What you need
Peppermint Oil
Cotton balls
Instructions
Mice do not like strong odors and peppermint oil is not their favorite.
Add a few drops of peppermint oil to cotton balls and place the balls around entry ways. If you have holes or openings, fill them with aluminum foil as mice can not chew through foil.
Remember to refresh the balls often to keep up the scent barrier.
How is this a “craft”? “EO drops on cotton balls, put where mice have been found.” Which, by the way, doesn’t work particularly well.
like many projects you post there are no pictures of thye finished item, so I generally am not interested in trying it.
