Carpenter Bees are a wood-destroying insect that can ruin wooden surfaces around your home such as decks, fences, posts and columns.  If you find a small pile of sawdust, you may have a carpenter bee!

How to Get Rid of Any Carpenter Bees

Carpenter bees ruin wood by boring tiny holes.

Carpenter bees can cause damage to wooden surfaces in and around your home. Although carpenter bees resemble bumblebees, carpenter bees do not sting as much. Male carpenter bees do not even have stingers. Female carpenter bees chew holes into wood and lay eggs inside. When the eggs hatch, the larvae also destroy more wood. Carpenter bees pose a threat to homes and other structures because they weaken the integrity of wooden structures and lower the value of the house.


  1. Vacuum small colonies of carpenter bees directly from the nest. New colonies have approximately 20 carpenter bees in addition to the queen. You might need to agitate or provoke the colony to encourage all of the bees to leave the nest.
  2. Spray an insecticide intended for bees around the nests to get rid of the male carpenter bees. Dust the holes with another insecticide that will coat carpenter bees leaving the holes. The insecticide dust is absorbed by the bees and and will kill them after they have left the nest.
  3. Block any existing holes with caulk, putty or wood filler to trap any carpenter bees inside. Carpenter bees do not try to tunnel out of holes so filling in the nests prevents the carpenter bees from reproducing. Spray the area with a bee-killer spray.
  4. Fill in any other cracks or damaged parts of the wood to prevent easy access for future carpenter bees. Apply a coat of varnish or paint to wooden surfaces to discourage carpenter bees from returning to their nesting site.
