I'm afraid I have been rather lazy lately and have left food scraps, biscuit crumbs and fruit peelings in the wastebasket for days on end. As a result, ants have decided to call my apartment home. I don't like to use pesticides or chemicals so I was thinking if anybody know of any natural substances that can repel ants. I'm thinking along the lines of something I can burn or just keep in the apartment, that will emit a fragrance that will repel ants. That way, I can be lazy and still not have ants.
