Herbal Pest Control Remedies That Actually Work

Not all insects that go to gardens and farms are bad for your plants. Even in homes, applying chemical pesticides might bring more harm than safety. Switching to herbal pest control remedies does not only save you money, but they are, in fact, more effective than chemicals. We will share with you the best homemade solutions to control pests in your homes, backyards, and farms.

Herbal Pest Control Strategies


1. Sizzle them with Soap Spray

One significant way to get rid of aphids, beetles, whiteflies, and insects is a homemade soap spray. This technique is proven to be highly effective in controlling tiny insects. When choosing this option, prepare 1 ½ teaspoon of a moderately active liquid soap and mix it with 1 quart of water.

Start spraying the herb-scented soap mixture over the infected parts of the plants. It is recommended to use this homemade remedy during evenings and early mornings. Applying it in the hottest part of the day such as noon is not advisable.

2. Inexpensive oil spray

We can eliminate little troublesome insects like thrips, mites, and aphids with a homemade insecticide made with mixed vegetable oil and mild herbal soap. When preparing this oil-based insecticide, ready a cup of vegetable oil, pour one tablespoon of soap, put in a container, and shake well. Upon using, add two teaspoons of the solution to 1 quart of water (cover and shake).

The oil spray insecticide works in the same manner as the soap spray solution above. You have to apply the spray directly to parts of the plant affected by the devastating insects. The oil in the mixture serves as a suffocating material to block the respiration of insects and eventually get rid of them.

3. Garlic insecticide spray

We all know that garlic has a pungent aroma. This sharp scent is the key reason why garlic is useful to shy away insects. Garlic is one of those commonly found herbs in kitchens that can knock out and eliminate tenacious insects. To make this spray, take two bulbs of garlic, add water, and puree them using a blender or food processor. Overnight, let the mixture sit and filter the garlic particles out. Put the garlic water in a spray bottle.

If possible, try adding ½ cup of vegetable oil and one teaspoon of mild liquid soap, and make it full by adding water. Once you decide to use this spray, mix 1 cup of the solution with 1 quart of water for maximum effectiveness in your garden or backyard.

4. Chili pepper spray

Do you love those spicy bits in your dishes? It may be surprising that your kitchen partner can get rid of annoying insects that roam around your garden. Chili pepper can be an excellent homemade natural insect repellent against a diverse set of pests. To create one, you need chili pepper or pureed fresh Chili pepper from the market. When you have powder as the vital ingredient, put one tablespoon of the chili powder or puree, several drops of mild soap, and 1 quart of water in a container.

On the other hand, when you have fresh Chili Pepper, puree or blend ½ cup of chopped pepper with 1 cup of water. Boil the mixture as you add another cup of water. Let the mixture cool after a few minutes. Strain the chili material out of the liquid solution and add liquid soap drops into it. A hint of caution, chili peppers are also potent to humans. Be sure to wear prescribed protective equipment when handling them to prevent contact with the eyes, nose, or mouth.

5. Tomato leaf as natural insecticide

Tomato leaves surprisingly showed insecticidal properties. Being part of the nightshade family, tomato plants contain alkaloids that can repel insects. These substances inside tomato leaves are called “tomatine” that are most effective when controlling aphids and other insects. Start making tomato leaf spray by chopping 2 cups worth of tomato leaves.

A simple suggestion: when picking the leaves, you can opt to get the bottom part of the plant. You can puree the leaves and add 1 quart of water. Let them sit overnight and filter afterward. This mixture is strong enough to protect your garden from the pesky insects.

Science proves that neem tree extract can disrupt growth stages among insects of different kinds. It attacks and effectively kills insects when they were in the form of eggs, larvae, or even adults which makes neem oil a powerful natural insecticide.

Neem oil does not only function as an insect-killer but also as a preventing agent against pests.

Neem oil acts as an antifeedant for insects that eat up leaves and plant parts. Since it is biodegradable, neem oil is non-toxic to pets, buts, fish, and other wildlife. You can usually find neem oil in garden stores or natural food market outlets.
