Often mistaken for bumblebees, Carpenter bees have smooth, shiny black abdomens (unlike the fuzzy abdomens of bumblebees). They are solitary bees, meaning they do not live in colonies.
Simply spraying the bees as they fly by will not solve the issue, as the eggs are laid deep inside the wood tunnels. We apply a specialized insecticidal dust directly into the galleries. Once the bees are eliminated, the holes must be sealed to prevent future generations from reusing the tunnels.
