Fishbone prayer plants, also known as Maranta leuconeura, are popular houseplants that are loved for their unique foliage and easy care. However, like any plant, they can be prone to pests. One pesky pest that can attach itself to the leaves of a fishbone prayer plant is lerp. Lerps are small, white, waxy bumps that appear on the underside of the leaves and can cause damage if left untreated. In this article, we will discuss how to get rid of lerps on fishbone prayer plants.

What are Lerps?

Lerps are the protective coverings created by certain insects as a means of protection from predators and environmental factors. They appear as small, white, waxy bumps on the leaves of a plant and can be mistaken for scales or even part of the plant’s natural structure. However, they are actually a sign of infestation and can cause damage to the plant if left untreated.

Identifying Lerps on Fishbone Prayer Plants

If you suspect that your fishbone prayer plant has lerps, it is important to identify them correctly in order to treat them effectively. Lerps on fishbone prayer plants typically appear as small, white or yellow bumps on the underside of the leaves. They can also be accompanied by sticky sap or honeydew, which is a sign that the insects are feeding on the plant’s sap.

How to Get Rid of Lerps on Fishbone Prayer Plants

Getting rid of lerps on fishbone prayer plants can be done through a combination of manual removal and insecticidal soap. Here are the steps you need to take:

  1. Inspect Your Plant: Start by inspecting your fishbone prayer plant for signs of infestation. Pay close attention to the underside of the leaves where lerps like to hide.

  2. Manually Remove Lerps: Use a cotton swab or your fingers to carefully remove the lerps from the leaves. Be gentle to avoid damaging the plant.

  4. Repeat as Necessary: Depending on the severity of the infestation, you may need to repeat this process several times in order to completely get rid of the lerps. Be sure to monitor your plant regularly and continue treating it until all signs of infestation are gone.
