Wood Destroying Organism (WDO) Home Inspection Practice Exam

What is a common sign of an active beetle infestation within wooden structures?

1. Entry ovals

2. Galleries

3. Exit holes

4. Frass packs

The correct answer is: Exit holes

The presence of exit holes is a strong indicator of an active beetle infestation within wooden structures. These holes are small and typically round, often resembling a pinprick. They are formed when adult beetles emerge from the wood after completing their life cycle. The size and shape of these exit holes can vary depending on the species of beetle, but they serve as a clear sign that the wood has been infested and that beetles have matured and left the wood. Observing exit holes during an inspection highlights the need for further investigation into the extent of the infestation and potential damage caused to the wood. This evidence is critical for the identification of the species involved and helps determine the most appropriate pest management strategies to mitigate the problem and prevent further damage.
