But what they do have are mandibles and they use their mandibles like teeth. Basically they use them to cut and tear through wood they target for nest making.

The entrance is a little less than a half-inch wide close to the same diameter as her body. In fact you can often find a substantial pile of sawdust beneath the hole where the carpenter is working. Note the shiny black abdomen characteristic of carpenter bees.

Within each chamber the female carpenter bee lays an egg on a ball of pollen and nectar she collected. The entrance to the nest can also have additional tunnels leading off of the main entrance. They prefer to live in wood where the female carves tunnels to host her eggs.

This initial tunnel creates one single entrance to the nest.
