How to Get Rid of Lerps on Citrus Plant

If you are a citrus plant owner, you may have encountered a small, white, waxy insect that attaches itself to the leaves and stems of your plant. This insect is called a lerp, and it is not harmful to humans, but it can cause damage to your citrus plant. The good news is that there are several methods you can use to get rid of lerps and prevent them from coming back.

What are Lerps?

Lerps are small insects that belong to the psyllid family. They are commonly found on citrus plants such as lemons, oranges, and grapefruits. These insects feed on the sap of the plant and secrete a waxy substance that forms a protective covering over them. This covering is what gives lerps their distinctive appearance.

Why are Lerps Harmful to Citrus Plants?

Lerps are harmful to citrus plants because they suck the sap from the leaves and stems of the plant, which can weaken it over time. If left untreated, lerps can cause the leaves of your citrus plant to turn yellow and fall off prematurely. This can lead to stunted growth and a reduction in fruit production.

How to Get Rid of Lerps

1. Manual Removal

One way to get rid of lerps is by manually removing them from your citrus plant. This can be done using a soft-bristled brush or your fingers. Gently brush or scrape off the waxy covering and remove the insect underneath.

2. Horticultural Oil

Horticultural oil is an effective way to get rid of lerps on your citrus plant. This oil suffocates the insect by coating their bodies with a thin film of oil. You can purchase horticultural oil at most garden centers or online. Follow the instructions on the label for application.

3. Insecticidal Soap

Insecticidal soap is another effective way to get rid of lerps on your citrus plant. This soap works by breaking down the protective covering of the insect and killing them. You can purchase insecticidal soap at most garden centers or online. Follow the instructions on the label for application.

4. Neem Oil

Neem oil is a natural insecticide that is effective in getting rid of lerps on your citrus plant. This oil disrupts the life cycle of the insect, preventing them from reproducing. You can purchase neem oil at most garden centers or online. Follow the instructions on the label for application.

How to Prevent Lerps

Preventing lerps from infesting your citrus plant is relatively easy. Here are a few simple steps you can take to prevent an infestation:

• Keep your citrus plant healthy by providing it with adequate water and nutrients.
• Prune your citrus plant regularly to remove any dead or damaged branches.
• Inspect your plant regularly for signs of insects or disease.
• Use sticky traps to catch any insects that may be present in your garden.
