The activity patterns of Rattus norvegicus and Rattus rattus, commonly known as brown and black rats respectively, are primarily nocturnal. This means their peak activity, including foraging and exploration, occurs during the hours of darkness. While generally active at night, their emergence is influenced by a range of environmental and behavioral factors.
Understanding the temporal habits of these rodents is crucial for effective pest management strategies. Knowledge of their active periods allows for targeted placement of traps and bait, maximizing efficiency and minimizing potential harm to non-target species. Historically, awareness of their patterns has been vital in preventing disease transmission, as rats can carry various pathogens detrimental to human health.
