What scents deter mice?

The scent of peppermint helps deter mice. Having a fresh peppermint plant in the house or placing cotton balls soaked in peppermint oil near areas where mice enter the home helps keep the rodents away.

The scent of peppermint helps cover up the pheromone trail left by mice in the house. If mice are already in the house, it is necessary to leave more peppermint-soaked cotton balls in more places than just where mice enter the home. Leave cotton balls in places mice hide, such as closets, cupboards, cabinets and bedrooms. Another smell that deters mice is the smell of a cat, because mice are naturally fearful of cats.
