How to Deter Aphids Using Hot Pepper and Garlic Spray?

Aphids may be tiny – but their impact can be serious. These pests multiply quickly and weaken plants by feeding on their sap.
They also leave behind honeydew, a sugary waste that attracts ants and leads to black mold. To stop the damage early, try this spicy, natural remedy made with garlic and red pepper.
The materials include:
- Garlic pieces: 200 grams
- Hot red pepper powder: 1 tablespoon
- Warm water: 1L
- Water for dilution: 10L
You can make the solution easily at home – with just a few simple steps below:
- Prepare a clean container.
- Put garlic and the red pepper powder inside.
- Pour warm water over the mix.
- Allow it to sit for around 6 hours.
- Strain the mixture.
- Add 10 liters of water to dilute the mixture.
- Pour the mixture into a spray bottle.
- Spray the solution on your plants. Spray the bottom of the leaves – aphids often hide there.
Try the spray on one leaf first. This helps keep delicate plants safe.
Never spray in strong sunlight or heat. Morning or late afternoon works best to avoid burning the leaves.
How to Keep Snails Away with Hot Pepper and Diatomaceous Earth Mix

Snails may move slowly, but their damage happens fast. Young leaves and seedlings are often the first to go.
Instead of reaching for salt, which harms both soil and plants, try this simple, natural mix using red pepper and diatomaceous earth.
The needed materials:
- Hot red pepper powder: 1 tablespoon
- Ground black pepper: 1 tablespoon
- Food-grade diatomaceous earth: 1 kilogram
Just follow the guide – and you have an effective mixture to repel snails:
- Combine all ingredients in a clean container. Stir until the mixture looks even and well blended.
- Sprinkle the powder in a circle around plant bases or around garden edges. As a result, you can create a physical barrier that snails avoid.
- Focus on moist areas or snail pathways to improve results.
Why Diatomaceous Earth Works Against Pests

Diatomaceous earth comes from fossilized algae and holds fine, sharp-edged particles. These tiny fragments harm a snail’s soft tissue, leading to moisture loss and death.
This natural material does not harm plants or helpful insects when used correctly.
- Reapply after heavy rain or every 3 weeks. Water washes the powder away, making the barrier less effective.
- Keep the mixture on the soil surface. Avoid putting it directly on stems or leaves to protect plant health.
