Natural Insect Repellents for Leaf-Eating Insects

Answer

When you use pesticides that contain powerful chemicals to ward off leaf-eating predators, you run the risk of harming beneficial insects like honeybees and other insects that are useful to the plants in your yard. There is a possibility that certain pests might become immune to insecticides. Products that are natural and organic that are sold in garden shops might be an alternate method that is beneficial in warding off pests and protecting your plants. These goods are safe for the environment because they contain negligible amounts, if any, of toxic substances.

Neem Products

Neem oil and soap are two examples of a common kind of insect repellent that are both low toxic and biodegradable. This type of repellent is used all over the world to ward off over 200 different kinds of insects. The oil is extracted from a tree that is native to tropical regions (Azadiracta indica). Sprays made of neem are used by gardeners to treat the leaves. The fluid interferes with the hormone functioning of the insects and also works as an anti-feedant, stopping them from feeding. Products made from neem also have the ability to prevent insects from laying eggs.

Garlic, Onions and Hot Pepper

Insects and other pests that eat leaves may be effectively repelled by using products that you already have in your cupboard. Garlic, onions, and chilli peppers are three ingredients that may be used at home to repel a variety of eating insects, such as flea beetles, caterpillars, cabbageworms, hornworms, and aphids. Combine one chopped onion, one dried hot pepper, six cloves of garlic, one gallon of boiling water, and one tablespoon of trisodium phosphate (TSP) detergent in a blender. Blend until smooth. After allowing the solution to rest for a day, use a spray bottle to administer it to the plants.

Insecticidal Soaps

Insecticidal soap spray solutions include fatty acids that inhibit and control infestations of soft-bodied pests that eat leaves, such as thrips, scales, aphids, mites, and mealybugs. Destroying the cell membranes of the pests and causing them to become dehydrated and unable to breathe is the result of the soap solution’s ability to dissolve the bugs’ outer coating. Beetles are resistant to the insecticidal properties of soaps. Soap that kills insects may be purchased at garden supply stores.

Pyrethrins

Pyrethrins are a class of insecticides that are derived from chrysanthemums. These pesticides may be found in a variety of horticultural products. An extract may be obtained from the plants’ blooms, and this extract is useful for the management of a number of pests, including beetles and leafhoppers, which feed on vegetables, fruit trees, and ornamental plants. Pyrethrins have a toxic effect on insects, causing them to lose their ability to fly and destroying their neurological systems. Insects eventually become immobile and pass away. Pyrethrins are an ingredient in certain insect repellent products, and these products may also include additional natural pesticides such as insecticidal soap and neem oil.

Companion Plants

Some plants have a natural ability to ward off insects, which may be beneficial to other plants in the area since it keeps pests at away. The practise of planting two or more species in close proximity to one another is known as companion planting. This allows plants that are susceptible to pests to benefit from the plants that are resistant to those pests. For instance, marigolds have been shown to be effective in warding off other pests, such as the asparagus beetle. An informative graphic on companion plants may be found on the website of the National Sustainable Agriculture Information Service. Gardening clubs and cooperative extension agencies may also be able to supply information on companion plants well-suited to certain regions of the country.
