What are Carpenter Bees?

Carpenter bees are a category of bee that is common in North America. Their name is derived from the fact that they often build their nests in wood. Sometimes they are also referred to as wood bees.

Do Carpenter Bees Sting?

They are distinguishable by their black and yellow coloring, and they can be quite large compared to other types of bees. Carpenter bees do not prefer to sting humans unless they are provoked, but they can sting other animals.

Unlike termites, carpenter bees do not feast on wood. They drill circular holes in wooden structures to lay their eggs. While the damage they cause is often cosmetic, it can also weaken the structure of a building over time.

Unlike social bees, carpenter bees are solitary insects that build their nests one at a time. They use their strong mandibles to carve tunnels in wood – usually in porch columns, eaves, or window frames.

Carpenter bees are identical to bumble bees in appearance, but their abdomens lack yellow markings. Carpenter bee abdomens are smooth and shiny, unlike bumble bee abdomens which are hairy and yellow.

Carpenter bees have a variety of shapes and sizes, as there are seven different species in the United States and hundreds globally.

Eastern carpenter bees, for example, closely resemble bumblebees in appearance, with sleek black bodies and a patch of yellow hair on the thorax.

California and female valley carpenter bees, for example, have more metallic, multicolored bodies.

Where Do Carpenter Bees Live?

Carpenter bees are a bee species that can be found all over the world. They receive their name from the fact that they prefer to make their nests out of wood. Carpenter bees tunnel through the wood and produce holes in it, weakening it.

These bees are attracted to softwood, such as wood around homes. They will bore into the softer woods and lay their eggs. The eggs will hatch, and the larva will eat the wood until they pupate.

The process of female carpenter bees boring into wood to lay eggs can lead to warping of the structure if it is not treated.

What Do Carpenter Bees eat?

Carpenter bees feed on nectar from flowers. This makes them important pollinators for many plants.

Many people are always of the opinion that carpenter bees eat wood. However, that is not true. They rather lay eggs and reproduce in the woods.

They drill into the wood to create tunnels in which their eggs will be laid. The larvae that hatch from the eggs will then eat the wood they will grow, eventually becoming adults who will then repeat the process.

Only the baby wasps feed in tiny amounts in the woods; the adult wasps do not do so.

When Are Carpenter Bees Active?

Carpenter bees are active during the spring and summer months when the weather is warm. They are attracted to wood and can often be found nesting in trees, decks, and other wooden structures.

In general, Carpenter bees are more active during the morning and afternoon hours. They are not generally aggressive and will only sting humans if they feel threatened.

What are the Signs of a Carpenter Bee Infestation?

The smooth, round holes that carpenter bees bore into the wood are the most common signs of a carpenter bee infestation.

Homeowners should inspect the perimeter of their home and surrounding property for the presence of these holes and hovering bees on a regular basis to detect early damage to buildings.

Carpenter bees prefer bare wood, so using paint and painting and staining it can help deter them. They will, however, attack stained or painted wood on occasion.

To avoid carpenter bees and keep them out of the house, use a silicone-based caulk to seal cracks and crevices along the foundation and walls, repair any tears in screens, and keep doors closed at all times.

Do Carpenter Bees Sting?

The males of the carpenter bees do not sting, but they are territorial and frequently come into contact with humans.

Males will hover close to people, especially if there is a sudden movement, but this will only cause unnecessary fear. Female carpenter bees sting on very rare occasions and only when provoked.

Are Carpenter Bees Aggressive?

Carpenter bees are not generally aggressive, but the male can be quite territorial if their nests are threatened. They will often fly around and even dive-bomb people or animals who get too close to their nests.

Even so, carpenter bees are not typically aggressive. The size and loud buzz of their attack can be intimidating, but they will usually only sting humans if they feel threatened.

How to Get Rid of Carpenter Bees?

Carpenter bees can be a nuisance, and homeowners often want to know how to get rid of carpenter bees.

When it comes to eliminating carpenter bees, you have two primary options: chemical or non-chemical.

To apply the chemical option, you will need a product that is designed to be sprayed into the galleries the bees use and left open for the females to enter; this will kill them. The non-chemical approach is more labor-intensive, but it can be just as effective if done properly.

Carpenter bees can also be controlled with the use of an appropriately labeled insecticide. It is important to read the label carefully and follow all instructions when using any type of pesticide.

Once the Carpenter Bees have been exterminated, a few steps still need to be taken to ensure that they do not come back.

First and foremost, the holes that the Carpenter Bees created need to be sealed off so that they cannot overwinter in those spaces. Additionally, any food sources that may have attracted the Carpenter Bees in the first place (such as rotting wood or pollen) should be removed.

How to Prevent Carpenter Bees?

Carpenter bees can be a nuisance because they consume the wood, making it weak and susceptible to damage. There are certain things you undertake to prevent them from nesting in your wood:

  • These bees are attracted to unsealed openings on homes and buildings. If you seal these openings, you can deter carpenter bees from nesting on your property. This will help keep you and your family safe from their stings.
  • One of the best ways to prevent carpenter bees from infesting your home is to treat the wood with a sealant. This will make it more difficult for them to penetrate and lay their eggs. You can also use other techniques such as traps, exclusion barriers, or pesticides.


Female carpenter bees can sting, but they do so infrequently. Unless provoked or threatened, no. Male bees cannot sting; they exist to protect the nest and to add beauty and charm to our gardens.
