Can Carpenter Bees hurt you?
Carpenter bees; Carpenter bees can burrow in untreated wood around the outside of the house causing damage. The female can sting if handled or poking at the nesting area. Adult females emerge from their tunnels in August returning to the tunnels for the winter. Carpenter bees are creatures that are mostly harmless to humans, but can be very damaging to wooden structures. Carpenter bees are named so because they drill into wood to lay their eggs and build their nests. They're also pollinators, which make them very important for helping crops and gardens grow.
Understanding Carpenter Bees
Carpenter bees nest in softwood and pithy stems of plants. Nests usually consist of tunnels half of an inch in diameter and 6-to-10 inches deep and may include several brood chambers. Carpenter bees may buzz like saws when constructing nests (hence their name), but they do not eat the wood. Instead, they forage on flowering plants, feeding on nectar, with the females collecting pollen for their offspring. When they have a sufficient plug of pollen in a chamber, females lay an egg on it, and then seal the chamber with wood chips. Another plug of pollen is then added for numerous chambers per tunnel. Development from egg to larva to adult may take about three months. Carpenter bees grow over winter to adults, often in old tunnels. There is only one generation a year.
How can I get rid of Carpenter bees?
For Saftey reasons you may want to call a professional that can safely remove the Bees.
Luckily, there are a number of ways to get rid of carpenter bees, some without using insecticide, and prevent them from causing any more damage to your property. Carpenter bees prefer weathered softwood. Place untreated, unpainted softwood boards in areas where you have problems. They will drill their holes into these boards instead and lay their eggs in these "nests.' After they have become inactive in your area (around Nov or Dec), take the boards into a forested area and leave them there. When they emerge around mid-March, they will be far from you. They tend to come back to where they were born to create their own nests and lay their eggs. Therefore, they will return to the woods and not to your deck or porch. You have exported your problem without introducing toxic chemicals into your own neighborhood. Hang small shallow buckets filled with water and a squirt of dish soap near carpenter bee holes. They fly in to get some water, but their wings get covered with soap, and they cannot fly out.
