Natural insecticide spray recipes

There are several homemade insecticides that you can make with natural ingredients to protect your plants from pests without resorting to chemicals. Here are some easy and effective recipes:

1. Garlic insecticide
Garlic is a natural insect repellent and has antibacterial and antifungal properties.

Recipe: Crush 3 cloves of garlic and mix them with 1 liter of water. Let the mixture sit for a few hours or overnight. Then, strain it and add 1 teaspoon of neutral soap to increase effectiveness. Spray the mixture on affected plants, especially on the underside of leaves where pests usually hide.
2. Potassium soap (or castile soap) insecticide
Potassium soap or castile soap is a safe and gentle way to eliminate insects such as aphids, mealybugs and mites.

Recipe: Mix 1 tablespoon of liquid castile soap (or potassium soap) with 1 liter of water. Spray the mixture on the affected plants, making sure to cover the leaves, stems and roots if possible. The soap dissolves the membranes of the insects and eliminates them without harming the plants.
3. Chili and pepper insecticide
The combination of chili and pepper is an excellent insect repellent.

Recipe: Mix 1 tablespoon of chili powder or red pepper with 1 liter of hot water. Let it rest for a few hours and strain it. Add 1 teaspoon of neutral soap so that it adheres better to the plants. Spray the mixture on the plants, especially where pests are found. The spiciness irritates insects and scares them away.
