Nocturnal creatures

mice are nocturnal creatures, so they are most active between dusk and dawn. They don't usually like bright lights, but a mouse may sometimes be seen during the day, especially if its nest has been disturbed or it is seeking food. Seeing them in the day also can indicate a large infestation in a home. Thus, seeing one or more rats during the day is often a likely sign of an infestation in your home or commercial property. On the other hand, it is also possible that there is just one rat that you're seeing during the day.Rats and mice are nocturnal with most activity taking place between approximately one half hour after sunset to about one half hour before sunrise. These creatures are sensitive to bright lights and have poor eyesight. Survival instincts cause them to avoid larger animals and being active at night helps mice avoid being seen by predators, as well as people. Because mice avoid danger, they may be scared off by bright, flashing lights or loud noises.
