Peppermint is the most commonly cited smell that may keep mice away, and other strong scents like clove, eucalyptus, cinnamon, vinegar, ammonia, and citrus are also often used. These smells can help deter mice for a short time, but they usually work best as part of a broader pest-control approach rather than a permanent fix.

Quick Scoop

  • Best-known option: peppermint oil.
  • Other common deterrents: clove oil, eucalyptus, cinnamon, vinegar, ammonia, citrus, and cayenne/chili scents.
  • Important caveat: smells alone usually do not solve an infestation; sealing entry points and removing food sources matters more.

What to try

  1. Put cotton balls with peppermint oil near entry points, under sinks, and behind appliances.
  1. Use clove or cinnamon near cabinets, baseboards, and other places where mice travel.
  1. Keep areas clean and store food in sealed containers so mice have less reason to stay.

Safety note

Avoid using harsh chemicals carelessly, and be cautious with things like ammonia, bleach, and mothballs around pets and children. If mice keep coming back, the most effective next step is professional pest control or thorough exclusion work.
