True or False: Pelleted wood frass attached to joists or headers is considered visible evidence of termites.

Pelleted wood frass, which is the droppings produced by termites, can indeed serve as an indicator of termite presence. However, the statement that it is considered visible evidence of termites in all contexts is misleading. Wood frass typically indicates past activity rather than current infestation; hence, it may not be sufficient to classify it as visible evidence of current termite activity.

In pest management, evidence of termites is typically defined by active signs, such as live termites, galleries, or signs of recent damage. Pelleted wood frass, especially if found in locations without evidence of current activity, may simply indicate prior infestations without confirming ongoing problems. Therefore, the statement is best regarded as false unless there are additional signs of current activity or ongoing infestation.

Understanding this distinction is crucial for pest control professionals, as effective management of termite issues requires not just identifying past activity, but also evaluating the present condition to determine the need for treatment or intervention.
