How to Get Rid of Lerps on Foxtail Plant

Updated: April 12, 2022

If you have a foxtail plant in your garden, you may have noticed small, white, waxy bumps on the leaves and stems. These bumps are called lerps and are caused by a type of insect called a psyllid. While lerps do not usually harm the plant, they can be unsightly and attract other pests. Here are some methods for getting rid of lerps on your foxtail plant.

Method 1: Physical Removal

One way to get rid of lerps is by physically removing them from the plant. You can use a soft-bristled brush or your fingers to gently scrape the lerps off the leaves and stems. Be careful not to damage the plant while doing so.

Method 2: Insecticidal Soap

Insecticidal soap is a safe and effective way to get rid of lerps on your foxtail plant. Look for a soap that is specifically labeled for use on plants and follow the instructions carefully. In general, you will need to spray the soap directly onto the lerps and surrounding foliage, making sure to cover all surfaces thoroughly.

Method 3: Neem Oil

Neem oil is another natural remedy for getting rid of lerps on foxtail plants. It works by disrupting the insect’s life cycle, preventing it from reproducing. Mix neem oil with water according to the instructions on the label and spray it onto the affected areas of your plant.

Method 4: Biological Control

Biological control involves using natural predators or parasites to control pest populations. In the case of lerps on foxtail plants, one option is to introduce parasitic wasps that feed on psyllids. You can purchase these wasps online or from a garden center.

Method 5: Prevention

Preventing lerps from appearing on your foxtail plant is the best way to avoid having to deal with them in the first place. One way to do this is by keeping your plant healthy and well-maintained. Make sure it receives enough water and nutrients, and prune any damaged or diseased branches.
