As with many bee species, carpenter bee sociality varies. Some carpenter bee species are solitary, meaning that the bees only interact during mating, while others are communal, meaning that they nest and live together in colonies.
Some species of carpenter bees, such as the Eastern Carpenter Bee (Xylocopa virginica) in the United States, are known to form nesting aggregations, where several females will share a single, common nesting area, but will create their own individual, separate galleries inside of it.
On average, a communal nesting aggregation can have anywhere from 20-100 female bees. Additionally, some species of carpenter bees are semi-social, which means that they can either behave as solitary individuals or live in small groups.

Why are there so many carpenter bees around my house?
Carpenter bees are often drawn to certain types of wood around homes, particularly unpainted or stained softwoods like redwood, cedar, cypress, pine and douglas fir. These wood types are attractive to carpenter bees as they are easy to drill and nest in.
Additionally, carpenter bees are naturally drawn to areas that provide shelter, such as a sunny, hollowed out space near the base of your house or along the eaves where they can remain undisturbed. With the availability of wood and protection from the elements, these areas become popular breeding grounds for carpenter bees.
It is also possible that carpenter bees have decided to use the area around your home from previous generations. The inside of trees and old, abandoned nests may attract female carpenter bees to lay their eggs and begin the cycle anew.
Therefore, if you have had problems with carpenter bees in the past, more carpenter bees may be attracted to the area because nests have been left behind for them to make use of.
Understanding why carpenter bees are attracted to your home is the first step to controlling the problem.
Are carpenter bees social or solitary?
Carpenter bees are generally solitary insects. They typically do not live and travel in colonies. During mating season, males may congregate and compete for females, but even then, the bees tend to keep their distance from each other.
These bees may be found nesting in close proximity in the same area, but their individual nests are not connected, and they will not interact or cooperate with each other. Carpenter bees may build nests next to those of others of their species but typically do not form social bonds.
They are typically more focused on eating, nesting, and mating than forming colonies like some other bee species.
How do you know if you have a carpenter bee infestation?
If you have a carpenter bee infestation, you may notice large, round holes in your wooden structures, such as your deck, fence, shed, or house. These holes may be about 1/2 inch wide and the sawdust left around the hole can offer a telltale sign of the presence of carpenter bees.
You may also see the bees themselves buzzing near the hole and hear a loud drilling sound if they are actively boring into the wood. Other signs include yellow stains and piles of sawdust beneath the hole.
In some cases, you may also see frass—a mixture of sawdust and bees’ excrement. Carpenter bees also tend to return to the same hole year after year, meaning you may notice multiple holes in the same area if the infestation has been going on for a while.
There may also be signs of nesting material in the area.
How do I find a carpenter bee nest?
Finding carpenter bee nests can be a tricky task because these bees can build nests in a variety of areas. However, there are few key signs that you can look out for that will help you identify where carpenter bee nests are located.
The first sign that you should look for is holes in wood surfaces. Carpenter bees will typically burrow into wood to create their nests, so if you see any holes in wooden surfaces like house frames, decks, and eaves you may have located a carpenter bee site.
To locate the nest you should look for sawdust-like material which is often found in entryways to and around carpenter bee tunnels.
In addition to looking for holes in wood, you should also keep an eye out for carpenter bees themselves. Carpenter bees are typically black with yellow hairs and are often confused with bumble bees. If you find one buzzing around a wooden structure you should investigate the area as they may have built a nest near the area.
Ultimately, the best way to find carpenter bee nests is to stay vigilant and investigate wooden surfaces and bee activity around the area. With a little bit of knowledge and some detective work, you can easily locate a carpenter bee nest.
What will run off carpenter bees?
Carpenter bees can be a nuisance, but there are several ways to deter them. The most effective means to discourage carpenter bees is to paint, varnish, or lacquer any wooden surfaces. This is particularly effective in outdoor areas that have wooden structures, as bees prefer unfinished wood.
If you have wooden structures, you can use lightweight plastic, hardware cloth, or aluminum screen over open areas to prevent access. You can also hang colored flags, reflective ribbons, balloons, or CDs near the nesting area.
Finally, if the nesting areas are known and accessible, you can apply insecticide dust or aerosols. However, applying insecticides should always be done wearing protective clothing and with great caution.
How can you tell a queen carpenter bee?
