What defines the frass of Bostrichid beetles?

The frass of Bostrichid beetles is characterized by being tightly packed and meal-like, with no distinct pellets. This particular structure is a result of the beetle's feeding habits and the way it digests the wood material. As Bostrichid beetles bore through wood, they consume the wooden material and excrete it in a form that resembles a fine powder or meal. This frass is often found around their entrance holes and can serve as an indicator of their presence.

In contrast, other types of frass from different wood-boring insects may have characteristics such as being granular, sandy, or fluffy, which are not typical of Bostrichid beetles. Recognizing the specific attributes of Bostrichid frass is essential for pest control professionals in accurately identifying infestations and determining the appropriate management strategies.
