What is the shape of the exit hole created by Lyctid beetles?

The exit holes created by Lyctid beetles are characterized by their round shape. This is important to note because identifying the exit hole can aid in confirming the presence of these pests and differentiating them from other wood-boring insects. The round holes are typically about 1/16 to 1/8 inch in diameter and are a result of the adult beetles emerging from the wood after completing their larval development inside it.

Understanding the physical characteristics of these holes is crucial for pest control professionals, as it assists in determining the appropriate treatment methods and confirming the type of infestation. In contrast, other shapes such as oval, square, or rectangular do not correspond to the exit holes made by Lyctid beetles and could lead one to misidentify the type of pest present. Therefore, recognizing the rounded exit holes is essential for effective pest management.
