Aphids are part of the most challenging tasks for gardeners to deal with predatory insects and other pests. It’s even harder when they are difficult to spot. The most prevalent garden pest, spider mites, (Tetranychus urticae), are as small as a pinhead, so they are hard to identify. These tick-like insects are instead classified as insects due to their eight legs. Many types of spider mites are found, usually in colors of red, green, yellow, or brown, with the most common two-spotted spider mite and red spider mite.
Whenever you have a vegetable garden, you might even encounter aphids. These small insects are termed plant lice. They feed off the leaves or base of the plant and suck out the nutrients, causing the plant to wither, yellow, and curl. By the time you discover the problem, aphid populations have grown so rapidly that they have already infested your garden and infected your rose bushes and plants with lethal viruses. This aphid can be fought off with a homemade aphid spray, but the question is how to make one yourself. Using liquid dish soap and a few simple instructions, you can keep these aphids out of your roses.
If you prefer not to use harmful chemicals in your garden, there are several alternative methods to control aphids. Aphids have several natural enemies, including other insects, larvae, and birds, and move fairly slowly, making them easy to remove by hand or target with sprays. Aphids multiply rapidly, so some methods will need to be combined along with repeated attempts to control them completely. Be patient with your efforts; you may not see results for quite some time.
Ways of Controlling Aphids Using Natural And Organic Sprays
#1. Using Soap and water
Spray aphids away by spraying with water from a garden hose. This is the most effective method in early spring after an infestation has established itself. You may not want to use it for younger or more delicate plants, but it is useful on plants that require a higher water pressure.
Another easiest way to make homemade aphid spray is to combine a few tablespoons of pure liquid soap with a few cups of water. Please do not use detergents or products with degreasers or moisturizers.) Just spray with a spray bottle directly on the aphids and the affected parts of the plants, making sure to soak the undersides of leaves where eggs and larvae like to hide. If you purchase ready-to-use insecticidal soap online or at your local nursery, it is easy to use and also comes in a variety of scents or colors. The soap dissolves the protective outer layer of aphids and other soft-bodied insects, killing them eventually.
#2. By Hand-picking
Put on garden gloves so you can knock them off stems, leaves, flower buds, or wherever they are, and place them in a bucket of soapy water to kill them. Cut off any affected areas and drop them into the bucket.
#3. Using Neem Oil
Among other insects, neem oil prevents aphids, cabbage worms, ants, and various types of caterpillars from invasion. However, it can also repel beneficial insects, so use caution when and where they are present. Spray the affected areas with neem oil, or mix the oil into the water to dilute. Neem oil is also effective in controlling different types of fungus.
Pure, organic Neem oil helps control the growth of fungi, molds, and insects that attack your plants. Mix it with a few drops of dish soap and five cups of water.
#4. Using Neem Oil Based Aphid Spray
After dilution, use a garden hose sprayer to mist your garden early in the morning with the mixture. Neem oil is not harmful to beneficial insects but helps to repel aphids, mosquitoes, and other pests.
Many people use essential oils in the home and gardens nowadays, including pest control. Thyme, peppermint, and clove essential oils combine to form a potent combination that kills aphids and repels them. If your cat routinely enters your garden, peppermint oil is one of the essential oils that is known to be toxic to cats. On the other hand, cats dislike the scent of rosemary, leading to its use as a deterrent to digging.
Castile soap is a straightforward, all-natural, vegetable-based liquid soap from olive and mineral oil as the main ingredient. What makes Castile soap a good natural aphid repellent is its efficacy with vinegar and water. A vinegar spray is lethal to all insect life, whether you are dealing with Japanese species of aphids or good bugs you need in your garden. Sprinkle vinegar lightly over the tops and bottoms of the leaves with a spray bottle.
#6. Using Essential Oils
Mix 4 to 5 drops of essential oils into the water and spray on affected plants to target adult aphids and larvae as well as eggs– peppermint, clove, rosemary, and thyme are recommended.
You can control aphids naturally by taking advantage of their weaknesses and making a few changes in the way you manage your garden. Natural methods of soil treatment usually work best, but they can also be less costly. It is best to keep aphids in check by having a number of natural enemies, and these insects are the best way to control aphids. This is the best way to control aphids organically. As a natural way of killing aphids, introduce beneficial insects, such as lacewings and ladybugs, to your garden. Planting mint, fennel, dill, yarrow, and dandelions near your crops will help attract these insects. Pesticides have a greater probability of killing predatory insects than aphids, so the insect population typically increases after spraying. Taking natural steps to kill aphids preserves the insects’ natural enemies while creating a hostile environment for them.
