How to Get Rid of Lerps on Friendship Plant

Updated: April 10, 2022

Friendship plants (Pilea involucrata) are a popular houseplant due to their attractive foliage and ease of care. However, one problem that many plant owners face with their friendship plant is the presence of lerps. Lerps are small, scale-like insects that attach themselves to the underside of leaves, creating a sticky, honeydew-like substance that can attract other pests and cause damage to the plant. Fortunately, there are several methods you can use to get rid of lerps on your friendship plant.

Identifying Lerps

Before we begin discussing how to get rid of lerps, it’s important to know how to identify them. Lerps are small, oval-shaped insects that are usually brown or yellow in color. They create a protective covering over themselves by secreting a sticky substance, which can make them difficult to remove. The most common place to find lerps on a friendship plant is on the underside of leaves.

Method 1: Manual Removal

The first method for getting rid of lerps on your friendship plant is manual removal. This involves physically removing the lerps from the plant using a cotton swab or piece of tissue paper. To do this, simply gently rub the cotton swab or tissue paper over the affected areas, being careful not to damage the leaves or stems. Repeat this process regularly until all the lerps have been removed.

Method 2: Insecticidal Soap

Another effective method for getting rid of lerps on your friendship plant is using insecticidal soap. Insecticidal soap is a type of pesticide that is made from natural ingredients like potassium salts of fatty acids. It works by disrupting the cell membranes of insects, causing them to dehydrate and die.

To use insecticidal soap on your friendship plant, mix one tablespoon of insecticidal soap with one quart of water in a spray bottle. Spray the solution directly onto the affected areas, being sure to cover both the top and underside of leaves. Repeat this process every seven to ten days until all the lerps have been eliminated.

Method 3: Neem Oil

Neem oil is another natural pesticide that can be effective at getting rid of lerps on your friendship plant. Neem oil is made from the seeds of the neem tree and works by disrupting the hormonal systems of insects, preventing them from feeding and reproducing.

To use neem oil on your friendship plant, mix one tablespoon of neem oil with one quart of water in a spray bottle. Spray the solution directly onto the affected areas, being sure to cover both the top and underside of leaves. Repeat this process every seven to ten days until all the lerps have been eliminated.

Method 4: Horticultural Oil

Horticultural oil is a type of pesticide that is made from petroleum or vegetable oils. It works by suffocating insects, causing them to die from lack of oxygen.

To use horticultural oil on your friendship plant, mix one tablespoon of horticultural oil with one quart of water in a spray bottle. Spray the solution directly onto the affected areas, being sure to cover both the top and underside of leaves. Repeat this process every seven to ten days until all the lerps have been eliminated.
