Why Carpenter Bees Are Considered Pests

Carpenter bees are often considered pests due to their nesting habits and potential damage to wooden structures. While they have their ecological significance, their activities can pose challenges and concerns for homeowners and property owners. Here are some reasons why carpenter bees are sometimes labeled as pests:

  1. Wood Damage: Carpenter bees excavate tunnels by boring into untreated or weathered wood, including structures such as decks, eaves, fascia boards, and wooden furniture. Over time, their repeated nesting activities can weaken the wood, leading to structural damage and compromising the integrity of the affected objects or buildings.

  2. Aesthetic Concerns: The entry holes created by carpenter bees can be unsightly, especially when they occur on visible wooden surfaces. These perfectly round holes, along with sawdust or "frass" deposited beneath the entrance, can detract from the appearance of homes and other wooden structures.

  3. Nesting Site Conflicts: Carpenter bees often choose nesting sites in high-traffic areas, such as near entrances, windows, or outdoor living spaces. This can create conflicts between the bees and humans, as people may feel uncomfortable or threatened by their presence, especially if they display aggressive behaviors.

  4. Secondary Infestations: Once a carpenter bee creates a tunnel, other wood-boring insects, such as wood-boring beetles or carpenter ants, may be attracted to the weakened wood, exacerbating the damage and potential problems.

  5. Lack of Control Methods: Unlike honeybees or bumblebees, carpenter bees do not have a central colony or a queen to target for control measures. This makes managing and preventing carpenter bee infestations more challenging, as each female carpenter bee creates her own nest and defends it individually.

  6. General Nuisance: They are large and noisy bees, and their presence can be unsettling to some people.

While carpenter bees are important pollinators and have their ecological role, it's important to find a balance between appreciating their ecological significance and addressing the concerns they may pose to human structures and properties.


Here are some tips to prevent carpenter bees from nesting in your home or other wooden structures:

  • Seal up any holes or cracks in your home or other wooden structures that are larger than 1/4 inch in diameter.

  • Paint or stain your wood surfaces to make them less attractive to carpenter bees.

  • Plant bee-friendly flowers in your garden to attract other bees, which will help to deter carpenter bees.

  • Remove any dead or dying trees or branches from your property.

  • Do not disturb a carpenter bee nest. The bees will eventually leave on their own.
