5 Effective Ways to Keep Aphids Out of Your Garden

How to Keep Aphids Out of Your Garden

If you’re a gardener, then you know that one of the most annoying pests to deal with is the aphid. These small insects can quickly take over your plants and cause serious damage if left untreated.

Fortunately, there are several things you can do to keep aphids out of your garden. In this article, we’ll cover the reasons why aphids are in your garden and how to keep them out.

Why Are Aphids in Your Garden? Aphids are attracted to food in your garden.

They like to feed on legumes, mustard plants, plants in the Solanaceae family, cucurbits, spinach, lettuce, corn, carrots, and stone fruits. If you have any of these plants in your garden, then you’re at risk for an aphid infestation.

One of the reasons aphids are so harmful is that they reproduce quickly. In the spring and fall, aphids lay eggs and migrate to new plants.

If left untreated, an aphid infestation can spread rapidly. Some of the most common aphids found in gardens are Mealy plum aphids and rosy apple aphids.

Ants can also be a factor in an aphid infestation. Ants are known to protect aphids from their natural enemies, such as parasitoid wasps and lady beetles.

Ants are attracted to honeydew, a sweet substance produced by aphids. If you have ants in your garden, then you may be dealing with an aphid problem.

Another factor in an aphid infestation is the use of high-nitrogen fertilizers. Aphids are attracted to the nitrogen content in sap and amino acids.

If you’re using a high-nitrogen fertilizer, then you may be attracting aphids to your garden. Finally, the use of pesticides and insecticides can eliminate natural predators of aphids.

Lady beetles, parasitic wasps, and spiders are all natural predators of aphids. If you’re using pesticides or insecticides in your garden, then you may be inadvertently getting rid of these important predators.

How to Keep Aphids Out of Your Garden

Now that we know why aphids are in your garden, let’s look at how to keep them out.

Inspect Plants Often and Early

One of the best ways to keep aphids out of your garden is to inspect your plants often and early. Look for signs of aphids, such as leaf curling and yellowing leaves.

You may even be able to spot aphid eggs on your plants. The sooner you can identify an aphid infestation, the easier it will be to control.

Use Scents to Repel Aphids

Another way to keep aphids out of your garden is to use scents that repel them. Peppermint oil is known to repel aphids, as are other strong-smelling oils like garlic and onion.

You can make a spray by mixing the oil with water and spraying it on your plants. Alternatively, you can plant herbs like mint and garlic around your garden to naturally repel aphids.

Manage Ants to Keep Aphids Out

If you have ants in your garden, then you’ll need to manage them to keep aphids out. One way to do this is to spray peppermint oil around your plants.

Ants are repelled by the scent of peppermint. You can also try setting up ant bait stations to lure the ants away from your plants.

Encourage Natural Aphid Predators

Finally, one of the best ways to keep aphids out of your garden is to encourage natural aphid predators. Ladybugs are especially effective at controlling aphids, as are lacewings, parasitic wasps, and spiders.

You can encourage these predators by planting perennial flowers like coneflowers and yarrow, which attract beneficial insects. You can also set up a ladybug house in your garden to provide a home for these helpful insects.


Aphids can be a serious problem for gardeners, but with a little knowledge and effort, you can keep them out of your garden. Remember to inspect your plants often and early, use scents to repel aphids, manage ants to keep aphids out, and encourage natural aphid predators.

With these measures in place, you can have a healthy and thriving garden, free from the pests that want to destroy it. In conclusion, keeping aphids out of your garden is crucial to maintaining healthy plants.

By understanding the reasons why aphids are attracted to your garden, you can take steps to prevent infestations. Inspecting your plants often, using scents that repel aphids, managing ants, and encouraging natural predators are all effective ways to keep aphids at bay.

By implementing these strategies, you can enjoy a flourishing garden free from the damage caused by these tiny pests. Remember, taking preventative measures early on is the key to a successful and thriving garden.
