Which of the following is a sign of active rodent activity?

Visible nests made of paper or fabric are a clear sign of active rodent activity. Rodents, such as mice and rats, tend to construct nests in concealed areas where they feel secure. These nests are often made from materials that can be easily shredded, such as paper, fabric, or insulation. The presence of a nest indicates that rodents are not just passing through an area but are actively residing there, using the nest for breeding and shelter.

Seeing only droppings can suggest that rodents have been in the area, but it does not confirm active occupancy, as droppings may remain long after the rodents have left. Weekly food consumption at a feeder indicates that rodents may be foraging; however, it does not necessarily mean they are nesting or living close by. Understanding these behaviors helps in the identification and management of rodent infestations effectively.
