Wood Destroying Organism (WDO) Home Inspection 2025 – 400 Free Practice Questions to Pass the Exam

Subterranean termites require high relative humidity to thrive because they are particularly sensitive to drying out. They build their nests in soil, which provides the necessary moisture for their survival. This environmental condition is crucial as it allows them not only to live and reproduce but also to effectively forage for wood. Their behavior includes creating mud tubes to maintain a humid microenvironment while they travel between their nest and food sources. This reliance on high humidity makes areas with consistently moist conditions more susceptible to subterranean termite infestations. On the other hand, options such as access to dry wood or direct sunlight are not conducive to their survival, as these conditions can lead to dehydration and threaten their colonies. Additionally, while stable temperature can aid in their survival to an extent, it doesn't directly meet their physiological need for moisture, making high relative humidity the most vital characteristic for their thriving.
