Wood Destroying Organism (WDO) Home Inspection Practice Exam

Identifying a pest problem related to wood-destroying organisms is significantly aided by observing the presence of fecal pellets. Fecal pellets are indicative of certain wood-destroying insects, such as termites and wood-boring beetles, and their presence can confirm ongoing infestations. These droppings are typically found near damaged wood and can provide insights into the type of pest present.

The analysis of fecal pellets can also help determine the extent of the infestation, as the size, shape, and color of the pellets vary between different species. This makes them an essential clue in diagnosis, highlighting their importance in a thorough inspection process.

While factors such as the timing of inspection, humidity levels, and the type of structure can play roles in the overall understanding of pest issues, they are not as direct indicators of an existing pest problem as the actual detection of fecal pellets. This makes recognizing fecal pellets a critical element when identifying and diagnosing infestations caused by wood-destroying organisms.
