Most Common Creeping Jenny Plant Pests:
Identification and Treatment Guide

Creeping Jenny, also known as Lysimachia nummularia, is a popular groundcover plant that is native to Europe and Asia. It is loved for its bright green foliage and delicate yellow flowers that bloom in the summer. However, like all plants, creeping Jenny is susceptible to pests that can damage or kill it if left untreated.

In this article, we will discuss the most common pests that attack creeping Jenny plants, how to identify them, and the treatment options available.

1. Aphids

Aphids are tiny, pear-shaped insects that suck the sap from the leaves of plants. They are usually green or yellow in color and can be found in large numbers on the undersides of leaves. The presence of aphids can cause stunted growth, yellowing leaves, and distorted foliage.

Identification

To identify aphids on your creeping Jenny plant, look for clusters of small insects on the leaves and stems. You may also notice a sticky residue on the plant’s surface, which is a sign of honeydew excreted by the aphids.

Treatment

Aphids can be treated with insecticidal soap or neem oil spray. Both products are safe for use on plants and will kill the aphids without harming beneficial insects like ladybugs and lacewings.

2. Spider Mites

Spider mites are tiny arachnids that feed on the sap of plants. They are usually red or yellow in color and can be found on the undersides of leaves. The presence of spider mites can cause yellowing leaves, stunted growth, and webbing on the plant’s surface.

Identification

To identify spider mites on your creeping Jenny plant, look for tiny dots on the undersides of leaves. You may also notice webbing on the plant’s surface, which is a sign of spider mite infestation.

Treatment

Spider mites can be treated with insecticidal soap or neem oil spray. You can also use a high-pressure hose to wash them off the plant’s surface. Be sure to spray both the top and bottom of the leaves for maximum effectiveness.

3. Slugs and Snails

Slugs and snails are mollusks that feed on the leaves of plants. They are usually active at night and can cause significant damage to creeping Jenny plants if left unchecked. The presence of slugs and snails can cause irregular holes in the leaves and slime trails on the plant’s surface.

Identification

To identify slugs and snails on your creeping Jenny plant, look for slime trails on the plant’s surface. You may also notice irregular holes in the leaves, especially near the edges.

Treatment

Slugs and snails can be controlled using baits, traps, or by manually removing them from the plant’s surface. You can also create a barrier around your plants using copper tape or diatomaceous earth to prevent them from reaching your plants.
