What are some observable signs of rodent infestation in a structure?

The presence of droppings and gnaw marks is a clear indicator of rodent infestation in a structure. Rodents, such as mice and rats, leave droppings that are small, dark, and pellet-shaped, often found in areas where they travel or nest. Additionally, gnaw marks on walls, furniture, or food packaging are also strong signs of their presence, as rodents continuously chew on materials to file down their ever-growing front teeth. Observing these signs can help in early identification of an infestation, allowing for timely management and control measures to be taken to prevent further damage and health issues associated with rodents.
