Meet the Woodworking Bee That Drills Holes and Doesn’t Sting

Carpenter bees might not wear tool belts like real carpenters, but they do have impressive woodworking abilities thanks to their strong jaws. The jaws of this bee are strong enough to drill perfect holes into wood. In a way, they are like tiny construction workers. The real builders among the woodworking bees are the females. Using their mandibles, females create long nesting tunnels for their future offspring. This extraordinary ability to carve structures with their mandibles might make you wonder: what is stopping them from doing the same to us? After all, wood is much tougher than flesh. This leads to the question: Should we be afraid of carpenter bees?

Woodworking Bees

Carpenter bees belong to the genus Xylocopa, a name derived from Greek: “xylo” means wood, and “kopos” means cutter. This is a fitting description for what these bees do. Carpenter bees are often mistaken for bumblebees because of their fuzzy appearance. This is an easy mistake since they are roughly the same size, make similar loud buzzing sounds, and hang around flowers. The easiest way to tell carpenter bees from bumblebees is by their nesting behavior and certain details of their appearance. Carpenter bees have a smooth, shiny abdomen, while bumblebees can look fuzzy all over. In addition, carpenter bees are solitary, meaning each female builds and maintains her own nest, unlike bumblebees, which are social and live in colonies. Therefore, these bees do not live in large hives like honeybees or bumblebees.

You can usually spot where a carpenter bee is drilling into wood by the small piles of sawdust it leaves behind. Each female is responsible for making and maintaining her own nest. The female carpenter bee does all the digging, egg-laying, and sealing. Male carpenter bees do not help with the nesting process, nor do they have stingers like the females, but they are still pretty territorial. They can often be seen buzzing around nest entrances, sometimes even buzzing in your face. Here’s the catch: male carpenter bees do not have a stinger, so their aggressive buzzing is just for show.

The female carpenter bee acts as the worker, protector, architect, and caretaker—all in one black and yellow buzzing package. Using her mandibles, the female carpenter bee chews entry holes into untreated or weathered wood to create a nest for her offspring. These tunnels can range from several inches to several feet in length. Within each tunnel, there are multiple cells, each containing an egg. To supply the egg with a food source when it hatches, females create a “bread” mixture. This bread mixture is made from regurgitated nectar and pollen. Once this mixture is placed with the egg, the female seals off the cell with chewed wood pulp. Because the tunnel-making process is labor-intensive, these cells are often reused by future generations.

Do Carpenter Bees Sting?

The fuzzy insects that try to dive-bomb your face during the summer are usually male carpenter bees. Fortunately, male carpenter bees do not have the tools to sting you. Only female carpenter bees can sting, and they rarely do. Even though they have powerful mandibles, these are for woodworking, not defense.

Female carpenter bees generally sting when they feel threatened. Most of the time, females are too busy drilling holes and tending to their offspring. In other words, they do not care much about you (unless you stick your finger in one of their tunnels, of course). It’s ironic that the males appear and act much more aggressive, yet they cannot sting at all. They often fly aggressively at you, hover near your head, or buzz a little too close for comfort, but that’s all it is—a buzz. Overall, carpenter bees are much less likely to sting than other flying insects like wasps or yellowjackets, which tend to be more reactive and territorial.

What Can Carpenter Bees Actually Harm?

The real concern when it comes to carpenter bees should not be your skin; it is your wood. Female carpenter bees have a preference for the type of wood they choose to drill holes into. For the most part, these bees drill into wood that is exposed, untreated, or weathered. So, when it comes to older fences, railings, window sills, and decks, they are all fair game to these drilling bees. Though a single tunnel might cause mostly cosmetic damage, over time (especially if bees return each year), this can lead to structural weakening. Carpenter bees usually avoid painted or sealed wood. Although it is rare, there is still potential for them to drill in these areas.

When it comes to people and pets, the threat of carpenter bees is pretty low. Woodpeckers drill holes into these tunnels in search of food items like insects. This further drilling can contribute to even more damage. These bees rarely sting. Unless someone actively disturbs them or their nesting tunnel, they typically will not bother you. So, are carpenter bees something to fear?

Appreciating Carpenter Bees

Yes, carpenter bees can cause damage if left unchecked, but that is after years of activity. They might seem like a nuisance, but they are mostly harmless and even helpful. These bees are pollinators, and while they are not as efficient as other native solitary bees, they still play an important role in fertilizing flowers, fruits, and crops.

In native ecosystems, carpenter bees help keep plant life thriving. The nesting holes eventually become part of a larger ecological cycle. Birds like woodpeckers use carpenter bee holes to find food, and spiders use the holes for protection from predators and as resting spots during the day. These things are all connected, and carpenter bees help create these ecosystem services simply by doing what they naturally do.

If you still do not love the idea of woodworking bees nesting near your home, here are some safer solutions than panic and pesticides.

1. Try using natural deterrents like citrus sprays or almond oil, or plug old carpenter bee holes with wood putty.

2. Installing bee blocks or bee houses in areas away from your porch gives them another place to go that is not your house.

The point is, you are not fighting against these natural workers of the ecosystem; you are simply offering them an alternative.

Gentle Builders in a Noisy World

The loud buzzing and drilling into wood may make carpenter bees seem threatening, but they are more misunderstood than menacing. The truth is, these bees are not out to get you (despite buzzing in your face); they are just doing what nature intended them to do. Female bees rarely sting unless provoked. Male carpenter bees might buzz at you, but they cannot sting at all. The damage these bees cause is typically slow to develop, localized, and can be avoided with proper prevention. With some prevention and understanding, these creatures can become curious neighbors, building a family rather than being a nuisance.

Carpenter bees pollinate, build, and contribute to a healthy ecosystem. Even though they provide these benefits, carpenter bees are threatened by habitat loss and pesticides. Learning more about these creatures and the ecosystem services they provide can help us build a better future for them. Genuinely, there is no reason to fear these wood-carving bees (unless you are allergic). Planning ahead, respecting their space, and possibly even taking a moment to admire their crafty capabilities can go a long way. After all, there is something beautiful about the legacy they leave in the drilled wood behind them.
