Many people like to hang wreaths on their front doors to decorate their homes. And many birds mistake the wreaths as potential places to nest. Since killing a bird that nests in your wreath is cruel and illegal in most communities, try this little trick: Embed some magnets inside the wreath. The magnetic field is disruptive to many birds, making the wreath an uninhabitable place. It's a safe way to keep your wreath nest-free.
