Elodea plants are popular choices for aquariums and backyard ponds due to their attractive appearance and ease of care. However, these plants can sometimes fall prey to a common pest known as lerps. Lerps are small, white, waxy structures that cover the leaves of the plant and can cause damage if left unchecked. In this article, we will discuss how to get rid of lerps on elodea plants.

What are Lerps?

Lerps are small, white, waxy structures that cover the leaves of elodea plants. They are created by tiny insects called psyllids, which feed on the sap of the plant. The psyllids secrete a sugary substance that hardens into a protective covering over their bodies. The lerps can be unsightly and can cause damage to the plant if left untreated.

How to Identify Lerps

Lerps are easy to identify on elodea plants. They appear as small, white, waxy structures on the leaves of the plant. The lerps can range in size from very small to several millimeters in diameter. You may also notice that the leaves of the plant have become distorted or discolored.

How to Get Rid of Lerps

Getting rid of lerps on elodea plants requires a multi-step approach. Here are some steps you can take to eliminate these pests:

Step 1: Remove Infested Leaves

The first step in getting rid of lerps is to remove any infested leaves from the plant. Use a pair of scissors or pruning shears to carefully cut off any leaves that have lerps present on them. Be sure to dispose of these leaves in a sealed plastic bag and throw them away in the trash.

Step 2: Clean the Plant

After removing any infested leaves, it’s important to clean the remaining plant thoroughly. Use a gentle stream of water from a hose or sink to wash the leaves of the plant. Be sure to pay special attention to the undersides of the leaves, where lerps may be hiding.

Step 3: Apply Insecticide

If cleaning the plant does not eliminate the lerps, you may need to apply an insecticide. There are several products available that are effective against psyllids and lerps. Be sure to choose a product that is safe for use on aquatic plants and follow the instructions carefully.

Step 4: Monitor the Plant

After treating the elodea plant for lerps, it’s important to monitor it closely for any signs of reinfestation. Check the plant daily for any new lerps or damaged leaves. If you notice any new infestations, repeat the steps above.
