Carpenter bee control in Western North Carolina
Serving Asheville, Brevard, Cashiers, Hendersonville, Waynesville & Surrounding Areas
If you've got large bees hovering around your porch, deck, or eaves in spring, dive-bombing anyone who gets too close, you're probably dealing with carpenter bees.
They're one of the most common pest complaints we hear from homeowners across WNC — and while they look intimidating, the real problem isn't the dive-bombing. It's what they're quietly doing to the wood on your home.
Pisgah Pest Control has been helping homeowners across Asheville, Brevard, Hendersonville, Waynesville, and Cashiers deal with carpenter bees for over 50 years. We know where they nest, what damage to look for, and how to treat them properly before that damage adds up.

Why carpenter bees are so common in WNC
Western North Carolina's older housing stock, abundance of natural wood, and wooded surroundings make it prime territory for carpenter bees. They're drawn to unpainted or weathered softwoods - the kind found in older decking, fascia boards, window trim, pergolas, and wooden outbuildings that are common across the region.
Activity picks up significantly in spring as temperatures rise and carpenter bees emerge to mate and establish new nesting galleries. The hovering and dive-bombing that homeowners notice is almost always male carpenter bees being territorial - they look alarming but don't actually have a stinger. It's the females doing the drilling that are worth paying attention to.
Wood most commonly targeted in WNC homes
- Decking and porch fascia boards
- Roof eaves and soffits
- Window and door trim
- Wooden fence posts and railings
- Pergolas, gazebos, and outdoor furniture
- Barns, sheds, and outbuildings with unpainted wood
What carpenter bees actually do to your home
Carpenter bees drill near-perfect circular holes, roughly the diameter of your finger, into wood surfaces to create nesting galleries. The entry hole goes straight in for a short distance before turning to run with the grain of the wood, sometimes extending several inches or more - and existing galleries get reused and extended year after year.
On their own, a few galleries aren't a structural crisis. But left untreated over multiple seasons, the cumulative damage to fascia boards, eaves, and structural trim can become significant and expensive to repair. The other issue is woodpeckers - they're attracted to carpenter bee larvae inside the wood and will aggressively peck into the same boards to get at them, accelerating the damage considerably.
How to tell if you have carpenter bees
- Perfectly round holes, roughly half an inch in diameter, in wood surfaces around your home
- Coarse sawdust beneath entry holes, often on decking or the ground below fascia boards
- Yellow pollen and excrement staining below entry holes
- Large, robust bees hovering persistently around the same area of the house - particularly in spring
- Woodpecker activity on wooden eaves or fascia, which often indicates an active carpenter bee infestation underneath
Carpenter bees are often mistaken for bumblebees since they're similar in size. The key difference is the carpenter bee's abdomen — it's smooth and shiny black, while a bumblebee's is fuzzy and yellow.
Frequently asked questions
Are carpenter bees dangerous?
The large bees hovering around your porch are almost always males, which don't have stingers and can't sting. Female carpenter bees do have stingers but are docile and very unlikely to sting unless directly handled. The real concern with carpenter bees isn't the sting risk - it's the structural damage they cause to wood over time.
How do I know if it's a carpenter bee or a bumblebee?
Size-wise they're similar, but the carpenter bee has a smooth, shiny black abdomen while a bumblebee's abdomen is fuzzy and yellow. If you're seeing large bees hovering persistently around the same spot on your eaves or decking, and there are round holes in the wood nearby, it's almost certainly carpenter bees.
How much damage can carpenter bees cause?
A single season of activity causes limited structural damage. The problem builds over multiple years as galleries are extended and reused, and as woodpeckers move in to access the larvae inside the wood. Fascia boards and eaves in particular can take significant damage over time if the problem isn't treated.
Will painting my deck or fascia stop carpenter bees?
It helps significantly. Carpenter bees strongly prefer bare, weathered softwood and are far less likely to drill into painted or stained surfaces. It's one of the most effective preventative steps a homeowner can take, and we'll always recommend it alongside professional treatment.
When is the best time to treat for carpenter bees in WNC?
Spring is the most effective treatment window, when carpenter bees are actively emerging and establishing new galleries. Getting treatment in early in the season prevents new damage from being added and addresses the current year's population before it gets established.
Why do carpenter bees keep coming back to the same spot every year?
Carpenter bees are strongly attracted to existing galleries, both their own and those of previous generations. An untreated entry hole is an open invitation for reuse the following season. Sealing galleries after treatment is an important step in breaking that cycle.
