Their carpenter related name comes from their habit of excavating holes in wood—they rear their youngsters there. 

The adults of carpenter bees overwinter individually in brood tunnels they constructed previously. 

Those that happily survive the winter emerge and mate the following spring.

Later in the summer, the new generation of adult bees emerges in the environment and forages of flowers. 

They’ll return to wood in the fall for hibernation.

3. Then, seal the hole with steel wool. WD 40 spray comes with its own straw—you can stick it into the nest.

4. Repeat this method for 2 to 3 days. Do it until you notice no movement inside the wood.

5. In the end, cover the hole with caulk and coat it with some paint or varnish to keep future bees out.

Important: Read safety precautions before you use WD40.
