Mice tend to avoid places where they cannot find food, have no hiding spots, entry points are sealed, and regular human activity is present. Although peppermint oil, strong odors, or some natural methods are often claimed to repel mice, the lasting solution is environmental control. Food should be stored in sealed containers, crumbs should be cleaned, garbage should be removed regularly, and entry points around walls, door gaps, and pipes should be sealed. Cluttered storage areas, cardboard piles, and unused items can provide hiding places for mice. The most effective strategy is not relying on smell but eliminating food, water, and shelter sources.
