Mice repellent peppermint oil - Peppermint oil looks sounds like a fantastic idea for mouse control. Peppermint oil is organic and isn't offensive to the people sharing the treated area.

The odor will be too powerful for them to willingly approach the cotton, but it isn't a smell that will raise alarm. Mice don't have any natural aversion to peppermint and won't associate the odor with anything dangerous. If forced to, mice walk around the offending cotton ball or push it from the hole. Peppermint oil is the naturalist's effort at precisely the identical repellent concept involved when using mothballs for rodent control. If you need to eliminate mice from your house or business, they ought to be trapped and removed.
