You have to be kidding!?!?!?
Peppermint oil is being touted on the internet as being a natural way to repel mice from your home. While mice may not like the smell of candy canes, peppermint oil is not an effective way to control mice.
Why doesn't peppermint oil repel mice?
Does your home smell like a candy factory? Peppermint oil dissipates quickly, and the oil needs to be replenished a couple times a week to maintain a high odor level. It requires a lifetime commitment of accessing your attic space, basement, and other areas of mice activity.
The reproductive power of mice will overwhelm your commitment to the process of replenishing peppermint oil a couple times a week. The mice will win the battle.
