.
Carpenter bees look similar to bumble bees but have a shiny, hairless abdomen. Unlike bumble bees, they are solitary each female drills her own tunnel into bare wood to lay eggs. They prefer unpainted or weathered softwoods including cedar, pine, and fir. The same sites are reused and expanded each year.
Carpenter bee activity signs:
A single carpenter bee tunnel is a minor issue. But the same galleries are expanded and reused annually, and woodpeckers aggressively excavate the wood to reach larvae resulting in significant structural damage over time. Decks, pergolas, fascia boards, and window frames are commonly damaged.
We treat active galleries with professional-grade insecticide dust, which is slow-acting and contacts bees as they move through their tunnel. After treatment, holes are sealed to prevent reuse. We recommend painting or staining bare wood as the most effective long-term deterrent.
