Why Carpenter Bees Need to Be on Your Radar

Carpenter Bees

Carpenter bees are wood-boring insects but don't eat the wood like termites do. Instead, they excavate galleries in wood to deposit their larvae and can drill tunnels extending 10 feet long into a structure! Not only that, but their galleries can also:

  • Cause Wood Rot - Their unsightly galleries allow water seepage deep into the wood, weakening the wood and facilitating wood rot.
  • Invite Termites - Your buildings are more prone to termites since they are attracted to soft, damaged wood,
  • Attract Woodpeckers - If you have carpenter bees, noisy woodpeckers often join the party. These birds will relentlessly peck into the wood to reach the bee larvae and cause more property damage! 

What's worse is these pests often return year after year to the same location, expanding on their previous year’s work and drilling new ones! Fortunately, carpenter bee damage is relatively easy to spot. Here's what you need to be on the lookout for: 

  1. Perfectly round holes about a half-inch in diameter
  2. Piles of sawdust (“frass”) near where they are digging
  3. Yellow excrement stains on the wood below their holes
