Rodents are predominantly nocturnal creatures, which means they are primarily active at night. However, in the case of heavy infestations, their behavior can change. High population densities can lead to increased visibility during the day, especially if food sources are scarce or if their nest has been disturbed. Therefore, in environments where resources are plentiful and competition is high, it is common for rodents to be seen at any time of day, including during daylight hours. This flexibility in their activity level makes them more detectable in the presence of an infestation. Understanding this behavior is crucial for effective rodent control and management strategies, as it indicates that both nighttime and daytime surveillance may be necessary to assess the extent of an infestation.
