The exit holes for Bostrichid beetles are classified as "big," which ranges from 1/8" to 3/8". This classification is significant for pest control operators as it helps in identifying the type of infestation present based on the size of the exit holes observed in wood or structural materials.

Understanding the size of these exit holes aids in determining the appropriate control methods and potential damage assessment necessary for managing Bostrichid beetle infestations effectively.
