1. Mix your citrus rinds with half a bottle of beer, half a pack of yeast, and a quart of warm water. Let it ferment for two days, place it in a shallow pan and then set the pan in your garden. Snails and slugs will either drink themselves to death or drown.
2. Orange and lemon peels scattered around in the garden will keep dogs and cats out.
3. Orange peels are toxic to ants. Put some ground up orange peels on the top of an ant mound and cover ...bye bye ants.
4. Feed your birds by filling up empty orange and grapefruit half's with a mixture of birdseed and suet: then hang it by a string in the tree, or just tack it to the tree.
