Use peppermint oil and baking soda to repel mice inside the home. Commercial products, such as repellent sprays and pest-deterring garbage bags, are also options that help to control mice populations.
To repel mice inside the home, apply several drops of peppermint essential oil to a cotton ball, and place it in areas frequented by mice. Replace the cotton balls every two weeks or as needed to maintain the scent of the peppermint. Place the cotton balls out of the reach of pets and children. Alternately, homeowners can plant peppermint around the perimeter of the home to repel mice and other pests, or peppermint leaves can be sprinkled in the affected areas of the home. A spray made with 1 teaspoon of peppermint essential oil and 10 teaspoons of water also repels mice.
If lethal repellents are desired, sprinkle baking soda around baseboards and other areas where mice have been observed. Commercial mouse repellents made with plant-based ingredients are also available and should be used according to the directions on the packaging. It is typically necessary to remove food or other items that attract mice for repellents to work properly. Store garbage in lidded containers, and use garbage bags that are designed to repel rodents. Seal cracks and crevices in the home with caulk, or use a stainless-steel pad to block larger entrances, such as unused dryer vents, to prevent pests from entering the home.
