What type of emergence hole is produced by old house borers?

The emergence hole produced by old house borers is characterized as an oval, approximately 1/4 inch in size. This specific measurement and shape are significant for identification purposes, helping pest control professionals determine the presence of old house borers in wood structures. These borers are the larvae of wood-boring beetles that create these distinct holes as they exit the wood after developing inside it.

Identifying the emergence holes correctly is essential because it informs pest management decisions, including whether further inspection or treatment is needed. The unique oval shape and size set these holes apart from others caused by different species, which may have round or differently sized holes. Understanding these characteristics enables pest control specialists to provide accurate consultations and effective solutions for wood damage issues.
