Salt can act as a deterrent or, in specific commercial products, a lethal agent by causing severe dehydration, but using plain salt is generally ineffective and difficult, as mice aren't naturally drawn to it and can find water, while some salt-based rodenticides work by using corn gluten meal with salt to stop thirst signals. Epsom salt (magnesium sulfate) offers a stronger scent deterrent, but regular table salt isn't a reliable DIY mouse killer or blocker.
It can also be used to repel rodents due to its acrid smell. Sprinkling Epsom salt onto your trash can lid or around areas where rodents are known to burrow creates a protective boundary that can keep them away.
Mice absolutely detest the smell of peppermint. Cotton balls dabbed with peppermint oil can work well to repel mice, as can dried mint sachets. Just place oil-soaked cotton or mint-scented sachets in problem areas, refreshing as often as needed.

Amish communities get rid of mice using a mix of traditional, low-tech, and natural methods, focusing heavily on prevention (sealing entry points, removing food sources) and humane trapping, often with handmade cage traps, while also using strong scents like peppermint oil or cayenne pepper as repellents, sometimes alongside cats for natural pest control. They avoid modern poisons to maintain their lifestyle and focus on practical, sustainable solutions.
To 100% get rid of mice, you need a multi-pronged approach: Exclusion (seal all entry points with steel wool/mesh), Sanitation (remove food/water sources), and Trapping (use many snap traps with peanut butter along walls). For persistent issues, consider professional help, but combining sealing gaps, eliminating food, using strategic traps/bait stations, and maintaining cleanliness offers the best chance for complete eradication.

Mouse traps are one of the most effective ways to get rid of mice that have taken up residence inside your home. Place mouse traps in the more vulnerable areas of your house, like along walls and behind trash cans.
Mothballs. Mothballs are another effective mouse prevention method due to their strong smell, but Liakopoulos cautions against using mothballs if you have pets or children. “The chemicals in mothballs (naphthalene) are toxic to mice, but also dangerous to humans and pets,” he says.

Cloves – The intense, spicy fragrance of cloves can be irritating to pests and drive them away from treated areas. Eucalyptus oil – The menthol-like aroma of eucalyptus can be too strong for these little critters to tolerate.
Bleach has a powerful and unpleasant smell, and that will keep mice away in the short term. However, that smell doesn't stay around very long without a great deal of the product being applied to an area. As a result, you would need to spread around a lot of bleach to maintain an environment that would repel mice.
Q: What do Epsom salts do to mice? A: Epsom salts can act as a natural deterrent. Sprinkling them around entry points and areas of rodent activity may discourage mice due to the texture and taste.
However, one mouse will almost always lead to an infestation if control methods are not put in place.
