How To Repel Aphids With A Citrusy Essential Oil They Can't Stand

If you're an avid gardener or houseplant enthusiast, then you may be familiar with just how pesky an aphid invasion can be. Aphids suck the saps from plants, and they reproduce rapidly, which turns a small inconvenience into a large one fast. On the bright side, aphids rarely lead to actual plant death. Instead, the honeydew they leave behind often attracts ants or can lead to mold development, which is why plant lovers may prefer to find ways to repel aphids from their garden. While many official sources don't recommend the use of pesticides, there is a more natural solution to help you handle garden pest control and aphid problems, and it's a citrusy essential oil you may already have on hand.

Essential oils are concentrated oils made from various parts of one plant. Orange essential oil is typically made from the rind, but it can also be derived from the leaves and the flowers. There are many ways you can use orange essential oil around your home and garden. This includes for aphid control, as there is research backing up orange essential oil's impact on aphids. One study published on Multidisciplinary Digital Publishing Institute (MDPI) shows that essential oils derived from Citrus aurantium repelled up to 88% or 100% of aphids (depending on species) in a three-hour experimental exposure window. Meanwhile, another study found that essential oils derived from Citrus sinensis show aphicidal effects — meaning that it also worked to kill aphids.

One of the best ways to use this for yourself is by creating a DIY essential oil solution for aphids that can easily be applied to your garden. To make a spray using orange essential oil, you'll want to dilute heavily with water, using only a few drops of the oil itself. When you're working with essential oils, a little can go a long way. Then, combine well and spray on your plant. Keep in mind that aphids may not be the only ones put off or even harmed by essential oil sprays, however. If you're working with a pollinator garden or similar area where you expect insects to visit, you may wish to live in harmony with the occasional aphid rather than put your entire backyard bug ecosystem at risk. You can also try repelling aphids with orange peels around your plant for a similar effect.

When using essential oils in the garden, there are just a few things to be wary of. First, these oils are potent, which means that they can also be irritating. As a result, you'll want to wear the right PPE, such as gloves, when handling essential oils and avoid direct contact with your skin. You'll also want to be sure that no curious children or pets can get their hands, paws, or mouths on these oils.
