English ivy is a beautiful and low-maintenance plant that can add a touch of greenery to any indoor or outdoor space. However, one issue that many English ivy growers face is the presence of lerps. These tiny insects can cause significant damage to the plant if left untreated. In this article, we will discuss what lerps are, how to identify them, and most importantly, how to get rid of them.

What Are Lerps?

Lerps are tiny insects that look like small brown or white bumps on the leaves and stems of plants. They are actually the protective covering of the psyllid insect, which feeds on the sap of the plant. Lerps are most commonly found on English ivy plants, but they can also infest other types of plants.

When lerps feed on a plant, they suck out its sap, which can weaken and damage the plant. If left untreated, a lerp infestation can cause the plant’s leaves to turn yellow and eventually fall off.

How to Identify Lerps?

Identifying lerps is relatively easy. They look like tiny bumps that are either brown or white in color. You can find them on both the leaves and stems of your English ivy plant. If you see small groups of bumps on your plant’s surface, you likely have a lerp infestation.

Another sign of lerp infestation is sticky honeydew residue on leaves and stems. This sticky substance is actually excrement produced by the psyllid insect as it feeds on the plant’s sap.

How to Get Rid of Lerps?

Getting rid of lerps requires a multi-step approach that includes both physical removal and chemical treatment. Here are some steps you can take to get rid of lerps on your English ivy plant:

Step 1: Prune Infested Parts

The first step is to prune any infested leaves, stems, or branches. This will remove the majority of lerps from your plant and prevent them from spreading to healthy parts of the plant.

Step 2: Use a Hose

After pruning, use a hose to spray your English ivy plant thoroughly. The force of the water will dislodge any remaining lerps and honeydew residue.

Step 3: Apply Insecticidal Soap

Insecticidal soap is an effective chemical treatment for lerps on English ivy plants. To use, mix the soap with water according to the instructions on the label, and then spray it directly onto the affected areas of your plant. Be sure to cover both the tops and bottoms of your plant’s leaves.

Repeat this process every two weeks until the lerp infestation is under control.

Frequently Asked Questions (FAQs)

Can I use neem oil to get rid of lerps?

Yes, neem oil is an effective natural treatment for lerp infestations on English ivy plants. Mix the neem oil with water according to the instructions on the label and then spray it directly onto the affected areas of your plant.

In conclusion, lerp infestations can be a nuisance for English ivy growers. However, with proper identification and treatment methods, you can get rid of them and protect your plant. Remember to prune infested parts, use a hose to dislodge remaining lerps, and apply insecticidal soap or neem oil to prevent them from coming back.
