Which pest is known for its twelve distinct body segments?

The correct answer is silverfish, which is known for its distinctive body structure characterized by twelve distinct body segments. This segmentation helps identify silverfish among other household pests. The segmented body contributes to their ability to move quickly and maneuver through tight spaces, which is often why they can be found in various areas of the home, especially in damp places like basements and bathrooms.

In contrast, other pests listed, such as carpet beetles, Indian meal moths, and drugstore beetles, do not have this unique segmentation. Carpet beetles have rounded bodies covered with scales, which gives them a different appearance. Indian meal moths possess a more typical insect body structure with notable wings, while drugstore beetles are also more rounded and recognizable by their elongated snouts. These differences in physical characteristics help in correctly identifying the silverfish as the only pest in the options given that features the twelve distinct body segments.
