What is a defining feature of the exit holes made by Bostrichid beetles?

The defining feature of the exit holes made by Bostrichid beetles is that they are small and rectangular. Bostrichid beetles, commonly known as "wood borers," leave behind distinctive exit holes in the wood they invade. These holes are not large and rounded like those made by some other types of beetles; instead, they tend to be more narrow and elongated in shape, resembling a small rectangle. This characteristic shape is crucial for identifying infestations and diagnosing pest problems effectively in wooden structures. It helps pest control operators distinguish Bostrichid beetles from other wood-boring insects when assessing damage or planning treatment strategies. Understanding these characteristics is essential for anyone involved in structural pest control.
