What Color Light Keeps Mice Away?

Mice 1

Mice infestations are a common issue for homeowners worldwide. These tiny, uninvited guests can cause significant problems, from damaging property to spreading diseases. As such, finding effective ways to deter them is crucial. One method that has piqued the interest of many is the use of colored lights. But what color light keeps mice away? Let’s delve into the details.


Blue and red lights have been found to be the most effective in deterring mice. Blue light creates an uncomfortable environment for them, while red light makes them feel exposed and vulnerable. However, this method should not be used as the only solution against mice infestations. It’s recommended to combine it with other deterrents and pest control strategies for effective results.

The Impact of Light on Mice

Mice are nocturnal creatures with a heightened sense of sight. While their color perception isn’t as rich as ours, research indicates that they respond differently to various colors of light. It’s suggested that some colored lights can create an unsettling atmosphere for them, which can deter their presence.

Most Effective Colored Lights Against Mice

Blue light has been found to be the most effective color in repelling mice. Mice are sensitive to blue light, and it seems to create an environment that they find uncomfortable, making it an effective deterrent.

Red light is also considered an effective deterrent because mice have a harder time seeing it. This makes them feel exposed and vulnerable, potentially causing them to avoid areas illuminated by red light.

Using Colored Lights as a Deterrent

To use colored lights as a deterrent against mice, consider the following steps:

  1. Install Colored Lights: Place colored LED lights or bulbs in areas where mice are likely to enter or inhabit. This could be near entry points, in basements, attics, or garages.
  2. Create a Light Barrier: Use colored rope lights or LED strips to create a barrier around the perimeter of your house or specific areas where mice are a problem.
  3. Combine with Other Deterrents: Colored lights can be combined with other natural deterrents, such as strong scents like lavender, peppermint oil, or vinegar, to increase their effectiveness.

Remember, mice are intelligent and adaptable creatures. While colored lights can help deter them, they may not be a foolproof solution.

Limitations of Using Colored Lights

While colored lights can be effective to some extent, they are not without their limitations. For instance, mice are nocturnal and prefer darker spaces, so the light inside a house might not be a very effective deterrent. Moreover, the effectiveness of different colors can vary, and the intensity of the light may also play a role.

Combining Methods for Effective Control

While colored lights can be a part of your rodent control strategy, they should not be the only method used. Remove food and water sources, seal entry points, use natural repellents, and consider traps or professional pest control services for more severe infestations.


In conclusion, while there is some evidence that colored lights, specifically blue and red, can deter mice, they are not a standalone solution. However, they can be a part of a broader, more comprehensive rodent control strategy that includes sanitation, exclusion, and professional pest control services when necessary.

Understanding the behavior of mice and how they respond to different deterrents is key to keeping them at bay. So, whether you choose to use colored lights or other methods, remember that consistency and vigilance are essential in successfully controlling these pesky rodents.
