Mice infestations are a common problem for many homeowners, and finding effective and humane methods of controlling them is essential. There is a common myth that using salt can kill mice, but is this true? In this guide, we’ll explore the truth behind this myth and provide better alternatives for controlling mice.
The Myth of Using Salt to Kill Mice
The idea that salt can kill mice has been around for decades, and many people still believe it to be true. The theory is that mice are unable to excrete excess salt, leading to dehydration and eventual death. While salt can cause dehydration, it would take a large amount to kill a mouse, and it would be a slow and painful death. Additionally, salt can harm other animals, pets, and even plants in your home. Therefore, using salt to kill mice is not only ineffective but also cruel.
Humane and Effective Alternatives to Killing Mice with Salt

Fortunately, there are several humane and effective methods for controlling mice that do not involve killing them. These methods are also safer for pets and children in your home.
A. Natural Repellents for Mice
Natural repellents for mice are a popular and effective way to deter mice from your home. Peppermint oil, vinegar, and cloves are all examples of natural repellents that mice find unpleasant. These natural repellents can be used in various ways, such as spraying them around the home, soaking cotton balls and placing them around the home, or planting certain herbs in your garden.
One study conducted by researchers at the University of Arizona found that mice avoided areas that had been treated with peppermint oil. The study also found that mice exposed to peppermint oil were less likely to reproduce, suggesting that natural repellents can be an effective long-term solution for controlling mice.
B. Traps for Capturing Mice
Traps are another effective way to control mice without killing them. Live-catch traps and glue traps are both options for capturing mice humanely. With live-catch traps, you can release the mouse outside of your home, while glue traps can be used to catch and release the mouse later. Snap traps can also be used, but it is important to ensure that they are set up in a way that does not harm other animals or pets.
It’s important to note that when using traps, you should always check them regularly to ensure that the mice do not suffer unnecessarily. You should also release the mice as quickly as possible after capture.
C. Electronic Repellents for Mice
Electronic repellents are an effective way to deter mice without harming them. These devices emit high-frequency sound waves that mice find unpleasant, causing them to avoid the area. Electronic repellents are a safe and humane way to control mice, and they are also effective in preventing future infestations.
Electronic repellents can be purchased online or at your local hardware store. They are easy to use and require little maintenance. However, it’s important to note that electronic repellents may not be effective in large areas or in areas with a high concentration of mice.
Professional Extermination Services

In some cases, professional extermination services may be necessary, especially if you have a severe infestation that cannot be controlled with other methods. Professional extermination services can use various methods, such as traps or poisons, to control the mice in your home. However, it is important to note that these methods can be harmful to pets and children, and they are not as humane as other methods.
When considering professional extermination services, it’s important to do your research and choose a company that uses humane methods whenever possible.
Prevention is Key
Preventing mice from entering your home in the first place is often the best way to control an infestation. The following are some tips to prevent mice from entering your home:
- Seal any cracks or holes in your home’s foundation or walls. Mice can enter through even the tiniest of openings, so it’s important to be thorough.
- Store food in airtight containers. Mice are attracted to food, so keeping it out of reach can deter them from entering your home.
- Keep your home clean and tidy. Clutter provides a place for mice to hide, so it’s important to keep your home as clean and tidy as possible.
- Trim back any trees or shrubs that touch your home. Mice can use these as a pathway to enter your home.
Safety Precautions When Handling Mice

When using traps or other methods to control mice, it’s important to take safety precautions to avoid injury or disease. Mice can carry various diseases, such as hantavirus and salmonella, so it’s important to wear gloves when handling them.
If you’re using live-catch traps, make sure to release the mice as quickly as possible and at a safe distance from your home. If you’re using glue traps, be careful when removing the mice to avoid injuring them.
Conclusion
In conclusion, using salt to kill mice is not only ineffective but also inhumane. There are several better alternatives, including natural repellents, traps, electronic repellents, and professional extermination services. It’s important to choose a method that is safe for pets and children and that effectively controls mice in your home. Preventing mice from entering your home in the first place is often the best way to control an infestation, but if you do have an infestation, using humane and effective methods can help you control it. By following the tips in this guide, you can maintain a mouse-free home without resorting to harmful or inhumane methods.
