6 Natural Repellents and Predators for Plant Pests
What are Natural Repellents?
A natural repellent is a substance that is used to deter pests, such as insects or animals, from a specific area or object. Natural repellents are typically derived from plants or other natural sources and are often used as an alternative to chemical pesticides. They may be applied in various forms, such as sprays, ointments, or essential oils, and are generally considered to be safer and more environmentally friendly than chemical pesticides.
The Best Natural Pest Repellents
There are many natural pest repellents that can be used to help control pests in gardens and on plants. Some of the most effective natural pest repellents include:
Neem oil: This oil, which is derived from the neem tree, is a natural insecticide that can be used to control a wide range of pests, including aphids, mites, and whiteflies.
Garlic spray: Garlic has natural insect-repelling properties, and a homemade garlic spray can be effective at controlling a variety of pests, including aphids and Japanese beetles.
Hot pepper spray: Capsaicin, the compound that gives peppers their heat, is a natural insect repellent. Mixing hot peppers with water and a few drops of dish soap can create a homemade hot pepper spray that can be effective at controlling pests like aphids and tomato hornworms.
Diatomaceous earth: This natural substance is made from the fossilized remains of tiny aquatic organisms called diatoms. When applied to plants, it can help control pests like slugs, aphids, and thrips by cutting through their exoskeletons and drying them out.
Copper tape: This tape, which is made from copper, can be effective at controlling slugs and snails when placed around the base of plants. The copper reacts with the slime produced by these pests, creating an electrical current that deters them.
Herbal repellents: Certain herbs, such as basil, catnip, and marigolds, have natural pest-repelling properties. Planting these herbs near your garden or using them in a homemade repellent spray can help control pests like aphids, whiteflies, and mosquitoes.
Almost all of these treatment methods are safe to use around pets. Its always important to keep a close eye on any pets and children when dealing with houseplants. Any ingestion should warrant a visit to the vet or doctor.
