Carpenter Bees
Overview:

Carpenter bees get their common name from their habit of boring into wood to make galleries for rearing their young. Carpenter bees resemble bumblebees but their abdomen is largely bare and shiny.

Habits:

Carpenter bees are not social insects and do not live in nests or colonies. The adults over-winter, typically in abandoned nest tunnels. In the spring, they emerge and feed on nectar. To excavate galleries, female carpenter bees bore circular holes the same diameter as their bodies straight into wood, and then turn to tunnel along the grain of the wood.

Threats:

Carpenter bees are a serious property threat, and can cause structural damage over time if left untreated. They prefer weathered and unpainted wood. Male carpenter bees can be territorial and may hover in front of one’s face aggressively, but they have no stinger and these actions are merely for show. Female carpenter bees do have a potent sting, but it is rarely used.

Prevention:
  • Carpenter bees prefer bare wood, so painting and staining wood can sometimes deter them.
  • Routinely inspect wood on your property for signs of a carpenter bee infestation, including round, smooth holes.
  • In some cases, carpenter bees will attack stained or painted wood. If you suspect a carpenter bee infestation, contact a licensed pest professional.
