If mice are driving you mad but you can't stand the thought of killing them off with poison and traps, you can instead deter the critters with the natural method of peppermint. While store-bought peppermint-scented fresheners may not do the trick, you can hook up your own little pockets of peppermint to keep the mice at bay.
Oil on Cotton
Trek to your health food store for a bottle of peppermint essential oil. This is an effective base ingredient for many of the deterrents. Simply soak some standard cotton balls in the oil and cram them into the crannies where mice are known to roam. The cotton will lose its scent fairly quickly, so make sure to replace often if mice continue to be problematic.
Oil, Leaves and Cloves
For a solution with a little more staying power, mix a small amount of the peppermint oil with fresh peppermint leaves and fresh cloves. Place the mixture into small cheesecloth bags or sachets. Place these strategically in problem areas. The mouse-repelling scent will be stronger than straight-up peppermint and last a bit longer than the cotton.
Another way to use peppermint is to grow it fresh in pots around the home. Keeping these pots in the kitchen may help ward off mice to some extent, and you can make them even more effective by mixing the leaves with oil and cloves as stated above. This not only will add a fresh scent to your home but will also ensure you have a steady supply of fresh mint for your tea, desserts and mice-repelling uses.
Mix some peppermint essential oil with a carrier oil, which is also sold at health food stores, to create a spray deterrent. Spritz along baseboards, in holes and other mice-happy areas.
