Will Sleeping with Lights on keep Mice away

by Sehrish Vulvox ABC

Mice infestations can be a headache, but there’s a popular belief that leaving the lights on at night can keep them away. Is there any truth to this claim, or is it just a myth? We started by understanding mouse behavior, including their nocturnal habits and their tendency to seek out areas with food, water, and shelter. We then examined the myth that leaving lights on can deter mice, and explained why this belief is unlikely to be true.

Understanding Mouse Behavior

Before we delve into the effectiveness of leaving lights on to deter mice, it’s crucial to understand their behavior. Mice are nocturnal animals, which means they are most active during the night. They prefer dark, quiet places and can enter homes through tiny openings such as cracks and holes. Once inside, they will seek out areas where they can find food, water, and shelter.

The Myth of Sleeping with Lights On

The idea of leaving lights on to keep mice away has been around for a long time. Many people believe that mice are afraid of bright lights and will avoid areas that are well-lit. The theory behind this belief is that mice associate darkness with safety and light with danger. Therefore, if a mouse sees a bright light, it will assume that there is a predator nearby and will stay away.

The Reality of Sleeping with Lights On

While it’s true that mice prefer dark places, leaving the lights on at night is unlikely to deter them. This is because mice are used to living in close proximity to humans and are not typically afraid of light. Additionally, mice have poor eyesight and rely on their other senses, such as their sense of smell, to navigate their surroundings.

Effective Ways to Keep Mice Away

If you want to keep mice away, there are more effective ways to do so than leaving lights on. Here are some tips:

•           Seal Entry Points

Mice can enter your home through even the tiniest of openings. Check your home for cracks, gaps, and holes and seal them with caulk or steel wool. Don’t forget to check your doors and windows, as mice can squeeze through these areas as well.

•           Keep Your Home Clean

Mice are attracted to areas where they can find food and water. Keep your home clean and tidy, and make sure to store food in airtight containers. Don’t leave dirty dishes in the sink, and clean up any spills or crumbs immediately.

•           Set Traps

Traps are an effective way to catch mice that have already entered your home. Place them in areas where mice are likely to travel, such as along walls or near entry points. Be sure to check them regularly and dispose of any dead mice promptly.

•           Call a Professional

If you have a severe mouse infestation, it may be necessary to call a professional pest control service. They can help you identify entry points, seal them off, and develop a plan to keep mice away for good.

Do mice like darkness?

Before we delve into the topic, we must first understand the behavior of mice. Mice are nocturnal creatures, which means they are more active at night. They are also photophobic, which means they are afraid of the dark. Therefore, it is natural to assume that mice prefer darkness over light.

The myth behind sleeping with lights on

Many people believe that sleeping with lights on can keep mice away because they are afraid of the light. However, this is a myth. Mice are not afraid of the light, but they are afraid of predators. Therefore, if they sense danger, they will run away, whether it is light or dark.

How light affects mice behavior

Although mice are not afraid of the light, light can affect their behavior. For example, if there is a bright light in the room, they may avoid it because it hurts their eyes. They may also be more active in dim light, as they feel safer because they can see their surroundings.

The science behind mice and light

Studies have shown that mice can see in the dark, but they are not as effective as seeing in the light. They have a limited range of vision in the dark, which makes them more vulnerable to predators. Therefore, they prefer to stay in dim light, where they can still see but are less visible to predators.


In conclusion, sleeping with lights on may not be an effective way to keep mice away. Although mice prefer darkness, they are not afraid of the light. However, light can affect their behavior, and they may avoid bright light or be more active in dim light. Therefore, it is best to use other methods to keep mice away, such as sealing any holes or cracks in your home and keeping it clean and free from clutter.
