There are several smells that mice dislike and can be used as natural repellents. Here are some of them:

• Peppermint oil
• Cinnamon
• Vinegar
• Citronella
• Ammonia
• Bleach
• Mothballs

Peppermint oil and cinnamon can be used as a spray or sprinkled around the house. Vinegar can be used as a spray or soaked in cotton balls and placed in areas where mice might be entering the home. Citronella can be used as a spray or candle. Ammonia and bleach can be used as a cleaning solution or soaked in cotton balls and placed in areas where mice might be entering the home. Mothballs can be placed in areas where mice might be entering the home, but they should be used with caution as they can be toxic to humans and pets.
