What are common signs of rodent infestation?

The presence of droppings, gnaw marks, and nests is indicative of a rodent infestation. Rodents, such as rats and mice, are known to leave behind droppings, which can range in size depending on the species. These droppings are often found near feeding sites and travel routes. Additionally, rodents have a tendency to gnaw on materials such as wood, plastic, and wiring, leaving noticeable gnaw marks that serve as a clear sign of their activity. Nests, typically made from shredded paper, fabric, or insulation, are another strong indicator of rodents taking up residence in an area. Identifying these signs can help homeowners and pest control professionals determine the presence and extent of an infestation, allowing for appropriate control measures to be implemented.

The other options do include signs of pest activity, but they may not be as specifically indicative of rodent infestations. Tracks and nests in attic spaces could suggest the presence of various animals, but tracks alone aren't definitive without other signs. Holes in walls and furniture scratching might indicate various pests, including insects. The presence of pet hair, while it might signal an animal's presence, is not specific to rodents and could lead to confusion in identifying the type of infestation.
