Those large bees hovering near the decks, porches, and fences around your home in Wisconsin? They’re likely carpenter bees. Active during spring and early summer, they carve tunnels in untreated wood to nest. You might even spot piles of coarse sawdust beneath the holes they create, a clear sign of their activity. Unlike honeybees, they don’t form colonies and seldom act aggressively. Male carpenter bees can’t sting, and females usually won’t unless threatened, but their damage is easy to recognize.
Batzner Pest Control specializes in controlling carpenter bee problems before they cause serious harm. Our experienced technicians pinpoint activity, apply targeted treatments, and help protect your wood structures from future infestations.
How Much Damage Can Carpenter Bees Do?
When carpenter bees return year after year to bore into your wood, they can seriously weaken your property. What may seem like small damage at first can quickly escalate. Over time, this structural wear can lead to:
- Weakened Railings: Porch and balcony railings are frequent targets for carpenter bees. As they tunnel into the wood, the railings gradually lose their sturdiness and support, raising the risk of collapse and possible injury if left unrepaired.
- Damaged Steps: When carpenter bees infest wooden steps, they slowly hollow them out from within. Over time, this weakens the structure, and the steps may crack or give way, posing a safety hazard much like loose or unstable railings.
- Compromised Support Beams: Carpenter bees boring into structural beams can slowly erode the integrity of your home’s framework. Without timely treatment, this can cause warping or partial collapse, though visible warning signs often appear before severe damage sets in.
- Distinct Entry Holes: Carpenter bee holes are easily recognized by their smooth, round shape, about the size of a nickel. These openings typically appear in exposed wood such as rafters, eaves, or under decks, where bees begin their nesting tunnels.
- Visible Wood Damage: Evidence of carpenter bee activity often includes small grooves, dashes, or round marks etched into the surface of the wood. Since these bees don’t cover their work like termites do, the markings remain visible and serve as a clear indicator of infestation.
Carpenter bees can quickly damage your property if ignored. Call a bee, wasp, and hornet exterminator at the first sign of trouble. Our trained professionals apply the latest techniques to eliminate these insects safely and keep your home protected from future infestations. We’re here to help whenever you need support.

Identifying Carpenter Bees
Carpenter bees are frequently confused with bumblebees because they share similar characteristics, including fuzzy black heads and round, sturdy bodies. However, a major difference lies in their abdomens: carpenter bees have smooth, shiny abdomens, while bumblebees are completely covered in hair.
These bees prefer untreated or exposed wood, making decks, fences, porches, and sheds common targets. They bore directly into the wood and then follow the grain, creating tunnels that can stay hidden for long periods. Over time, this concealed activity can weaken the wood, often without being noticed until the damage becomes severe.
Unlike other stinging insects, carpenter bees do not create paper nests or dig in the ground. They nest solely in wood, which can threaten the integrity of your property if ignored. Detecting their presence early is crucial to avoiding costly repairs.
What Carpenter Bee Activity Looks Like
Homeowners need to watch for carpenter bee activity. These insects leave visible holes and markings in wood, signaling their presence. Spotting them early can help avoid expensive repairs. Typical warning signs include:
- Visible Holes: Carpenter bee activity often begins with round holes roughly half an inch wide in untreated wood around your home. These openings mark the entry points for their tunnels.
- Wood Shavings: Small piles of sawdust or wood fragments may accumulate on the ground or nearby surfaces beneath the holes, left behind as the bees bore into the wood.
- Fan-Shaped Marks: Semi-circular or fan-like patterns around the hole entrances are a strong sign that carpenter bees are present and actively working.
- Internal Sounds: Faint scratching or buzzing noises coming from inside wooden structures indicate that bees are nesting and moving within the wood.
Understanding the Potential Damage from Carpenter Bees
The damage caused by carpenter bees isn’t limited to visible holes or surface markings. Inside the tunnels, larvae produce subtle scratching noises. Even if you can’t hear them clearly, local birds and other animals are attracted to the sound. They see it as an opportunity for a meal.
Woodpeckers and other wildlife often peck at the wood to reach the larvae, enlarging the holes and worsening the damage. A minor infestation can escalate rapidly if ignored. Prompt intervention protects your home from both the bees and the secondary damage caused by predators.
