What is the typical size range of a carpenter ant?

The typical size range of a carpenter ant is 6-12 mm, which aligns with their characteristics as one of the larger common ant species. Carpenter ants are known for their robust bodies and can vary in size, but individuals typically fall within this measurement range. This size accommodates their role within their ecological niche, as they need to be sufficiently sized for their behavior in excavating wood and establishing their large colonies, which can often be found in decaying or moist wood. Understanding this size range is important for identification and for recognizing the potential for issues they can cause in homes and structures.
