Do Aphids Hate Garlic? (Repelling these Pests)

Yes, aphids do hate garlic! Garlic is a natural repellent for aphids and can be used as an effective organic pest control method in your garden. In this article, we will explore why aphids dislike garlic, how to use garlic as a deterrent, and other natural remedies to keep aphids away from your plants.

Why Do Aphids Hate Garlic?

Aphids are small sap-sucking insects that can cause significant damage to plants by feeding on their sap. Garlic contains sulfur compounds, such as allicin, which give it its pungent smell and taste. These compounds act as a natural deterrent for aphids and other pests.

When aphids come into contact with garlic, they are repelled by its strong odor. The sulfur compounds in garlic can also disrupt the aphids’ feeding and reproductive processes, making it difficult for them to survive and reproduce.

Using Garlic as an Aphid Repellent

There are several ways you can use garlic to repel aphids from your plants:

1. Garlic Spray

To make a garlic spray, follow these steps:

  1. Crush several cloves of garlic and place them in a container.
  2. Add water to the container and let it sit overnight.
  3. Strain the garlic-infused water into a spray bottle.
  4. Spray the mixture onto the affected plants, focusing on the undersides of leaves where aphids tend to hide.

Repeat this process every few days or after rainfall to maintain the repellent effect.

2. Garlic Barrier

You can create a garlic barrier around your plants to prevent aphids from reaching them. Here’s how:

  1. Peel and crush several cloves of garlic.
  2. Spread the crushed garlic around the base of your plants, forming a protective circle.
  3. Alternatively, you can bury the crushed garlic cloves in the soil around your plants.

Remember to refresh the garlic barrier every few weeks or after heavy rainfall to ensure its effectiveness.

Other Natural Remedies for Aphid Control

In addition to garlic, there are other natural remedies you can use to control aphids:

1. Neem Oil

Neem oil is derived from the seeds of the neem tree and acts as a natural insecticide. Dilute neem oil with water according to the instructions on the product and spray it onto your plants to repel aphids.

2. Ladybugs

Ladybugs are natural predators of aphids and can help keep their population in check. You can attract ladybugs to your garden by planting flowers such as daisies, marigolds, and yarrow.

3. Soap Solution

Mix a few drops of mild liquid soap with water and spray it onto your plants. The soap solution will suffocate aphids and prevent them from feeding on your plants.


In conclusion, garlic is an effective natural repellent for aphids. Its strong odor and sulfur compounds make it unappealing for these sap-sucking insects. By using garlic spray or creating a garlic barrier, you can protect your plants from aphid infestations. Additionally, other natural remedies like neem oil, ladybugs, and soap solutions can also aid in controlling aphids in your garden. Embracing these organic pest control methods will help you maintain a healthy and thriving garden without the need for harmful chemicals.
