Approximately what size hole do carpenter bees typically make?

Carpenter bees are known for their distinct galleries that they create by boring into wood. The size of the holes they make is approximately 1/2 inch in diameter. This size is significant because it allows them to access the softer, less dense wood within, as they prefer to nest in untreated or weathered wood that is easier to excavate. Understanding the size of the holes is crucial for identification purposes, as it helps differentiate them from other wood-boring insects whose holes may be larger or smaller. Recognizing these characteristics aids in effective inspection and management strategies for infestations.
