Where are earwigs commonly found?

Earwigs are commonly associated with damp environments and often seek shelter in places that provide moisture and protection. They are typically found under door mats, where they can access moisture, and in tree bark, which offers a natural habitat that protects them from predators and environmental extremes. These locations allow earwigs to thrive, as they prefer dark, humid areas that support their lifestyle, making option B the most accurate answer.

Attics and basements may not be a popular choice for earwigs since these areas may not consistently provide the moisture they seek. Inside human dwellings, while they can occasionally be found, they are not as frequently established there compared to their preferred outdoor habitats. Similarly, rooftops and gutters are less conducive to the moist environments earwigs favor, making option B the most aligned with their typical behavior.
