In this guide, I will be giving you organic tips on how to make homemade aphid killers.

For those with vegetable gardens, you would have come across aphids. They are tiny insect pests, also called “plant lice” and they feast on garden plants by latching on to the leaves or base and suck up their nutrients.

This feeding habit is bad for your plants, as it causes them to turn yellow, curl at the leaves, or wither as a whole.

About Aphids

Aphids repopulate very fast, so if you don’t notice the problem on time, a lot of plants would have been damaged already. They can also spread viruses from one plant to the other.

Luckily, there are steps you can take to fight aphids, and you do not need a professional pest control service to achieve this. You can cook up several natural remedies right in the comfort of your home.

You may wonder, won’t chemical sprays work faster? Well, they can, but you have to weigh both options before you proceed to disinfest.

Homemade Aphid Killers Vs  Chemical Aphid Killers

The major reason people plant fruit-bearing trees is to eat them of course. For this reason, a chemical aphid killer may not be your best option, as the spray may harm or kill your plants.

Other home gardeners plant for the sake of having the sweet-smelling fragrance of their flowers flow into their homes. If you use a chemical aphid killer on your garden flowers, the harmful chemicals will also be transferred into your home.

Organic homemade aphid killer on the other hand poses no threat to you or your succulents. There are several organic combinations you can use to kill aphids.

Below are a few recipes.

A combination of liquid soap and water can do a lot of damage to aphids. It is simple to make and anyone can do it.

All you will need is a few tablespoons of mild liquid soap and about a pint of water.

The best way to apply the soap and water mixture is to spray some of it on the sponge and gently wipe it across the leaves of the affected plants.

As you wipe, be sure to check under the leaves, just in case aphid eggs and larvae are finding there. Wipe those off too.

Essential Oils

As far as aromatherapy goes, essential oils have always been constantly used. But that isn’t all that it’s good for, it can also be combined in several ways to get rid of aphids and other insect pests.

Using a mixture of thyme, peppermint, cloves, and rosemary oils, you can whip up a highly potent pesticide that will annihilate aphids in an instant. The great thing about this combination is that it can also repel them and keep them from coming back.

Garlic Oil Spray

Garlic is one of the most potent organic foods you can use to kill and repel pretty much any insect pest. It contains sulfur that these pests find extremely toxic and they cannot stand being around it.
