Carpenter bees get their common name from their habit of boring into wood. Carpenter bees do not eat wood but cause damage to structures by drilling circular holes to create tunnels inside wood. Unlike other common bees, such as honeybees and bumble bees that live in colonies, carpenter bees are not social insects and build individual nests into trees outdoors or into the frames, eaves or sides of buildings. Adult carpenter bees overwinter in abandoned nest tunnels where they have stored limited pollen to survive the colder temperatures. The bees that survive the winter will emerge in the spring to feed on nectar, mate and build galleries. They may reuse an already existing gallery or they may excavate new galleries. Female carpenter bees chew circular holes through wood to make individual galleries to lay eggs and protect their larvae as they develop. They are particularly inclined to build their galleries in soft, unpainted and worn wood, although some species may prefer hardwood. Wooden structures on the property, like decks and fences, are also prone to carpenter bee infestations. These work to save your wood structures without using pesticides that harm other useful insects. Honey bees will not go into the holes so you are not harming them.
