Have you ever stepped into your garden only to find aphids sucking the life out of your plants or snails leaving slimy trails while munching away at your prized leaves?

It’s frustrating, to say the least. I’ve tried all sorts of remedies over the years, but one of my absolute favorite natural solutions is hot red pepper.

Yes, the same fiery spice that makes your mouth burn can also keep pests far away from your plants.

How Hot Red Pepper Works Against Aphids and Snails

Hot red pepper, particularly cayenne or chili powder, contains a powerful compound called capsaicin. Capsaicin irritates the soft bodies of aphids and snails, making it extremely unpleasant for them to crawl or feed on treated plants.

Also, many garden pests rely on taste and scent to locate food sources. Hot red pepper masks the natural flavors of plants and leaves a lingering burning sensation, discouraging further feeding.

How to Use Hot Red Pepper Against Aphids

Ingredients:

• 1 tablespoon of hot red pepper powder (cayenne or chili powder)
• 1 quart (4 cups) of water
• 1 teaspoon of mild liquid soap (like Castile or dish soap)

Instructions:

1. Firstly, mix the hot red pepper powder and water in a container. Let it sit for a few hours to fully infuse.
2. Next, strain the mixture through a fine mesh or cheesecloth to remove any solid particles (this prevents clogging your spray bottle).
3. Add the liquid soap and stir well, then pour the solution into a spray bottle and shake well before use.
4. Finally, spray directly onto the tops and undersides of leaves where aphids congregate.

You should reapply every 3–4 days or after heavy rain. Specially, avoid spraying in the middle of the day to prevent leaf burn , early morning or late afternoon is best.

Within days, you’ll notice fewer aphids, and after a couple of weeks, they should completely move on.

How to Use Hot Red Pepper Against Snails

Instructions:

1. Sprinkle a generous amount of hot red pepper powder around the base of plants, raised garden beds, or pathways where snails travel.
2. You can also mix it with crushed eggshells or diatomaceous earth for added effectiveness.

Reapply after rain or heavy watering since water can wash it away. When snails attempt to cross, the powder sticks to their bodies, causing irritation. Most will immediately turn away and search for an easier meal elsewhere.

In addition, if you prefer a spray, the same aphid spray recipe works on snails too. Just apply it directly to plant leaves in the evening when snails are active.

Additional Tips for Best Results

Some plants, particularly delicate ones, may be sensitive to hot pepper spray, so always test on a small section of leaves before spraying the entire plant.

Moreover, hot pepper works well when used with companion planting, diatomaceous earth, or natural predators like ladybugs for aphids and ducks for snails.

Finally, avoid touching your face or eyes after handling hot pepper powder or spray. You can use gloves and wash hands thoroughly afterward.
