Which sign of rodent infestation relates to their feeding habits?

Gnaw marks are directly associated with rodent feeding habits because rodents have continuously growing teeth that require constant gnawing to keep them at an appropriate length. As they search for food, they may chew on various materials, including wood, plastic, and even electrical wiring. These distinctive marks are often left behind on surfaces where the rodents have been feeding or accessing food sources.

In contrast, footprints and paw prints are more indicative of rodent movement rather than feeding, as they primarily provide evidence of travel paths rather than direct feeding activity. Scent trails, commonly used for communication and navigation among rodents, do not specifically indicate feeding habits but rather the presence of rodents in an area. Therefore, gnaw marks serve as the most reliable sign of rodent infestation in relation to their feeding behavior.
