During the inspection for nuisance rodents, which sign may indicate their presence?

Rodent droppings and odor serve as definitive indicators of rodent activity during an inspection. Droppings are a clear and visible sign that rodents have been in a particular area, and their presence can indicate a current infestation. The size and shape of the droppings can also help differentiate between different rodent species, which is crucial for determining the most effective control measures.

Additionally, the odor associated with rodents—often described as a musky smell—can indicate their presence even if the droppings are not immediately visible. This odor may be more pronounced in enclosed spaces where rodents nest or feed. The combination of seeing droppings and detecting this specific smell provides strong evidence of an active rodent problem, prompting the need for further investigation and appropriate pest control actions.

Other potential signs like broken furniture might suggest damage but do not specifically confirm rodent presence, while unusual sounds could be nonspecific, and a pest control smell could be linked to treatments rather than active infestations. Therefore, rodent droppings and odor are the most direct and reliable indicators of nuisance rodent activity.
