What is an indicator of a rodent problem in a home?

The presence of droppings, gnaw marks, and unusual noises at night is a strong indicator of a rodent problem in a home. Rodents are often nocturnal, which explains why unusual noises might be heard primarily at night. Their droppings and gnaw marks on food packages, walls, or furniture are clear signs of their activity and the potential presence of a nest. This combination of evidence helps homeowners recognize an infestation and take appropriate action.

In contrast, fluttering sounds during the day may be indicative of birds or other animals rather than rodents. Empty food packages can signify that food has been accessed, but they do not directly confirm the presence of rodents without accompanying signs. Prolonged silence, on the other hand, does not provide any evidence of a rodent problem since it does not indicate any activity is occurring. Thus, the best indicator is the combination of droppings, gnaw marks, and nighttime noises.
