Carpenter bees are fascinating yet often misunderstood insects. Unlike their relatives, honeybees and bumblebees, carpenter bees don’t live in hives. Instead, they carve out nests in wood, which can sometimes cause structural damage. Knowing how to find a carpenter’s bee nest is essential for effective pest control and prevention.
Carpenter bees prefer soft, untreated wood for nesting. Common nesting sites include eaves, decks, fences, and wooden furniture. They are particularly attracted to cedar, redwood, cypress, and pine. Look for them around wooden structures in your yard, especially during spring when they are most active.
Understanding Carpenter Bees
Carpenter bees are large, solitary bees often seen buzzing around wooden structures. They get their name from their nesting behavior, as they bore into wood to create their homes. While they may look intimidating, carpenter bees are generally non-aggressive and rarely sting.

Comparison Between Carpenter Bees and Other Bees
| Feature | Carpenter Bees | Honeybees | Bumblebees |
| Size | Large, similar to bumblebees | Smaller than carpenter bees | Similar to carpenter bees, often larger |
| Nesting Structure | Solitary nests, although multiple bees may nest near each other | Highly social, living in large colonies with a complex hierarchy | Social bees, but colonies are smaller than honeybees |
| Distinguishing Feature | Lack of hair on the abdomen | Fuzzy appearance due to hair on their bodies | Hairy abdomen, making them look fuzzy |
| Nesting Location | Bore into wood to create nests | Build hives in tree cavities, man-made hives, or other sheltered areas. | Nest in the ground, often in abandoned rodent burrows or under piles of debris |
Signs of Carpenter Bee Nests
Finding a carpenter bee nest involves looking for specific signs. Carpenter bees create perfectly round entry holes about half an inch in diameter. These holes are usually found in exposed wooden surfaces. Around these holes, you may notice sawdust or frass, which is a clear indication of their presence. Additionally, you might see the bees themselves entering and exiting these holes. Carpenter bees typically construct their nests by tunneling into wood. The tunnel, called a gallery, can extend several inches into the wood. Over time, they may branch off into multiple galleries, creating an extensive network. Understanding the type and extent of the nest can help in determining the best method for removal and prevention. To locate a carpenter bee nest, start by observing the bees. They are most active during the daytime in warm weather. Watch for their flight patterns and note where they land. Inspect wooden structures closely for the round entry holes mentioned earlier. Using a flashlight, you can also look inside these holes to confirm the presence of bees or their larvae.
Carpenter Bee Foods and Habitat Preferences
Carpenter bees primarily feed on nectar and pollen, much like other bees. However, their nesting preferences make them unique. They thrive in environments where suitable nesting sites are abundant. Ensuring your wooden structures are treated or painted can make them less attractive to these bees. If you find a carpenter bee nest, there are several steps you can take. First, consider treating the wood with insecticide dust specifically designed for carpenter bees. This can be applied directly to the nest entrance. Seal the entry holes with wood putty or caulk after ensuring the bees are no longer active. Prevent future infestations by painting or treating exposed wood surfaces. Myths and Facts About Carpenter Bee Nesting Carpenter bees, known for their habit of boring into wood to create nests, are often surrounded by myths and misconceptions. Here are some common myths and the corresponding facts about carpenter bee nesting.| Myth | Facts |
| Carpenter bees eat wood. | Carpenter bees do not eat wood; they excavate it to create nests for their offspring. |
| Carpenter bees prefer painted wood. | Carpenter bees are more likely to nest in untreated, weathered, or unpainted wood. |
| All carpenter bee nests are large and easy to spot. | Carpenter bee nests often consist of small entrance holes and can be hidden, requiring careful inspection to find. |
| Sealing the entrance holes will get rid of carpenter bees. | Sealing holes without treating them first can trap bees inside, leading to further damage as they try to escape. |
| Carpenter bee damage is always superficial. | Over time, carpenter bee tunnels can cause significant structural damage if left untreated. |
