Carpenter bees construct their nests in wood and are known for their ability to burrow into wood. Although you may see some sawdust outside the holes of their nests, carpenter bees do not eat the wood. Like most other bees, they feed on nectar and pollen from plants. Carpenter bees can form perfectly circular holes measuring about 16mm in wood. They do not eat the wood, but rather vibrate their bodies as they grind their mandibles against the wood – a sound that humans can actually hear.
Carpenter bees are very similar to bumble bees in both size and appearance but can be distinguished by their shiny black abdomen. Carpenter bees are also solitary insects that do not form large colonies. Instead, they make individual nests in trees or parts of buildings like the sidings or frames.
