Natural pest repellents can be crafted from certain ingredients that insects find repulsive. You can harness this knowledge to create eco-friendly pest control products that are safe for both human health and the environment.
Ginger, Garlic, and Chili Pest Repellent
Ginger, garlic, chili peppers, and onions possess a spicy kick that acts as a “nemesis” to garden-variety pests. You can harness the power of these ingredients to create a natural pest repellent for your garden.
To make an effective natural pesticide, you’ll need 1kg each of garlic, chili peppers, and ginger. Finely chop or grind these ingredients, then place them in an airtight container. Pour in 3 liters of alcohol, seal the container, and let it steep for 15 days.
Alternatively, you can use a single ingredient like chili peppers, onions, garlic, or ginger, infusing them in alcohol at a 1:1 ratio. However, combining these ingredients will yield more potent results.
Use the liquid obtained after steeping to spray on your plants, effectively eliminating unwanted pests.

Using Tobacco Leaves and Stems
The leaves and stems of the tobacco plant are effective against a variety of pests, including borers, leaf rollers, stink bugs, mealybugs, spider mites, and more. Simply take 1kg of dried tobacco leaves and stems and soak them in 20-40 liters of water for a day. Then, grind this mixture and spray it onto your plants to keep pests at bay. Adjust the amount of tobacco used depending on the size of your garden.
Syringa Tree Water
The Syringa tree, also known as the lilac tree, contains oil that repels insects and other pests. Its leaves have a bitter taste and also act as a natural pesticide. Take 15ml of lilac oil (or grind dried lilac leaves and berries) and mix it with a teaspoon of dish soap and 1.9ml of water. Pour the mixture into a spray bottle and apply it wherever needed.
Tomato Leaves
Tomato leaves contain alkaloids, which are natural insecticides. Take two bowls of tomato leaves and crush them, then soak them in two cups of water overnight. In the morning, strain the liquid and add another two cups of water to dilute the solution. Spray this mixture on your plants to deter insects and other pests.
Creating these natural pest control solutions is simple, and the ingredients are easily accessible. Using these eco-friendly methods ensures the safety of your produce and the environment, free from harmful chemicals. If you’re growing vegetables or fruit trees on a small scale in your backyard or on your rooftop, consider adopting these pest control methods to ensure a healthy and chemical-free harvest.
