A fungus called soot mold grows on honeydew and blocks the amount of light that enters your plant (but is otherwise harmless). Aphids are small, soft-bodied insects with long, slender mouthpieces that they use to pierce stems, leaves, and other delicate plant parts and suck out liquids. For one batch, mix 1 head of garlic, 1 small onion and 1 teaspoon of cayenne pepper in a food processor or blender and work into a paste. Two more types of homemade sprays can also fight aphids.

Aphids have soft pear-shaped bodies with long legs and antennae and can be green, yellow, brown, red, or black depending on the species and plant they feed on.

How to get rid of aphids on plants?

One of the reasons aphids are so prevalent, especially in areas like California with moderate temperatures, is that they don't really need to mate before they get young. Often the wingless aphids remain hidden on the underside of the leaves, but it is very easy to detect a large infestation as they accumulate in large quantities. In addition, you can grow plants on the opposite side of your property that attract aphids such as marigold and nasturtium. You can withdraw aphids from the affected area. Of all the natural remedies to get rid of aphids quickly and effectively (not to mention the inexpensive ones), a simple, powerful jet of water is one of the best and easiest ways to fight these pests.

Does vinegar kill aphids?

You can make a spray of vinegar and water and spray the aphids, causing them to burn and die. Although hydrogen peroxide isn't as effective on aphids as its above-ground relatives because it's difficult to reach it, it can act as an insecticide and kill the aphid population in your plants' soil. Although you can use other natural pesticides to control aphids like neem oil spray to treat your plants, having vinegar in your kitchen, a great homemade aphid spray, is enough to remedy the problem. It is rare for people to be allergic to vinegar or get irritated by it, which is great as you have one less thing to worry about.
