How large is the emergence hole created by old house borers?

The emergence hole created by old house borers is typically around 1/4 inch in diameter. This size is significant because it helps in identifying the presence of these pests during an inspection. The 1/4 inch hole is a distinct indicator of infestation and is characteristic of the species, making it easier for pest control professionals to diagnose and take appropriate action. Recognizing the size of the emergence hole can assist in understanding the life cycle of the old house borer and the potential structural damage they may cause, as they can bore into wooden structures. Understanding these characteristics is essential for effective pest management and control strategies.
