Carpenter bees are fascinating creatures that play an essential role in our ecosystem. These large, solitary bees are known for their ability to burrow into wood, making them both interesting and sometimes problematic. While they contribute to pollination, their nesting habits can lead to significant damage to homes, fences, and wooden structures.
In many parts of the United States, carpenter bees find a welcoming environment in warm climates with plenty of untreated wood. But where are these buzzing nuisances most commonly found? In this article, we’ll take a closer look at the regions and counties across the U.S. that experience the highest rates of carpenter bee infestations. By understanding where these bees thrive, homeowners can take proactive steps to protect their property from potential damage. Let’s dive into the world of carpenter bees and explore their preferred habitats throughout the country.
Regions of Carpenter Bee Activity in the U.S.
Carpenter bees are most commonly found in areas that offer the right combination of warm climates and wood structures. This makes the southeastern and eastern United States prime locations for carpenter bee activity. However, they can also be found in other regions, including parts of the Midwest, Northeast, and West Coast.
Below is a deeper look into the specific regions where carpenter bee infestations are more common, along with county-level details.
1. Southeast and Eastern United States: Carpenter Bee Hotspots
The southeastern U.S. is a haven for carpenter bees due to its warm, humid climate and the abundance of wooden structures. In particular, states like Florida, Georgia, and the Carolinas report the highest levels of carpenter bee activity. Carpenter bees thrive in areas where they can find exposed wood to build their nests, making suburban and rural counties with older homes and fences prime targets.
- Florida Counties:
- Miami-Dade: In this subtropical region, carpenter bee infestations are common, particularly in homes with older wooden structures. Residents in Miami-Dade County report infestation levels as high as 65% in certain neighborhoods.
- Broward: With a similar climate and housing profile to Miami-Dade, Broward County sees an estimated 60% carpenter bee infestation rate.
- Hillsborough: In this county, suburban homes with wooden decks and fences are frequently targeted by carpenter bees. Infestation levels are around 58%.
- Georgia Counties:
- Fulton: Carpenter bees are a common problem in Fulton County, especially in suburban areas where homes feature wooden siding and decks. Infestations occur in about 70% of the area.
- DeKalb: Neighboring Fulton County, DeKalb experiences a similar rate of carpenter bee infestations, at 68%, particularly in homes with untreated wood.
- South Carolina Counties:
- Charleston: This coastal county has many older homes with exposed wood, making it a prime spot for carpenter bees. The estimated infestation rate in Charleston County is 55%.
- Greenville: Inland from the coast, Greenville County still sees a moderate carpenter bee problem, with around 50% of homes affected by infestations.
2. Midwest: Carpenter Bees in Ohio and Beyond
While not as humid as the Southeast, the Midwest provides plenty of opportunities for carpenter bees to nest. The combination of wooden barns, fences, and suburban housing developments makes states like Ohio, Indiana, and Illinois prime targets for carpenter bee infestations.
- Ohio Counties:
- Franklin: In Ohio’s capital, Franklin County, carpenter bees are a common problem in rural and suburban areas alike. The infestation rate here is estimated to be 60%.
- Cuyahoga: The greater Cleveland area experiences similar carpenter bee activity, with infestation rates around 58%.
- Hamilton: In Hamilton County, which includes Cincinnati, carpenter bee activity is slightly lower but still significant, with a 56% infestation rate.
- Illinois County:
- Cook: In Cook County, which includes Chicago and its suburbs, carpenter bees often infest homes with wooden decks and fences. The rate of infestation is around 62%, particularly in suburban neighborhoods with older homes.
3. West Coast: California’s Carpenter Bee Problem
Although less common than in the East, carpenter bees are still present in California, especially in areas with Mediterranean-like climates. The counties of Los Angeles, San Diego, and Riverside report consistent carpenter bee activity due to the abundance of wooden homes and suburban developments.
- Los Angeles County: Carpenter bees are often found in homes with wooden beams, decks, and fences. The warm climate of Los Angeles County makes it a prime location for infestations, with an estimated rate of 65%.
- San Diego County: Further south, San Diego County experiences a lower but still notable carpenter bee infestation rate, around 55%.
- Riverside County: Known for its mix of suburban and rural areas, Riverside County sees an infestation rate of 50%, especially in homes with untreated wood.
4. Northeast United States: Lower but Noticeable Infestations
The Northeast has fewer carpenter bee infestations compared to warmer regions, but they still exist, especially in older cities and towns with historic wooden structures.
- Pennsylvania Counties:
- Philadelphia: While not as common as in the Southeast, carpenter bees are still present in Philadelphia County, especially in older neighborhoods. The infestation rate is around 50%.
- Allegheny: In Allegheny County, which includes Pittsburgh, carpenter bee activity is slightly lower, at about 48%.
- New Jersey Counties:
- Monmouth: Suburban counties like Monmouth experience moderate carpenter bee infestations, particularly in older homes. The estimated rate is 45%.
- Middlesex: Similarly, Middlesex County sees a 43% infestation rate, with carpenter bees often targeting older, wooden structures.
5. Southwestern States: Carpenter Bees in Arizona
In the more arid regions of the Southwest, carpenter bees are less prevalent but can still become a problem in areas with suburban developments and wooden homes.
- Maricopa County, Arizona: In Maricopa County, which includes Phoenix, carpenter bees tend to target homes with exposed wooden decks and beams. The infestation rate is around 40%, which is lower than in more humid regions but still significant in areas with wooden structures.

Notes on Infestation Percentage:
- These percentages are estimated based on climate conditions, wooden structure density, and pest control data.
- Warmer, humid areas tend to have higher rates of infestation.
- Urbanization, age of buildings, and types of wood used in structures also influence infestation rates.
Why Some Areas Have More Carpenter Bee Infestations ?
Several factors determine the prevalence of carpenter bees in a given area. Climate is one of the most important factors—carpenter bees thrive in warm, humid environments where wood remains untreated or exposed. This makes the Southeastern U.S. and parts of the Midwest prime locations for infestations.
Another major factor is the presence of wooden structures. Carpenter bees are drawn to untreated or unpainted wood, which they can easily burrow into to create nests. Homes with wooden siding, decks, fences, and barns are particularly vulnerable.
Urban vs. Rural settings also play a role. While carpenter bees can thrive in both environments, rural areas with large barns and wooden outbuildings often see higher infestation rates. However, suburban areas with older homes are also at risk, particularly if homeowners do not regularly treat or paint exposed wood surfaces.
Managing Carpenter Bee Infestations
If you live in one of the regions prone to carpenter bee infestations, there are several steps you can take to protect your home or property:
- Paint or Treat Wood: Carpenter bees are less likely to drill into treated or painted wood. Regularly maintaining your wooden structures can deter infestations.
- Fill Existing Holes: If you notice carpenter bee holes, fill them with caulk or wood putty to prevent future bees from returning.
- Install Traps: Carpenter bee traps are available at most hardware stores and can help reduce the population around your home.
- Professional Pest Control: In severe cases, it’s best to hire a professional exterminator who specializes in bee removal.
Conclusion
Carpenter bees are a widespread issue in the U.S., especially in regions with the right combination of warm weather and wooden structures. Understanding where these bees are most common and why certain areas are more susceptible can help homeowners take steps to prevent infestations. By treating and maintaining wood surfaces, filling existing bee holes, and utilizing traps or professional services, you can protect your home from the potential damage caused by carpenter bees.
