Carpenter Bee Control

Carpenter Bees get their common name from their habit of boring into wood to make galleries for the rearing of young. These stinging insects can be found worldwide, with seven sub-species occurring specifically in the United States. The eastern carpenter bee in particular is common in Ohio.

Carpenter bees are not social insects and do not live in nests or colonies. The adults overwinter, typically in abandoned nest galleries. In the spring, the survivors emerge and feed on nectar. Then mating begins and extends into nest-construction time.

Females of the eastern carpenter bee will nest in a wide range of woods, but prefer weathered and unpainted wood. Male carpenter bees tend to be territorial and often become aggressive when humans approach, sometimes hovering a short distance in front of one’s face or buzzing around one’s head. Since males have no stinger, these actions are merely show. However, the female does have a potent sting which is rarely used.

Carpenter bees rarely attack freshly painted or stained wood. They can be discouraged from boring into wood by applying a clear waterproofing product or varnish yearly, early in spring. Carpenter bees have difficulty clinging to smooth, glossy surfaces, which is why this is an effective preventative measure. Treated and abandoned entrance holes should be patched with wood filler and refinished to help prevent further use by carpenter bees.
