Neem Oil Recipe#1: A Natural and Effective Insecticide for Chilli Plants 

Neem oil has long been a natural and effective insecticide for various plants, including Chilli peppers. Made from the seeds of the neem tree, this oil is known for its powerful pesticidal properties. To create your neem oil insecticide for Chilli plants, mix two to three tablespoons of neem oil with 1 gallon of water. Make sure to use pure, cold-pressed neem oil for maximum effectiveness. 

Next, add ½ teaspoon of liquid dish soap to the mixture. This will help the solution stick to the leaves and pests more effectively. Once everything is combined, generously apply it to both sides of the leaves on your chili plants. Be thorough in your application to ensure all areas are covered. The active compounds in neem oil disrupt insects’ hormonal systems and prevent them from feeding and reproducing. This makes it an excellent choice for controlling common pests like aphids, whiteflies, and spider mites that can damage Chilli plants.

If you’re looking for a natural and non-toxic way to keep pests away from Chilli plants, look no further than soap solution. This DIY insecticide is easy to make and highly effective in controlling common garden pests. The soap acts as a surfactant, which helps the solution stick to the insects’ bodies, suffocating them.

Mix a teaspoon of liquid dish soap with one liter of water to make your soap solution. Stir gently until well combined. Be sure to use mild or organic dish soap without harsh chemicals that could harm your plants. Once your mixture is ready apply directly onto the affected areas of your Chilli plants. Make sure to cover both sides of the leaves thoroughly for maximum effectiveness.

It’s important to note that this repellent may need reapplication after rain or heavy watering. 

Cayenne Pepper Spray Recipe#4: A Hot and Effective Insecticide for Chilli Plants 

The natural compound in cayenne pepper called capsaicin irritates insects, causing them to stay away from your precious Chillies. Mix one or two tablespoons of cayenne pepper powder with one quart of water to make a simple cayenne pepper spray. Add 2 to 3 drops of dish soap to help the mixture adhere to the leaves. Shake well and then strain the mixture into a spray bottle. 

Wear gloves when using this hot concoction on your Chilli plants, and avoid getting it in your eyes or mouth. Spray the solution liberally over the leaves of your plants, making sure to cover all areas where pests may hide. The strong smell and taste of cayenne pepper will deter many common garden pests, such as aphids, spider mites, and caterpillars. Reapply every week or after rain showers for maximum effectiveness. 

Pyrethrin Spray Recipe#5: A Natural Insecticide for Chilli Plants 

If you’re looking for a natural and effective insecticide to protect Chilli plants, look no further than pyrethrin spray. To make your pyrethrin spray at home, start by crushing dried chrysanthemum flowers into a fine powder. You can also purchase pyrethrins in powder form from gardening stores.

Mix one tablespoon of the powdered pyrethrins with one gallon of water and shake well. Once mixed, transfer the solution into a spray bottle or garden sprayer. When applying the pyrethrin spray to your Chilli plants, focus on targeting areas where pests are present or prone to attack. It’s always best to follow label instructions carefully and avoid spraying directly onto edible parts of your Chilli plants. 

Diatomaceous Earth Recipe#6: A Natural Insecticide for Chilli Plants 

To use diatomaceous earth as an insecticide for your chili plants, simply sprinkle it around the base of each plant and on the leaves. As soon as the bugs come into contact with this powdery substance, it will effectively damage their exoskeletons and dehydrate them, leading to their ultimate demise. Wear gloves when applying it, and avoid inhaling large dust particles. One important thing to remember about diatomaceous earth is that it works best when dry. So, if you expect rain or watering your plants soon after application, you may need to reapply the powder. 

Bacillus Thuringiensis Recipe#7: A Bacterial Insecticide for Chilli Plants 

Purchase a product containing live bacteria to make your own Bacillus Thuringiensis spray. Follow the instructions to mix it with water in the recommended ratio. Then, use a sprayer to apply the solution evenly onto your Chilli plants. The beauty of using Bacillus Thuringiensis is that it only affects certain types of insects, such as caterpillars and worms. Once ingested by these pests, Bacillus Thuringiensis releases toxins that paralyze their digestive systems and ultimately lead to their death.

This natural solution is effective against many pests, including aphids and scale insects.

To make your horticultural oil spray for Chilli plants, you’ll need two tablespoons of horticultural oil and 1 gallon of water. Mix the ingredients thoroughly and apply the solution to the leaves and stems of your Chilli plants.

Insecticidal Soap Recipe#9: A Gentle Insecticide for Chilli Plants 

Mix one to two tablespoons of liquid dish soap with one quart of water. Stir it well until the soap is completely dissolved. When applying the insecticidal soap to your Chilli plants, thoroughly cover both sides of the leaves. This will help smother any existing insects and deter new ones from settling in. Remember that this recipe works best on soft-bodied insects like aphids or spider mites. 

Beer Traps: A Natural Insecticide for Chilli Plants 

These traps attract slugs, snails, and other garden pests with the smell of beer. Once they crawl into the trap, they drown in the liquid. To make a beer trap for your Chilli plants, simply bury a shallow container in the soil near your plants and fill it halfway with beer. The pests will be drawn to the sweet scent of the drink and fall into their doom. One important thing to note is that you should use cheap beer for this purpose, as expensive craft beers may not have the same effect on insects.

By strategically planting certain companion plants near your chilies, you can create an environment that deters pests and promotes healthy growth. One popular companion plant for chili peppers is Marigold. The strong scent of marigolds acts as a natural insect repellent, keeping aphids, nematodes, and other harmful bugs away from your chili plants.

Plus, the bright flowers add a pop of color to your garden. Another great companion plant for chilies is Basil. It enhances the flavor of your dishes when paired with fresh chili peppers, and Basil also helps repel mosquitoes and flies. It’s a win-win situation.
