Carpenter Bees Around the Home

Many reports of carpenter bees have been coming into the office so here’s a quick overview of carpenter bees:

  • you can trap them or use pesticides approved for carpenter bee removal (dusts or foaming sprays applied to the nest holes)
  • painting exposed wood is a longer-term solution to discouraging them from using your deck as a nesting site
  • carpenter bees are pollinators that don’t tend to sting
  • territorial males will hover around but disperse after females are done constructing egg chambers
  • females can winter over in the egg chambers and eggs will emerge next spring
