Pest Control Technician Practice Exam 2026 – Complete Prep Guide

A common sign of termite activity is the presence of mud tubes and damaged wood. Termites, particularly subterranean species, create mud tubes as a protective structure while traveling between their nest and food sources. These tubes help maintain moisture and protect them from predators. In addition to these tubes, termites are known to damage wood as they feed on it, which can manifest as hollowed-out areas, discarded wings, and frass (termite droppings). The presence of both mud tubes and damaged wood is a clear indication that termites are active in an area, making them essential signs for pest control technicians to identify when assessing for termite infestations.
