TLDR: Carpenter bees have shiny, black abdomens and bore holes into wood. Honey bees have fuzzy, striped abdomens and live in hives. If you see round holes in unpainted wood with sawdust below, you have carpenter bees. Honey bees should be relocated by a beekeeper, not treated. For carpenter bee damage, paint exposed wood, fill old holes, and call a professional if tunneling is widespread.
When you see bees buzzing around your home, the first step is knowing which type you have. Honey bees live in large colonies and don’t damage your home. Carpenter bees bore into wood to nest and can cause real damage over time. Each needs a different response.
As a licensed technician since 2015, I’ve helped families across the DMV area deal with bee problems. Our family business has served this region for over 57 years. The most common mistake we see is homeowners treating the wrong bee, which wastes time and money.
How to Tell Honey Bees and Carpenter Bees Apart
The fastest way to ID these bees is by looking at their abdomens. Honey bees have fuzzy, striped abdomens with golden-brown bands. Carpenter bees have shiny, black abdomens that look almost bald.
Size helps too. Carpenter bees measure about one inch long. Honey bee workers are about half that size.
Male carpenter bees have pale-yellow faces, while females have all-black faces. Both sexes have fuzzy yellow mid-sections, but that shiny black abdomen is the key giveaway.
Key Physical Differences
| Feature | Honey Bee | Carpenter Bee |
|---|---|---|
| Abdomen | Fuzzy, striped | Shiny, black |
| Size | About 0.5 inches | About 1 inch |
| Social Structure | Colony (thousands) | Solitary |
| Nesting | Tree cavities, hives | Bore into wood |
| Property Damage | Minimal | Wood damage over time |
How Each Bee Behaves
Male carpenter bees hover near eaves and wooden structures, especially in spring. This looks threatening, but male carpenter bees cannot sting. Female carpenter bees can sting but rarely do unless you handle them directly.
Honey bees fly straight between their hive and food sources. They don’t hover around your home the way carpenter bees do. Honey bees only sting when their hive is threatened, and their barbed stinger stays in your skin, which kills the bee after one sting.
Female carpenter bees are the ones that do the drilling. You may hear them working inside wood on warm spring days. The round holes they leave behind are the clearest sign of carpenter bee activity.
Where Each Bee Nests
Honey bees build hives in tree cavities, wall voids, or managed beehives. They make wax combs inside their hive and live in colonies of thousands. They rarely cause structural damage to homes.
Carpenter bees bore directly into wood surfaces, making perfectly round holes about half an inch across. Females drill tunnels that can reach several inches deep. These tunnels are where they lay their eggs. Common targets include deck railings, eaves, siding, and outdoor furniture.
The University of Maryland Extension reports that carpenter bees prefer unpainted, weathered wood for nesting. USDA research notes that honey bees pollinate over 100 agricultural crops and contribute about $18 billion per year to U.S. agriculture. Carpenter bees use “buzz pollination” to shake pollen loose from flowers, which helps crops like tomatoes, eggplants, and blueberries.
A single carpenter bee tunnel rarely causes structural problems. But multiple generations can reuse and expand the same tunnels over many years. This creates networks that weaken wood. The damage gets worse when moisture seeps into the holes and when woodpeckers tear into the wood looking for larvae.
Signs of Carpenter Bee Damage
Carpenter bees become a problem when their tunneling threatens your wooden structures. Watch for these signs:
- Round holes in wood about half an inch across, especially in unpainted or weathered surfaces
- Sawdust piles below wooden structures or furniture
- Males hovering near eaves and decks during spring
- Dark stains around hole entrances from bee droppings
- Woodpecker damage near bee holes, as birds dig for larvae
How to Get Rid of Carpenter Bees
Keep all exterior wood painted or stained. Carpenter bees avoid treated wood. Pay extra attention to eaves, deck railings, siding, and outdoor furniture. This is the single best prevention step.
After activity stops in fall, plug old holes with steel wool and wood putty. This prevents new bees from reusing the tunnels the following spring. Replace wood that’s heavily damaged.
Apply approved insecticide dust directly into active tunnel openings during spring when bees are nesting. Wait a few days for the product to work, then seal the holes. For large infestations, a licensed technician can treat hard-to-reach areas.
Check for new holes each April and May when carpenter bees start nesting. Early treatment prevents tunnel networks from growing. A tri-annual pest control program covers this along with other seasonal pests.
What to Do About Honey Bees
Honey bees should be relocated, not treated with pesticides. They don’t damage wood and their colonies are important for local food crops. If you find a honey bee hive or swarm on your property, contact a local beekeeper for relocation.
If a honey bee colony has moved into a wall void or another spot that causes problems, a beekeeper can often remove the colony alive. Only call a pest control company for honey bees if relocation isn’t possible and the colony poses a direct risk to people.
Carpenter Bee vs Bumble Bee
Many homeowners also mix up carpenter bees with bumble bees. Both are large, but the abdomen tells the story. Bumble bees have completely fuzzy abdomens like honey bees. Carpenter bees have that shiny, bald-looking abdomen.
Bumble bees nest underground or in small cavities and don’t damage wood at all. If you see a large fuzzy bee coming out of a hole in the ground, that’s a bumble bee. If it’s coming out of a hole in your deck, that’s a carpenter bee.

Seasonal Patterns
Carpenter bees are most active from April through June. Adults come out of overwintering spots to build new nests. This is when you’ll see the most hovering from males and hear drilling from females. New adults emerge in mid-summer, then find spots to overwinter in late fall.
Honey bees stay active through most of the year. Peak swarming happens in April and May in the DMV area. A swarm on your property is usually just a temporary stop while scouts find a permanent home.
The best time to treat for carpenter bees is late winter or early spring, before new nesting begins. Treating after emergence catches bees before they can drill new tunnels.
Most bee calls we get in spring are about carpenter bees hovering near decks and eaves. Homeowners worry about getting stung, but the hovering males can’t sting. The real concern is the females drilling into wood behind the scenes. Painting exposed wood is the simplest fix I recommend, and it prevents most carpenter bee problems before they start.
When to Call a Professional
Some bee situations need expert help. Call a licensed technician if:
- You see carpenter bee holes in more than one area of your home
- Tunneling has been going on for multiple years
- You can’t reach the affected wood (high eaves, soffits)
- You’re not sure which bee species you’re dealing with
- Woodpeckers are making the damage worse
Our technicians start with a full inspection to identify the bee species and check the extent of any wood damage. We use targeted treatments in active tunnels and can repair or replace damaged wood. Our carpenter bee damage assessment helps you understand what needs fixing.
At Better Termite & Pest Control, we’ve handled bee problems across Alexandria, Fairfax, Bethesda, and the DC metro area for over 57 years.
