What is a notable feature of carpenter bee bore holes?

The notable feature of carpenter bee bore holes is that they are larger than old house borer holes. Carpenter bees create relatively large, round holes, typically measuring about ½ inch in diameter, as they tunnel into wood to create nests for themselves. This distinguishes them from other wood-boring insects such as old house borers, which produce smaller and often more narrow holes.

Understanding the size and shape of these bore holes is critical in pest management because it helps pest control professionals identify the species causing the damage and determine the appropriate treatment methods. The larger size of carpenter bee holes allows technicians to differentiate them from those made by smaller wood-boring pests.

The other characteristics mentioned in the options, while they may have relevance in different contexts, do not accurately describe the distinguishing feature of carpenter bee holes. Their holes are not irregularly shaped, do not typically appear filled with powdery dust, and while the texture may vary, the defining characteristic remains the size of the bore holes.
