Which of the following is a sign of rodent activity?

Rodent activity can be identified by several typical signs, and when considering all the options together, they all indicate the presence of rodents. Nesting is a clear indicator since rodents often create nests from materials they find in their surroundings, using items like insulation, paper, and fabric. Fecal droppings are another direct sign; the droppings provide evidence that rodents are not only present but also feeding in the area. Chewing is a behavior characteristic of rodents as they need to gnaw on various materials to keep their teeth from growing too long.

When evaluating signs of rodent activity, each of these indicators is significant, and observing one or more of them can confirm rodent presence and lead to more effective management strategies. Hence, recognizing all these signs collectively provides a more comprehensive understanding of rodent activity in a given environment.
