What are aphids?

Aphids are tiny, soft-bodied insects that feed on plants by sucking out the sap. They reproduce quickly, which can result in an infestation that damages your plants.

Why use natural remedies?

Using chemical insecticides to control aphids can harm beneficial insects and pollute the environment. Natural remedies are a safer alternative that can be just as effective at deterring aphids.

Benefits of using plants as aphid repellents

If you're looking for natural solutions to repel aphids, consider planting these 10 plants in your garden:

10. Lavender

Lavender is a beautiful and aromatic plant that repels aphids while attracting beneficial insects. The strong scent of lavender makes it an effective repellant, and its purple flowers serve as a natural insecticide.
