Keeping the lights on is not the best way to deter mice from entering rooms. Mice are movers who can get from one area to another to hide once again in a dark, comfortable space.

If the lights are on and mice happen to be caught in the middle of the room, they may disappear as fast as a blink of an eye. When the lights are on, mice will try to hide inside walls, crawl spaces or even in ceilings. They are nocturnal creatures and prefer to be more active in the dark.

Mice do not prefer to come out when the lights are on. They are nocturnal and more active between dusk and dawn. Mice don’t enjoy bright lights, but it will not deter them enough to keep them away from the shortest distance that leads to their shelter.

If a nest is located in a straight line between one spot where they are hiding in a well-lit room, they will take their chances in scurry right through the bright room. If they are seeking food in a well-lit location, they will take their chances as well and try to snatch what is available to them to bring back to their nest.

Ammonia keeps mice away because it resembles the odor of predators. No matter which option you choose, know that an odor they hate would keep mice away much better than turning the lights on.
