What is an unusual behavior that might indicate rodent activity?

Nocturnal scurrying sounds are a strong indicator of rodent activity because many rodents, such as mice and rats, are primarily active during the night. Their movements can create distinct sounds as they navigate through their environment, searching for food or shelter. This behavior is particularly noticeable in quiet settings where the sounds of rustling or scurrying are more easily heard.

In contrast, rapid buzzing sounds may originate from insects or machinery, rather than rodents. Frequent visits from birds are unrelated to rodent behavior, as birds typically do not signify rodent presence. Lastly, while a frequent dropping of crumbs might suggest food activities, it does not specifically indicate rodent activity unless combined with other signs, such as droppings or gnaw marks. Therefore, the presence of nocturnal scurrying sounds is a clear indicator that warrants further investigation for potential rodent infestations.
