How to Get Rid of Lerps on Green Bean Plant

If you’re growing green beans, you might have encountered a problem with small, white, waxy insects called lerps. They attach themselves to the underside of leaves and feed on sap, causing damage to the plant. Here are some steps you can take to get rid of lerps on your green bean plant.

Identify the Problem

Before taking action, it’s important to identify if your green bean plant is affected by lerps. Look for small, white, waxy bumps on the underside of leaves. If you see these bumps, gently touch them to see if they come off easily. If they do, it’s likely that you have a lerp infestation.

Remove Lerps Manually

One way to get rid of lerps is to remove them manually. This method is best for smaller infestations. You can use a soft-bristled brush or a cotton swab dipped in rubbing alcohol to gently scrub away the lerps. Be sure to dispose of any lerps you remove.

Use Insecticidal Soap

Insecticidal soap is an effective and safe way to get rid of lerps on your green bean plant. It works by breaking down the protective coating of the insect, causing it to dehydrate and die. You can buy insecticidal soap at most garden centers or make your own by mixing 2 teaspoons of mild dish soap with 1 quart of water.

To apply insecticidal soap, mix the solution according to the instructions and spray it directly onto the affected leaves. Be sure to cover both sides of the leaves thoroughly. Repeat this process every few days until all of the lerps are gone.

Use Neem Oil

Neem oil is another effective and natural way to get rid of lerps on your green bean plant. It works by interfering with the insect’s hormonal system, causing it to stop feeding and eventually die. You can buy neem oil at most garden centers.

To use neem oil, mix the solution according to the instructions and spray it directly onto the affected leaves. Be sure to cover both sides of the leaves thoroughly. Repeat this process every few days until all of the lerps are gone.

Prune Affected Leaves

If your green bean plant has a severe lerp infestation, you may need to prune affected leaves. This will help to stop the spread of the infestation and allow the plant to focus its energy on healthy leaves. Use clean pruning shears to remove any leaves that are heavily infested with lerps.
