Mice detest the minty aroma of these all-natural Mouse Magic repellent sachets. Place them wherever rodents are a problem — kitchen, pantry, cellar or shed — and pests will be repelled for up to 30 days. Perfect for hard-to-reach spots such as inside dropped ceilings and behind large appliances. Keeps mice out of your car's engine compartment, too. Safe for use around kids and pets.
