If you’ve noticed small, white, waxy bumps on the leaves of your coontie plant, you may have a lerp infestation. These pests are actually tiny insects that feed on the sap of the plant and create these protective bumps to shield themselves from predators. While lerps won’t usually kill a coontie plant, they can cause stress and damage to the foliage, leading to a less healthy and attractive plant. Fortunately, there are several ways to get rid of lerps on your coontie plant.

Identify the Problem

Before you can effectively address a lerp infestation on your coontie plant, you need to be sure that’s what’s causing the issue. Lerps are small, white bumps that look like tiny pearls or grains of rice on the leaves of your plant. They can also be found on new growth or stems. If you’re not sure if your coontie plant has lerps or something else is causing the issue, take a closer look at the bumps. If you see tiny insects or a sticky residue around them, it’s likely lerps.

Remove by Hand

The easiest way to remove lerps from your coontie plant is by hand. Simply use a soft-bristled brush or cloth to gently scrub off the bumps. You may need to apply some pressure to break through the waxy coating that protects the lerps. Be sure to dispose of any removed lerps in a sealed plastic bag or container to prevent them from spreading.

Use Horticultural Oil

Horticultural oil is an effective treatment for lerps on coontie plants. This oil suffocates the insects and their protective coating, causing them to die off. To use horticultural oil, mix it according to the instructions and apply it directly to the affected areas of your coontie plant. Be sure to cover both the top and bottom of the leaves. Repeat this treatment every 7-10 days until the infestation is gone.

Apply Insecticidal Soap

Insecticidal soap is another option for getting rid of lerps on your coontie plant. This soap works by breaking down the protective coating on the lerps, leaving them vulnerable to dehydration and death. To use insecticidal soap, mix it according to the instructions and apply it directly to the affected areas of your coontie plant. Be sure to cover both the top and bottom of the leaves. Repeat this treatment every 7-10 days until the infestation is gone.

Encourage Natural Predators

One way to control a lerp infestation on your coontie plant is by encouraging natural predators to come in and feed on the insects. Ladybugs, lacewings, and parasitic wasps are all beneficial insects that will eat lerps. You can attract these predators to your garden by planting flowers that they like, such as daisies, marigolds, and yarrow.

Frequently Asked Questions

How do I prevent lerps from infesting my coontie plant?

The best way to prevent lerps from infesting your coontie plant is by keeping it healthy and well-maintained. Avoid overwatering or underwatering your plant, as this can create stress and make it more vulnerable to pests. Additionally, remove any dead or diseased foliage promptly and keep an eye out for any signs of infestation.

Are lerps harmful to humans?

No, lerps are not harmful to humans. They do not bite or sting and are generally considered harmless. However, if you’re allergic to insect bites or have sensitive skin, you may want to wear gloves when removing them by hand.

Can I use chemical pesticides to get rid of lerps on my coontie plant?

While chemical pesticides can be effective at controlling lerps, they can also harm beneficial insects and other wildlife in your garden. Additionally, some pesticides may not be safe for use on edible plants or may be harmful to pets and humans. It’s best to try non-toxic methods first and only use chemical pesticides as a last resort.
