What type of areas are typically moist and may harbor pests like millipedes?

The correct answer focuses on basements, which are common areas that tend to have higher moisture levels due to poor drainage, humidity, and limited ventilation. These conditions create a favorable environment for various pests, including millipedes, which thrive in damp conditions.

Basements often have dark, undisturbed spaces where moisture can accumulate, making them an ideal habitat for pests seeking refuge from dryer, more exposed environments. In contrast, high-temperature areas, dry arid regions, and sunlit spots typically do not provide the necessary moisture that facilitates the survival and proliferation of pests like millipedes, as they prefer cooler and more humid habitats. Therefore, basements are aptly noted for their propensity to harbor moisture-loving pests.
