What does inspecting for frass indicate during a cockroach inspection?

Inspecting for frass, which is the fecal matter produced by cockroaches, is an important indicator during a pest inspection. The presence of frass signifies that cockroaches are actively feeding and living in the area being inspected. This is a clear indication of an active infestation, as frass is a byproduct of their feeding behavior. When you find frass, it suggests that these pests are present and likely reproducing in the vicinity, rather than indicating a historical issue or something that has since been resolved.

While frass could potentially be associated with old infestations or other pest types, its primary significance lies in indicating the current presence of live cockroaches. This allows for targeted pest control measures to be implemented promptly to address the ongoing issue.
