Wood Destroying Organism (WDO) Home Inspection Practice Exam

Where are drywood termites commonly found due to climate conditions?

1. In the midwestern states

2. In northern states

3. In certain southern and western states

4. In mountainous regions

The correct answer is: In certain southern and western states

Drywood termites thrive in warmer climates, which is why they are typically found in specific southern and western states. The reason for their preference for these areas stems from the warm temperatures and lower humidity levels that are conducive to their survival and reproduction. Unlike subterranean termites, which require soil moisture, drywood termites can live within the wood itself and do not need contact with the ground for moisture. This adaptability allows them to infest homes and structures in regions where the climate is more favorable for their lifecycle and feeding habits. Furthermore, these conditions in the southern and western states not only provide suitable temperatures but also an abundance of cellulose materials, like untreated wood and wooden structures, which serve as food sources for drywood termites. In contrast, the colder climates of the midwestern and northern states present environmental challenges such as freezing temperatures that can inhibit the survival of these pests, making them less prevalent in those regions. Mountainous regions also experience temperature fluctuations that are not as stable or conducive to drywood termite populations compared to the warmer coastal or subtropical areas they prefer.
