A common symptom of a rodent infestation includes noises in walls or ceilings, droppings, or gnaw marks. Rodents are known for their activity during the night, which may result in sounds that can be heard as they scurry through walls or ceilings. Additionally, their droppings can often be found in areas where they are active, serving as a clear indicator of their presence. Gnaw marks on various surfaces, such as furniture, wires, or food packaging, also signal that rodents are present, as they need to gnaw to keep their teeth trimmed and sharp.

Visible nests, while relevant, may not always be present or easily observable, especially in hidden or inaccessible areas. Excessive insect activity indoors could indicate various pest problems but is not a direct symptom of a rodent infestation. An unusual odor in the attic might occur due to decomposing rodents or their excrements, but it is not as immediately identifiable as the combination of sounds, droppings, and gnaw marks that distinctly point toward a rodent problem.
