How do you fill carpenter bee holes?
If the bees are already at work on your home: Fill Abandoned Holes: When carpenter bees emerge in spring and again in fall, fill holes with a bit of steel wool, a wad of aluminum foil, a dowel and wood glue, or even caulk. After filling the holes completely, paint over them.
Carpenter bees overwinter as adults, often in old tunnels. There is only one generation a year. Like other native bees, carpenter bees are important pollinators in native plant communities, gardens, and in some crops. As they visit flowers and feed on nectar, they pick up and transfer pollen.
- The male bee is unable to sting. It is the male carpenter bee, which is most often noticed. They hover in the vicinity of the nest and will dart after any other flying insect that ventures into their territory. A common behavior of the males is to approach people if they move quickly or wave a hand in the air.
- Male bees often are seen hovering near nests, and will approach nearby animals. However, males are harmless, since they do not have a stinger. Female carpenter bees are capable of stinging, but they are docile and rarely sting unless caught in the hand or otherwise directly provoked.

However, if the infestation is extensive or has been going on for years, the sheer number of tunnels can cause problems, including: Stains: Feces of carpenter bees can stain wood.
