About Carpenter Bees

Carpenter bees have a bit larger and rounder head than bumble bees and a thick band of orange-brown hairs covering their thorax. Carpenter bees build nests in wood structures, preferring softwoods. They create nests by burrowing into wooden doors, windowsills, wooden lawn furniture, decks, roof eaves, shingles, railings, and more. They build nests in human crafted wood as well as in trees. Adult males and females emerge in the spring to reproduce after spending the winter in their wood tunnels.  Females deposit an egg and seal off each chamber. Carpenter bees tend to deposit 6 to 8 eggs at a time. 

Carpenter Bees life cycle includes:

  • Spending an average of 2 days as an egg
  • 15 days as a larva, 
  • 4 days in a prepupal stage
  • 15 days as a pupa. 

Development from egg to adult may take about 3 months. Adults come out in August, feed, and then go to the same tunnel for the winter. The bees may live as long as three years. They range in size from about 19 to 25 mm long. Males have a yellow patch on their faces, and the female faces appear solid black.
