Most Common Elderberry Plant Pests:
Identification and Treatment Guide

Elderberry plants are a popular addition to many gardens due to their beautiful blossoms and nutritious berries. However, they are also susceptible to pests that can damage the plant and reduce its yield. In this article, we will discuss some of the most common elderberry plant pests, how to identify them, and the best treatment options to keep your plants healthy.

Aphids

Aphids are small, soft-bodied insects that feed on the sap of plants. They are usually found on the undersides of leaves and can cause stunted growth, curled leaves, and yellowing foliage. The most common species of aphids that attack elderberry plants are black bean aphids, which are small and black.

Identification

Aphids are easy to spot on elderberry plants. Look for clusters of small, soft-bodied insects on the undersides of leaves. They may be black, green or brown in color.

Treatment

To control aphids, you can spray the affected plant with insecticidal soap or neem oil. You can also introduce beneficial insects such as ladybugs or lacewings to your garden. These insects feed on aphids and can help control their population.

Spider Mites

Spider mites are tiny arachnids that feed on the sap of plants. They are usually found on the undersides of leaves and can cause yellowing foliage, webbing, and premature leaf drop.

Identification

Spider mites are difficult to see with the naked eye but can be identified by the fine webbing they produce on the undersides of leaves. Infested leaves may also appear dusty or speckled.

Treatment

To control spider mites, you can spray the affected plant with a strong jet of water to knock off the mites. Alternatively, you can use insecticidal soap or neem oil. It is important to treat the plant as soon as you notice an infestation to prevent the mites from spreading.

Japanese Beetles

Japanese beetles are a common pest that can cause significant damage to elderberry plants. They feed on the leaves, flowers, and fruit of the plant, leaving behind skeletonized leaves and damaged fruit.

Identification

Japanese beetles are metallic green with copper-colored wings. They are about ½ inch long and have six legs.

Treatment

To control Japanese beetles, you can handpick them off the plant and drop them into a bucket of soapy water. You can also use a pheromone trap to attract and capture the beetles. Insecticidal sprays are also effective, but be sure to follow the instructions carefully to avoid damaging beneficial insects.

Elderberry Borer

The elderberry borer is a type of beetle that lays its eggs on the bark of elderberry plants. The larvae then bore into the stem of the plant, causing girdling and eventually killing the plant.

Identification

The elderberry borer is a small black beetle with white stripes on its wings. The larvae are white with brown heads and can grow up to ¾ inch long.

Treatment

To control elderberry borers, you can prune and destroy any infested stems or branches. You can also apply insecticide to the bark of the plant to kill the larvae before they burrow into the stem.
