What does drywood frass refer to?

1. Sawdust

2. Pulp

3. Wood fibers

4. Excrement of termites

The correct answer is: Sawdust

Drywood frass refers specifically to the excrement of termites. Termites, particularly drywood termites, consume wood and extract the nutrients they need, excreting the undigested parts in the form of frass. This frass is often composed of tiny pellets that resemble sawdust, which can lead to some confusion. While sawdust is a material created by cutting or grinding wood, drywood frass is distinct because it is biologically processed waste from termites. Understanding this distinction is important for identifying signs of termite infestation, as the presence of frass indicates that termites are actively consuming wood and potentially damaging structures. By recognizing frass as excrement rather than as a byproduct of wood working, individuals can take appropriate actions for pest control and prevention.
