Peppermint is a scent that mice do not like and makes them stay away. Many people will use peppermint oil throughout their house to keep it mice-free.
Mice are pesky household critters that can devastate the home interior and gnaw through some favorite snacks hidden in the pantry. While there are traps and other extermination techniques, using a simple smell, such as peppermint, can keep these creatures away without having to injure or kill them.
Place peppermint oil throughout the home in areas where there has been evidence of mice in the past. Also, place it in areas where the mice may want to frequent in the future, especially if their comfort area has been taken away from them.
