How to Get Rid of Lerps on Colocasia Plant

Colocasia plants, also known as elephant ears or taro, are a popular choice for gardeners who want to add a tropical touch to their landscapes. However, these plants are susceptible to infestations by tiny insects called lerps. These pests can cause significant damage to the plant if left unchecked. In this article, we will discuss how to identify and get rid of lerps on your Colocasia plant.

What are Lerps?

Lerps are small insects that belong to the family Psyllidae. They are about 1/8 inch long and have a flattened, oval shape. Lerps are typically found on the undersides of leaves, where they feed on plant sap. They secrete a protective waxy coating over themselves that looks like small white bumps or scales. This coating is what gives them their name – lerps.

Identifying Lerps on Colocasia Plants

The first sign of a lerp infestation on your Colocasia plant is the presence of the white, waxy bumps on the undersides of leaves. These bumps can be difficult to spot, so it’s important to inspect your plants regularly. You may also notice yellowing or wilting of leaves, which is a sign that the lerps are causing damage to the plant’s vascular system.

How to Get Rid of Lerps on Colocasia Plants

There are several methods you can use to get rid of lerps on your Colocasia plant:

1. Prune Infected Leaves

The first step in treating a lerp infestation is to remove any infected leaves from the plant. Use sharp pruning shears to cut off affected leaves and dispose of them in the trash (not compost). This will help prevent the spread of lerps to other parts of the plant.

2. Blast the Plant with Water

Lerps are delicate insects that can be easily dislodged from the plant with a strong stream of water. Use a garden hose or sprayer to blast your Colocasia plant with water, paying special attention to the undersides of leaves where lerps tend to congregate. Repeat this process every few days until the infestation is under control.

3. Apply Insecticidal Soap

Insecticidal soap is a safe and effective treatment for lerp infestations on Colocasia plants. Look for a product that is specifically formulated for use on ornamental plants, and follow the instructions carefully. Most insecticidal soaps need to be applied every 7-10 days for several weeks to fully eradicate the infestation.

4. Use Neem Oil

Neem oil is another natural treatment for lerp infestations. It works by disrupting the insects’ feeding and reproductive systems, leading to their eventual death. Mix neem oil with water according to the instructions on the package, and spray your Colocasia plant thoroughly. Repeat this process every 7-10 days until the infestation is gone.
