Carpenter bees are a large species that excavate wood, potentially damaging homes. California carpenter bees can range from 1.5 to 2 inches in length, and are most active in warmer climates.

“They build their nests in dead wood. So they make tunnels, and then they make little side tunnels that they then provision with a mixture of bone and nectar, and then lay their eggs in there.