Queen carpenter bees are relatively easy to identify compared to worker bees. They are slightly larger than worker bees and are shiny black in color. Depending on the species, they may also have a bluish-green sheen.
Unlike worker carpenter bees, queen carpenter bees tend to remain in flight for longer periods of time and make fewer stops. In addition, they rarely land on flowers or vegetation while in flight. They are often seen patrolling near their nesting sites or hovering over vegetation around their nesting sites.
A queen carpenter bee will typically return to the same nesting site on a regular basis. When resting, they may be seen clinging to vegetation or the side of a structure near the nesting site. They have noticeably longer abdomens than worker bees and can be observed with their heads directed downwards.
Are all female carpenter bees queens?
No, not all female carpenter bees are queens. While every species of carpenter bee has a single queen bee, the majority of female bees in the colony are not queens. Rather, they are workers whose job it is to build the nest, search for food and take care of the eggs and larvae.
Carpenter bee workers are typically smaller than the queen bee and live shorter lives. Additionally, the queen bee is typically the only bee in the colony that is capable of laying eggs, while the worker bees are sterile.
Are there female bees that aren’t the Queen?
Yes, there are female bees that are not the Queen. Worker bees are female bees, usually the daughters of the Queen, that perform the majority of the tasks around the hive and are involved in almost all aspects of its functioning.
They are responsible for nectar and pollen collection, building and repairing wax comb, making honey, and feeding larvae. They also serve to protect and defend the hive and its inhabitants. In some specific species, female worker bees, called gamergates, can take over the role of the Queen if the existing Queen is removed or dies.
These gamergates can then lay eggs and continue colony growth.
What happens if you get stung by a female carpenter bee?
If you get stung by a female carpenter bee, you may experience some mild to moderate pain at the site of the sting. The majority of people do not experience an allergic reaction, although this is possible.
Most reactions to a carpenter bee sting are localized, meaning the effects are limited to the area of the sting. Symptoms may include redness, swelling, itching, and/or burning at and around the sting site.
Additionally, a small white mark may be visible where the bee first stung.
It is important to note that female carpenter bees can sting multiple times; if you are stung multiple times, it is best to seek medical attention. People who are allergic to bee stings should immediately seek medical attention following a carpenter bee sting.
Can male carpenter bees sting you?
Yes, male carpenter bees can sting. They have a powerful stinger like other bees do, but they rarely use it on people. Instead, male carpenter bees defend their territory by performing a loud buzzing behavior and dive-bombing intruders or predators, like birds and lizards.
However, they can sting and if they do, it’s painful. The sting of a male carpenter bee often causes reddening of the skin and localized soreness. As with any bee sting, some people may have a more severe reaction such as a localized infection from the sting, requiring medical attention.
If the bee does sting, it is best to seek medical attention.
How can you tell the difference between a female and a male carpenter bee?
The most reliable way to distinguish between a female and a male carpenter bee is by looking at their faces. Female carpenter bees have a black face, while males typically have a pale yellow face with a patch of white on their lower face.
Additionally, female carpenter bees tend to be much larger than the males, with a body length of ¾” to 1″, while males are usually only around ½” in length. Another difference between male and female carpenter bees is the antennae.
The antennae of the male carpenter bee is much longer and extends beyond the head of the bee, while the antennae of the female is shorter and appears to start at the eyes.
Which is bigger male or female carpenter bee?
Generally speaking, female carpenter bees are larger than their male counterparts. Female carpenter bees can measure up to 13 mm in length, while male carpenter bees measure up to 6 to 7 mm in length.
Female carpenter bees have larger eyes, more robust mandibles and can have either yellow or black bands on the abdomen. Male carpenter bees possess more yellow coloration, no yellow or black bands on the abdomen and have smaller eyes.
Although the size difference between male and female carpenter bees is noticeable, both genders of this species possess the same basic body shape.
Should I fill in holes from carpenter bees?
Yes, it is important to fill in holes from carpenter bees. This is because the holes in your wood provide an entryway for carpenter bees to make their nests, which can cause damage to your home. Filling the holes will ensure that the bees can not access the structures of your home.
In addition to filling in any existing holes, preventative measures should also be taken to deter carpenter bees from returning. This includes regularly cleaning out debris and sealing any cracks or crevices that may be providing an entry way for the bees.
