How to Get Rid of Aphids on Creeping Jenny Plant

Updated: April 28, 2022

Creeping Jenny plant, also known as Lysimachia nummularia, is a popular ground cover that is commonly used in landscaping. This plant is known for its bright yellow-green leaves that create a beautiful carpet-like effect. However, like other plants, creeping Jenny can be attacked by aphids, which can cause significant damage to the plant. In this article, we will discuss how to get rid of aphids on creeping Jenny plant.

Understanding Aphids

Aphids are small, soft-bodied insects that are typically found on the undersides of leaves and stems. These insects feed on plants by piercing their skin and sucking the sap out of them. Aphids can reproduce rapidly, and a single aphid can produce up to 80 offspring in just one week.

Signs of Aphid Infestation

The first sign of an aphid infestation is the presence of sticky or shiny leaves. This is caused by the honeydew, a substance that aphids excrete as they feed on the plant. You may also notice that the leaves are curling or yellowing. In severe cases, you may see black sooty mold growing on the honeydew.

How to Get Rid of Aphids on Creeping Jenny Plant

1. Blast Them Off

One way to get rid of aphids is to blast them off using a strong stream of water. This method works best for small infestations and can be done using a garden hose. Spray the affected area with water, making sure to hit both the upper and undersides of the leaves.

2. Use Insecticidal Soap

Insecticidal soap is a natural and effective way to get rid of aphids. It works by suffocating the insects and disrupting their cell membranes. Insecticidal soap is safe for plants, humans, and pets, and can be found at most garden centers. To use, spray the affected area with insecticidal soap, making sure to cover both the upper and undersides of the leaves.

3. Apply Neem Oil

Another natural way to get rid of aphids is to apply neem oil. Neem oil is derived from the neem tree and contains compounds that repel and kill insects. To use, mix one tablespoon of neem oil with one gallon of water and spray the affected area. Repeat this process every seven to ten days until the infestation is under control.

Preventing Aphid Infestations

The best way to deal with aphids is to prevent them from attacking your plants in the first place. Here are some tips for preventing aphid infestations:

  • Practice good gardening hygiene: Remove any plant debris or dead leaves from around your creeping Jenny plant. Aphids are attracted to decaying organic matter, so keeping your garden clean can help prevent infestations.

  • Encourage natural predators: Ladybugs, lacewings, and other beneficial insects are natural predators of aphids. Encouraging these insects in your garden can help keep aphid populations under control.

  • Avoid over-fertilizing: Aphids are attracted to plants that are high in nitrogen. Avoid over-fertilizing your creeping Jenny plant, as this can make it more susceptible to aphid infestations.


Are aphids harmful to humans?

No, aphids are not harmful to humans.

Can I use chemical insecticides to get rid of aphids?

While chemical insecticides can be effective against aphids, they can also harm beneficial insects and pollinators. We recommend using natural methods whenever possible.

Can I eat creeping Jenny plant if it has aphids?

We do not recommend eating any plant that has been infested with aphids. The honeydew that aphids produce can contain harmful bacteria and viruses.
