Carpenter bees are large, black and yellow bees that can be mistaken for bumblebees. Unlike bumblebees, carpenter bees do not sting humans. However, they can cause significant damage to wood structures. Carpenter bees bore into wood to create their nests. They prefer untreated wood, such as porch railings, eaves, decks and fence posts. If left untreated, the holes created by carpenter bees can lead to the deterioration of the wood. In some cases, the structural integrity of the wood may be compromised.

What are carpenter bees?

Carpenter bees are beneficial insects that are attracted to sweet foods like sugar and honey. They can be found in the United States, Mexico, Central America, and South America. Their nests are typically made from wood or other materials such as mud, clay, or mud-packed dirt.

Carpenter bees are about 1/4 inch long. They have yellowish or black bodies with brown heads and antennae. Black bands or stripes run down the middle of their bodies and legs. Adult female carpenter bees make small holes in wood with their mandibles so they can lay eggs inside.

The carpenter bee is an aggressive pollinator that will sting if provoked or threatened. Carpenter bees do not sting unless they feel threatened by humans or pets. If you see a nest inside your house or apartment, leave it alone because the carpenter bee may be trying to protect her nest from being destroyed by humans or pets who are unfamiliar with its presence in your home environment.
