How to Get Rid of Lerps on Giant Taro Plant

Updated: August 12, 2022

If you’re a gardener or plant enthusiast, chances are you have come across lerps on your plants. These tiny, white, waxy insects can cause damage to your plants and be a nuisance to deal with. One plant that is particularly vulnerable to lerps is the giant taro plant. In this article, we’ll discuss what lerps are, how they affect giant taro plants, and most importantly, how to get rid of them.

What are Lerps?

Lerps are tiny insects that feed on the sap of plants. They are often found in clusters on the underside of leaves, where they form a protective waxy covering over themselves. This covering is called a lerp. The lerp serves as a shield against predators and environmental factors such as wind and rain.

Lerps can be found on many different types of plants, but they are particularly common on fruit trees and ornamental plants. They are usually white in color and can be mistaken for small bits of cotton or fuzz.

How Do Lerps Affect Giant Taro Plants?

Giant taro plants (Alocasia macrorrhizos) are native to Southeast Asia and are commonly grown as ornamental plants in gardens and parks. They are known for their large, showy leaves and can grow up to six feet tall.

Lerps can cause damage to giant taro plants by feeding on the sap of the leaves, which can lead to yellowing, wilting, and even death of the plant if left untreated. In addition to damaging the plant, lerps can also attract other pests such as ants.

How to Get Rid of Lerps on Giant Taro Plants

Luckily, there are several methods for getting rid of lerps on giant taro plants. Here are some effective ways to control these pesky insects:

1. Prune Infested Leaves

One of the easiest ways to get rid of lerps on giant taro plants is to prune the infested leaves. This will remove the majority of the lerps and prevent them from spreading to other parts of the plant. Be sure to dispose of the pruned leaves in a sealed bag or container to prevent the lerps from spreading.

2. Blast Them Off with Water

If pruning isn’t enough, you can try blasting the lerps off with a strong stream of water. This method is particularly effective for small infestations and can be repeated as needed.

3. Use Insecticidal Soap

Insecticidal soap is a natural alternative to chemical pesticides and can be effective in killing lerps on giant taro plants. Simply spray the affected areas with a solution of insecticidal soap and water, being sure to cover both the tops and undersides of the leaves. Repeat every few days until the infestation is under control.

4. Use Horticultural Oil

Horticultural oil is another natural option for controlling lerps on giant taro plants. It works by suffocating the insects and their eggs, preventing them from reproducing. Mix horticultural oil with water according to package instructions and spray onto the affected areas. Be sure to cover both sides of the leaves and repeat every few days until the infestation has been eliminated.
