  1. Locate the bees' nests

    Eastern carpenter bees live in unpainted or untreated wood, such as untreated decks, eaves and tree stumps. The nest entrances are small, circular holes that are about the size of a standard pencil eraser.

  2. Apply insecticide

    Apply an insecticide powder or spray to the bees' nests at dusk. Wear protective clothing, such as a long sleeved shirt and goggles, while applying the product. The eastern carpenter bee drills long, narrow tunnels in the wood that may reach 10 inches in length. It is often necessary to use an insecticide that features a powerful spray to reach the back of the bees' tunnel. Powder insecticide can be applied with a bulb applicator.

  3. Paint over treated carpenter bee nests

    After the eastern carpenter bees have been eliminated with insecticide, paint all exposed, untreated wooden surfaces with a latex paint. Apply a topcoat over the paint to seal the wood and prevent future carpenter bee infestations.
