In which regions are drywood termites commonly found due to climate?

Drywood termites are predominantly found in certain southern and western states due to the warm, dry climates that suit their survival and reproduction. These termites thrive in areas with temperatures that allow their colonies to flourish, typically experiencing minimal cold weather, which can affect their population.

Regions like California, Florida, and other areas in the southern U.S. provide the appropriate environmental conditions, such as warmth and humidity, that support drywood termite activity. Their ability to live in wood without needing to contact the soil makes them more common in these specific climates compared to other regions that may have harsher or colder weather conditions, which are less conducive for their survival.

This geographical spread is reflected in the fact that the insects are not uniformly distributed across the entire United States, as indicated by the other options. Therefore, the focus on particular southern and western states illustrates the importance of environmental factors in the distribution of drywood termites.
