Carpenter bees do not live in nests or colonies. During the winter, the adults stay in abandoned nest tunnels. In the spring, they emerge to feed on nectar. The female carpenter bees bore circular holes into wood and then tunnel along the grain of the wood.
Over time carpenter bees can cause a serious property threat if left untreated. They prefer unpainted and weathered wood. The male carpenter bee can be territorial and may hover in front of one’s face, but they have no stinger and do this mainly for show. The female carpenter bee does have a potent sting, but it is rarely used.
Painting and staining wood can deter carpenter bees as they prefer bare wood. Routinely inspect wood on your property for round smooth holes.
