Get Rid of Slugs with Grapefruit Rinds! You can use a variety of fruit rinds for this, including orange, lemon, and lime rinds, cantaloupe or honeydew melons that you've halved and scooped the fruit from, or winter squash rinds you've halved and hollowed out. Don't spend any extra money next time you have to deal with a slug problem. Check your produce drawer or root cellar instead!
