You go to cook dinner and grab the dried bay leaves. Then you notice they expired 2 years ago. Do bay leaves go bad? What about all those other dried herbs and spices in your spice rack? Do dried herbs go bad right after the ‘sell by’ date? And if they can’t be used for cooking anymore, what do you do with them? Wondering what to do with old spices after they expire? Definitely don’t throw them out! We all have a few old herbs and spices in our kitchen, right? Since old spices lose flavor after time, you may not want to cook with them.
How long should you keep herbs and spices? In general, three years is about as long as ground spices last. After their shelf life has passed, find new uses for them instead of throwing them away. They are amazingly handy around the house and yard. Here is a list of the top ways to reuse old spices after they expire.

Use Old Spices to Deter Animals from Your Garden
Certain old spices can help keep animals out of the garden.
This works best if you sprinkle it around the base of plants that are vulnerable and where animals tend to gather.
Some good ones for this purpose include black pepper, chili powder, cloves, garlic powder, red pepper, and onion flakes.
Mix these spices with water in a garden spray bottle for an easy way to apply them over your garden bed or around individual plants.
Old spices work as great as deer prevention if you’re noticing them coming into your garden at night.

DIY spice sachets for drawers
Scented sachet bags are often hung in a closet, or kept in drawers to add a pleasing scent to small spaces. Old spices can be used to create your own sachets using reusable tea bags. Old coffee filters, old socks, or other fabric items may also serve as the sachet material
Put a few teaspoons of dried herbs in the cloth bag and seal it carefully. Then place in a drawer or closet to freshen your clothes.
DIY Christmas ornaments
Cinnamon salt dough makes great homemade Christmas ornaments. You can also use old nutmeg, ground cloves, allspice, pumpkin pie spice, or similar scents.
To make DIY spiced salt dough, combine salt, flour, and spices in a bowl. Make sure each spice is finely ground before adding it to the dough—ground cloves should be as fine as possible.
Add enough water until you have a wet mixture that can easily hold together (a little more or less than ¼ cup) and then knead into a ball with your hands. Roll out to about ¼ inch thickness and cut into shapes.
Use a toothpick to create a hole at the top to hang them with a string. Bake at 350 degrees for one hour, flip over before the end of cooking time so they are evenly baked on both sides.
Let cool, then paint with egg white and cover with glitter if desired. Allow these to dry completely before you hang them on your tree.
Homemade Spice blends
If you have a spice you don’t use much of, consider making it into a spice blend that you WILL use. Many individual spices go into things like ranch dressing or cajun seasoning.
You might find just the seasoning blend you need and the less than potent flavor won’t be quite so noticeable.
Use your old spices to make homemade candles. Melt and pour candles are probably the easiest to make and add your own spices right before pouring.

Make your own laundry refresher out of dried herbs and spices. You can use any combination of herbs, but I like to mix lavender with thyme for a fresh and herbaceous scent.
Plant them in the garden
Did you know that those dried seeds may actually grow into new plants? Try planting your old spices in the garden and see what happens. You may get some interesting new results!
Coriander is the seed from the cilantro plant and mustard seeds may also grow as well once planted outside. This is a great experiment for your kids. Hand them a few fennel and caraway seeds and see what happens!
Revive them in the oven
Warming old spices and herbs in the oven may give them a boost of flavor. This will not work with all herbs, but it is worth a try for things like fennel and caraway. Just put them in an oven-safe dish or pan and heat them on low at 300 degrees Fahrenheit until they are warm to the touch (about 20 minutes).
DIY pain-relieving rub
Certain herbs like cayenne pepper are wonderful in a homemade DIY tiger balm recipe.

- Leave the open jar in the refrigerator to absorb odors and give your fridge a nice clean scent.
While it is fun to find new ways to use old spices, learn how to make spices last longer in your spice cabinet before you have to toss them out.
Over time, spices expire. Sadly, there is no way around the fact that they lose potency over time. Do spices go bad? Well, they aren’t going to make you sick but they won’t taste as good as they did when you first opened the jar. Whether they are whole spices or ground herbs, check expiration dates regularly.
How long do dried herbs last once opened? That varies depending on the type of herb but check the bottle for the best by date. Try to use them in your food before they expire, but if you can’t, there are plenty of creative ways to use them around the house instead!
