The Difference Between Carpenter Bees and Carpenter Ants

The Difference Between Carpenter Bees and Carpenter Ants

When it comes to pests that can cause damage to your home, carpenter bees and carpenter ants are two common culprits. While they may sound similar, these insects have distinct differences in their behavior, appearance, and the damage they can cause. Understanding these differences can help you identify and address any infestations more effectively.

Carpenter Bees

Carpenter bees are large, solitary bees that are often mistaken for bumblebees due to their similar appearance. However, there are a few key differences that can help you distinguish between the two. Carpenter bees have a shiny, black abdomen, while bumblebees have a fuzzy abdomen with yellow markings. Additionally, carpenter bees have a distinct habit of drilling perfectly round holes into wood, which is where they lay their eggs.

Unlike other bees, carpenter bees do not live in colonies. Instead, they are solitary insects that prefer to nest in untreated, unpainted wood. Common nesting sites include eaves, decks, and wooden furniture. While the drilling of these holes can cause cosmetic damage to your property, the real concern with carpenter bees lies in the potential structural damage they can cause over time.

Female carpenter bees are equipped with a stinger, but they are generally non-aggressive and rarely sting unless provoked. However, male carpenter bees can be territorial and may exhibit aggressive behavior, often hovering near their nests and buzzing loudly.

Carpenter Ants

Carpenter ants, on the other hand, are social insects that live in colonies. They are typically larger than carpenter bees, ranging in size from ¼ to ½ inch. Carpenter ants have a black or dark brown color and can be identified by their segmented bodies and elbowed antennae.

Unlike carpenter bees, carpenter ants do not drill holes in wood. Instead, they excavate galleries within the wood, creating smooth tunnels and chambers. These galleries serve as their nests and can extend deep into the wooden structures of your home. Over time, this can weaken the wood and potentially cause structural damage.

While carpenter ants do not feed on wood like termites do, they are attracted to moist or decaying wood. This means that if you have any water damage or wood rot in your home, you may be more susceptible to a carpenter ant infestation.

Prevention and Treatment

Preventing and treating carpenter bee and carpenter ant infestations require different approaches.

To prevent carpenter bee infestations, it is important to seal any cracks or openings in your home’s exterior, especially in wooden structures. Painting or staining exposed wood surfaces can also help deter these bees from nesting. If you already have carpenter bees nesting on your property, it is best to consult with a professional pest control service to safely remove them and protect your home from further damage.

Carpenter ant prevention involves addressing any moisture issues in your home, such as fixing leaks and improving ventilation. Removing any decaying wood or debris around your property can also help reduce the risk of infestation. If you suspect a carpenter ant infestation, it is recommended to contact a professional pest control service for an inspection and appropriate treatment.


While both carpenter bees and carpenter ants can cause damage to your home, they have distinct differences in their behavior, appearance, and nesting habits. Understanding these differences can help you identify the type of infestation you are dealing with and take appropriate measures to address it. Whether you are dealing with carpenter bees or carpenter ants, consulting with a professional pest control service can ensure effective and safe removal of these pests from your property.
