How to Get Rid of Lerps on Dusty Miller Plant

Dusty Miller plants, also known as Jacobaea maritima, are beautiful perennials that are popular for their silvery-gray foliage. Unfortunately, these plants are often susceptible to infestations of tiny insects called lerps. These pests create a sticky, sugary substance that covers the leaves of the plant, which can be unsightly and can eventually kill the plant if left untreated. In this article, we will discuss how to get rid of lerps on your Dusty Miller plant.

Identify the Infestation

Before you can start treating your Dusty Miller plant for lerps, you need to make sure that you have correctly identified the infestation. Lerps are tiny insects that create small, white, oval-shaped structures on the underside of leaves. These structures are made from a sugary substance and provide a protective shell for the insect inside.

To check for lerps on your Dusty Miller plant, carefully examine the underside of the leaves. You may need to use a magnifying glass or a flashlight to see them clearly. If you see any small, white, oval-shaped structures, then your plant is likely infested with lerps.

Remove Infected Leaves

The first step in getting rid of lerps on your Dusty Miller plant is to remove any infected leaves. This will help to prevent the spread of the infestation to other parts of the plant. Carefully cut off any leaves that have lerps or lerp structures on them using a pair of sharp scissors or pruning shears.

Be sure to dispose of these leaves carefully so that you do not accidentally spread the infestation to other plants in your garden. You can either burn them or put them in a sealed plastic bag and throw them away.

Wash the Plant

Once you have removed all infected leaves, it is time to wash your Dusty Miller plant. This will help to remove any remaining lerps, as well as any sticky residue that they may have left behind.

To wash your plant, fill a bucket with warm water and add a few drops of dish soap. Use a soft cloth or sponge to gently wash the leaves of the plant, making sure to cover both the top and bottom surfaces. Rinse the plant thoroughly with clean water and let it dry completely before returning it to its original location.

Apply Insecticidal Soap

If the infestation is severe or if washing the plant does not completely get rid of the lerps, you may need to use an insecticidal soap. Insecticidal soaps are specially formulated to kill insect pests like lerps while being safe for plants and the environment.

To apply insecticidal soap to your Dusty Miller plant, follow the instructions on the packaging carefully. Generally, you will mix the soap with water in a spray bottle and then spray the solution onto the leaves of the plant, making sure to cover both the top and bottom surfaces.

Be sure to read and follow all instructions carefully, as using too much insecticidal soap can be harmful to your plants.
