How to Get Rid of Lerps on Freshwater Plant

Updated: August 14, 2022

Freshwater plants are a beautiful addition to any aquarium or aquatic garden. However, they can be vulnerable to infestations of pests like lerps. These small, white, waxy structures can be found on the leaves of freshwater plants and are often accompanied by the presence of tiny insects. In this article, we will discuss how to get rid of lerps on freshwater plants and prevent them from coming back.

What are Lerps?

Lerps are protective coverings created by tiny insects called lerp psyllids. These insects feed on the sap of freshwater plants and excrete a sugary substance that they use to create their protective homes. The lerps can be white or brown and can be found on the underside or top of leaves. They are usually accompanied by the presence of small black, brown, or green insects that feed on the plant’s sap.

Why are Lerps Harmful?

Lerps can cause significant damage to freshwater plants if left untreated. The insects that create the lerps feed on the sap of the plant, which can weaken it and make it more susceptible to other diseases and pests. Additionally, the sugary excretions from the insects can attract other pests like ants and flies.

How to Get Rid of Lerps on Freshwater Plants

  1. Manual Removal: One effective way to remove lerps from freshwater plants is to manually remove them using a soft-bristled brush or toothbrush. Gently scrub the affected areas of the plant to remove the lerps and any accompanying insects. Be sure to dispose of any debris in a sealed bag or container to prevent re-infestation.

  2. Chemical Treatment: There are several chemical treatments available for getting rid of lerps on freshwater plants. These treatments can be purchased at most pet stores and aquarium supply stores. Follow the instructions carefully when using any chemical treatment, and be sure to remove any snails or other invertebrates from the tank before treatment.

  3. Biological Control: One natural way to get rid of lerps on freshwater plants is to introduce natural predators. Certain species of fish, like Siamese algae eaters and otocinclus, feed on the insects that create the lerps. Additionally, introducing beneficial insects like ladybugs or lacewing larvae to your aquatic garden can help control lerps.

  4. Preventative Measures: The best way to get rid of lerps on freshwater plants is to prevent them from occurring in the first place. Regularly inspect your plants for signs of infestation and remove any affected leaves as soon as possible. Keep your tank or aquatic garden clean and well-maintained, and avoid overfeeding your fish, which can attract pests.
