I used to spend money on all sorts of sprays to keep bugs off my garden—some worked, some didn’t, and a few left my plants looking worse than before. Then I realized something surprising: some of the best pest repellents were already in my kitchen.
If you’re tired of fighting off bugs but don’t want to use harsh chemicals, here’s how I use common spices from my pantry to keep pests away—and how you can do it too.
1. Cinnamon to Stop Fungus and Gnats
Cinnamon isn’t just for toast. It’s a natural anti-fungal and works wonders on damp soil that attracts gnats or mold.
What I do: I sprinkle a thin layer of ground cinnamon on the surface of my seedling trays and potted plants. It keeps fungus gnats away and helps prevent damping off (that annoying seedling disease).
2. Chili Powder or Cayenne to Repel Insects and Critters
Spicy powders mess with the senses of soft-bodied bugs like aphids, as well as rabbits and squirrels who like to snack on leaves.
How I use it:
- Mix 1 tablespoon of cayenne or chili powder with a quart of water and a few drops of dish soap
- Shake and spray directly on leaves (test a small patch first)
What I do: I reapply after rain or every few days during heavy pest seasons. I also sprinkle it dry around plants to keep bigger pests away.
3. Garlic Powder to Repel Leaf-Eaters
Garlic messes with the scent trail of pests like aphids, beetles, and cabbage worms.
How I use it:
- Mix 1 tablespoon of garlic powder with water and a few drops of dish soap
- Spray on affected plants every few days
What I do: I keep this one in a reused spray bottle and use it weekly. It smells strong at first, but it fades quickly.
4. Black Pepper for Ants and Beetles
Black pepper irritates many crawling bugs, especially ants.
What I do: I sprinkle ground pepper around the base of the plants where I’ve seen ant trails. It doesn’t harm the plant and keeps the ants from nesting nearby.
Final Thoughts
You don’t need a cabinet full of store-bought sprays to protect your plants. With just a few kitchen spices and a little consistency, you can keep most pests away naturally.
Once I started using cinnamon, garlic, and cayenne in my garden, the bug damage went down—and I didn’t have to worry about spraying anything toxic on my veggies. So, before heading to the garden store, check your spice rack. It might have everything you need.
