How to Get Rid of Lerps on Fiddle Fig Plant

Fiddle fig plants, also known as Ficus lyrata, are popular houseplants for their large, violin-shaped leaves that add a touch of elegance to any indoor space. However, these plants are prone to an infestation of tiny insects called lerps, which can cause damage to the leaves and affect the plant’s overall health. In this article, we will discuss what lerps are, how they affect fiddle fig plants, and most importantly, how to get rid of them.

What are Lerps?

Lerps are small insects that belong to the family Psyllidae. They are commonly found on ficus plants, including fiddle figs. Lerps are tiny and difficult to spot with the naked eye. They are about 1/16th of an inch long and have a brown or gray color.

Lerps feed on the sap of the plant and excrete a sugary substance called honeydew. This sticky substance can attract other pests like ants and promote the growth of sooty mold, which can further damage the plant.

How do Lerps Affect Fiddle Fig Plants?

Lerps can cause significant damage to fiddle fig plants if left untreated. They feed on the sap of the plant, causing the leaves to turn yellow and drop prematurely. In severe cases, lerps can cause stunted growth and even kill the plant.

Apart from direct damage, lerps also attract other pests like ants, which can further harm the plant. The honeydew produced by lerps can promote the growth of sooty mold, a fungal disease that grows on the surface of leaves and stems.

How to Get Rid of Lerps on Fiddle Fig Plant?

Getting rid of lerps requires a combination of manual removal and insecticidal treatment. Here are some steps you can take to get rid of lerps on your fiddle fig plant:

Step 1: Identify Infested Leaves

The first step is to identify which leaves are infested with lerps. Look for small bumps or blister-like structures on the underside of leaves. These bumps are actually the protective coverings that lerps create to shield themselves from predators and insecticides.

Step 2: Remove Infested Leaves

Use a pair of scissors or pruning shears to remove the infested leaves. Be careful not to damage the healthy leaves or stems. Dispose of the infested leaves immediately to prevent further infestation.

Step 3: Spray with Insecticidal Soap

Insecticidal soap is an effective treatment for lerps. It works by suffocating the insects and disrupting their feeding activity. Mix the insecticidal soap according to the manufacturer’s instructions and spray it on the remaining leaves and stems. Be sure to cover both sides of the leaves, as lerps often hide on the underside.

Repeat the application every 5-7 days until all the lerps are eliminated. Be sure to follow the safety instructions on the product label and avoid spraying in direct sunlight or on windy days.

Step 4: Monitor for Re-infestation

After treatment, monitor your fiddle fig plant regularly for any signs of re-infestation. Check the underside of leaves for any bumps or blisters and remove them immediately if detected. You can also use yellow sticky traps to catch any adult lerps that may have survived.

FAQ

Can I prevent lerps from infesting my fiddle fig plant?

Yes, you can take several preventive measures to avoid lerps infestation. These include:

• Inspecting new plants before bringing them indoors
• Quarantining new plants for at least two weeks before introducing them to your existing plants
• Keeping your plants clean by wiping the leaves with a damp cloth regularly
• Avoiding over-fertilization, as lerps are attracted to high nitrogen levels in the soil

Can I use neem oil to treat lerps infestation?

Yes, neem oil is another effective treatment for lerps. Mix neem oil with water according to the manufacturer’s instructions and spray it on the infested leaves and stems. Repeat the application every 5-7 days until all the lerps are eliminated. However, be sure to use pure neem oil and avoid using products that contain other additives.

Can I use chemical insecticides to treat lerps infestation?

Yes, chemical insecticides can also be used to treat lerps infestation. However, they should be used as a last resort and only when other treatments have failed. Choose a product that specifically targets psyllids and follow the safety instructions on the label carefully.

Conclusion

Lerps can be a nuisance for fiddle fig plant owners, but with proper treatment and preventive measures, they can be eliminated. Remember to inspect your plants regularly and take action at the first sign of infestation. With patience and perseverance, you can keep your fiddle fig plant healthy and free of pests.
