If you’re a gardener or have a green thumb, it’s likely that you’ve come across the pesky little insects called lerps on your Weigela plant. These small bugs can cause significant damage to your plants if left untreated. In this article, we’ll go over what lerps are and how to get rid of them.
Lerps are small, sap-sucking insects that attach themselves to the leaves of plants. They create a protective shield-like structure called a lerp, which helps them to hide from predators and harsh weather conditions. The lerps are made up of the insect’s waste and any materials it can find around the plant.
Lerps can be found on a variety of plants, including Weigela. They can cause damage to the plant by sucking out the sap from the leaves, which can lead to wilting, stunted growth or even death.
Lerps are often easy to spot on Weigela plants because they create a distinctive, white or brownish, dome-shaped shell over their bodies. You may also notice that the leaves of your plant have yellow spots or are curling up at the edges. If you look closely at the underside of the leaves, you may see the small insects or their shed skins.
There are several methods you can use to get rid of lerps on Weigela plants:
One way to control lerps is to prune away any affected branches. This method is best used when only a few branches have been affected by the insects. Be sure to dispose of any pruned branches in a sealed plastic bag so that the lerps don’t spread to other plants.
Insecticidal soap is a safe and effective way to get rid of lerps on Weigela plants. The soap works by suffocating the insects, causing them to die. You can purchase insecticidal soap at most garden centers or online.
To use insecticidal soap, mix it with water according to the manufacturer’s instructions and spray it onto the affected plant. Be sure to cover both the top and bottom of the leaves, as well as the stems. Repeat the treatment every few days until the lerps are gone.
Horticultural oil is another option for controlling lerps on Weigela plants. The oil works by suffocating the insects in a similar way to insecticidal soap. You can purchase horticultural oil at most garden centers or online.
To use horticultural oil, mix it with water according to the manufacturer’s instructions and spray it onto the affected plant. Be sure to cover both the top and bottom of the leaves, as well as the stems. Repeat the treatment every few days until the lerps are gone.
Introducing predatory insects to your garden can be an effective way to control lerps naturally. Ladybugs and lacewings are two examples of predatory insects that eat lerps. You can purchase them online or at some garden centers.
Be sure to release the predatory insects near the affected plant and follow up with additional releases as needed.
