What is a key behavioral sign of a rodent infestation?

A key behavioral sign of a rodent infestation is frequent daytime sightings. Rodents, such as mice and rats, are generally nocturnal creatures, meaning they are most active during the night when they are less vulnerable to predators. However, if there is a noticeable increase in daytime activity, it can indicate a significant infestation, especially if food sources are scarce or if the population pressure forces the rodents to venture out during the day.

Typically, as rodent populations grow, they may be seen during daylight hours, which can be alarming and indicative of a larger problem. This daytime activity could also mean they are more accustomed to human presence or that their usual hiding spots have been compromised.

In contrast, while activity at night is typical for many rodents, it does not necessarily indicate an infestation. The use of nests is common among rodents but is more of a nesting behavior than a direct indicator of their presence in terms of quantity and infestation severity. Low visibility is misleading, as it does not provide any concrete evidence of an infestation. Thus, frequent daytime sightings are a strong signal of an increased rodent population in an area.
