🔥 RED PEPPER: The Natural Pest Killer Most People Don’t Know About

Red pepper — especially hot chili or cayenne pepper — isn’t just a spice for cooking. Its fiery compound capsaicin makes it a natural pest deterrent that gardeners and DIYers can use around the home and garden to keep insects and small critters away without resorting to harsh chemical pesticides.

🌶️ Why Red Pepper Works Against Pests

Capsaicin is irritating to many pests: Insects like aphids, snails, slugs and some crawling bugs dislike the heat and smell of hot pepper, so they stay away from treated plants. (One Million Ideas)
It’s non‑toxic (when used properly): Unlike many chemical pesticides, a red pepper spray is biodegradable and generally safer for kids, pets and the environment. (green garden)
Easy to make at home with ingredients you probably already have. (One Million Ideas)

🛠️ DIY Red Pepper Pest Spray

Here’s a simple, effective recipe: (One Million Ideas)

Ingredients

2 tablespoons hot red pepper powder (cayenne or chili flakes)
1 quart (about 1 liter) water
1 teaspoon liquid soap (dish soap works — it helps the spray stick to leaves)
Spray bottle

Steps

Boil the water and stir in the red pepper powder.
Let the mixture cool completely.
Strain out the solids (a sieve or cheesecloth).
Add the liquid soap and mix well.
Pour into a spray bottle and shake before use.
Spray directly onto plant leaves — especially underside where pests hide.

Tip: Reapply every 5–7 days or after rain. (One Million Ideas)

🐌 Barrier Method for Crawling Pests

Instead of spray, you can also sprinkle a thin line of dry red pepper powder around the base of plants.
Snails, slugs and crawling insects generally avoid spicy barriers because the capsaicin irritates them as they crawl over it. (Outdoor Guide)

🧄 Boost the Effect (Optional)

For tougher pests like aphids or beetles, you can combine red pepper with garlic in the spray: simmer garlic and hot pepper in water before straining. Garlic itself is a strong pest deterrent too. (One Million Ideas)

⚠️ Precautions & Best Practices

✅ Avoid contact with eyes and skin — capsaicin can irritate, so wear gloves and avoid spraying on windy days. (One Million Ideas)
✅ Red pepper spray repels and deters many pests, but it doesn’t instantly kill every insect — persistence and reapplication help. (green garden)
✅ Test on a small area first — some plants can be sensitive and show leaf burn if sprayed heavily in hot sun. (Environmental Research Institute)
✅ Reapply after watering or rain to maintain protection. (One Million Ideas)
