During home inspections, it is commonly accepted to interpret a moisture level of 20 percent or higher as an indicator of potential subterranean termite activity. Moisture meters are excellent tools that can increase the effectiveness and quality of your inspection by providing customers with actual documented numbers, rather than just eyeballing a moisture problem. Good-quality moisture meters can be non-destructive and used on a variety of surfaces.
Assessing moisture level changes (or lack thereof) pre- and post-treatment — or during a follow-up inspection — can help determine whether further investigation is warranted. In my experience, homeowners tend to be more willing to resolve moisture issues when a moisture meter is used, especially one that broadcasts an alarm warning about high moisture levels.
