Given the time, money and effort that homeowners invest into caring for their wooden decks, it only makes sense to protect them from carpenter bees that are capable of causing major damage to their property. Whether you are looking for tips to get rid of carpenter bees or want to prevent an infestation before it even begins, knowing what carpenter bees look, how to spot them, and how to deal with them can save you thousands of dollars in wood repair services and months of trouble.
Characteristics of Carpenter Bees
Scientifically known as Genera Xylocopa and Ceratina, carpenter bees get their name from their habit of boring into wood like a carpenter and can be categorized into two categories – large and small. Large carpenter bees (Xylocopa) look similar to bumble bees, have yellow hair and yellow sections on the face but often lack yellow stripes or hair on their abdomen, and their size varies from anywhere between 12 to 25 mm. Small carpenter bees (Ceratina) are less than 8 mm long, have a metallic appearance and scanty hair on the body. Carpenter bees are typically attracted by weathered or unfinished wood and while they do not feed on wood, they dig up tunnels in the eaves of your home, decks, siding, porches, cladding and headboards and use them as nests. If left untreated, a carpenter bee infestation can continue to spread and invite expensive wood rot repairs.
Signs of Infestation
A carpenter bee infestation can be easily spotted if you look for the following signs:
- Round, smooth entry holes in wooden decks
- The presence of sawdust wherever holes have been drilled
- A yellowish combination of bee droppings and pollen near the holes
- Annoying flight activity of male carpenter bees
- Wood damage caused by excavation
- “Frass” that looks like sawdust near drilled areas
Unlike bumble bees, carpenter bees are solitary creatures that hibernate over the winter months. They are commonly found in abandoned nest tunnels and surface during the spring to feed on nectar.
Diet and Habitat
Carpenter bees don’t feed on wood but they live on nectar and pollen and they do not live in nests or colonies. Female bees bore holes in soft wood to lay eggs and protect their developing larvae. The holes that they drill can be about 1/2 inch in diameter. Carpenter bees prefer to nest in unfinished wood as it is easier to drill and enables them to create tunnels. Seasoned hardwoods, softwoods and decaying woods are relatively vulnerable to pest infestations.
Other Threats Posed by Carpenter Bees
Carpenter bees pose a serious threat to property as they can damage the structure over time if the infestation is left untreated. Male carpenter bees are generally protective about their territory and while they do not sting, they may aggressively hover around residents which can be very annoying. Female carpenter bees may sting, however it is not potent and they rarely use it.
Carpenter Bee Prevention – Tips to Protect Wood from Damage
- Carpenter bees prefer bare wood, so painting and staining wood can sometimes help deter them.
- If your house is infested with carpenter bees, spray a residual insecticide in the affected areas.
- Plug all the holes during the fall using cork or putty.
- If you don’t want to use chemicals, hang traps at all the entry points including the peaks and corners of your home.
- Seal and caulk all the cracks, crevices and exterior openings to prevent nesting activity.
Even with all these precautionary measures, carpenter bees will sometimes still attack stained or painted wood, so it is best to contact a pest control professional for proper carpenter bee control.
