Before you chuck that jar of spice that’s been sitting in your cabinet for longer than you can remember, consider these tips. Spices that aren’t worth eating may still have some use around your house and garden.

The good news is that spices don’t spoil in such a way that will make you sick, but they can lose their flavor. Different spice sellers offer different timelines for shelf life. Spice Island gives ground spices two to three years and whole spices three to four years. However, the best way to know if the spices on your shelf are still good is by color and smell. If either has faded, it may not be worth cooking.

Even if a spice doesn’t smell as strong as it once did, heat can release the last of its volatile oils, giving off a lovely aroma. Boil a pot of water on your stove and add whichever spices you want your house to smell like—cardamom, cinnamon, cloves or ginger. You can also throw in some citrus peels.

2. Spicy soap

The granular texture of ground cloves and pepper can act as a gentle exfoliator in your next batch of homemade soap.

3. Deter animals

Spicy peppers like cayenne or chili are good for keeping critters away from bulbs. Just sprinkle the spice on the bulb itself or the topsoil around it. Black pepper can also be used to fight ants. Keep in mind that older spices may be less potent, and you may want to pepper plants lavishly.

4. Nontoxic fungicide

Spices can even be used for art projects at home. Simply combine each spice with a base, such as water or glue, to create a paint-like mixture. Then paint away. The reds, lights browns, and yellows of many spices lend themselves perfectly to autumnal scenes.
