How to Get Rid of Lerps on Evergreen Plant

These insects are called lerps, and they are a common problem for evergreen plants. Lerps are sap-sucking insects that feed on the leaves of evergreen plants, causing damage to the foliage and weakening the plant. In this article, we will discuss how to get rid of lerps on evergreen plants.

What are Lerps?

Lerps are small, white, powdery-looking insects that feed on the leaves of evergreen plants. They are sap-sucking insects that create a protective cover over themselves by using a sugary substance called honeydew. This protective cover is called a lerp. The lerp not only protects the insect from predators but also helps it to retain moisture.

How to Identify Lerps

Lerps are easy to identify because of the protective cover they create over themselves. The lerp appears as a small, white, powdery-looking bump on the leaf of the evergreen plant. If you look closely, you can see the insect inside the lerp.
