Which of the following tools is NOT recommended for WDO inspection?

The correct choice highlights that fumigation equipment is not typically recommended for Wood-Destroying Organism (WDO) inspections. Fumigation equipment is primarily utilized during treatment processes for pest infestations, particularly when dealing with severe infestations that require gas treatments to eradicate pests throughout a structure. By contrast, the tools commonly employed for WDO inspections focus on identifying the presence of pests or damage caused by pests.

Moisture meters, infrared cameras, and visual inspection tools are essential for detecting conditions conducive to termite activity and assessing existing damage. Moisture meters help identify areas with high moisture levels, which can attract termites. Infrared cameras can reveal temperature differentials that signify pest presence behind walls. Visual inspection tools allow for thorough investigation of accessible areas for signs of infestation and structural damage. Thus, fumigation equipment does not play a role in the initial inspection process and is more suitable for treatment rather than detection.
