How to Get Rid of Scales on Colocasia Plant

Updated: October 22, 2022

Colocasia plants are a popular choice for gardeners and houseplant enthusiasts due to their striking foliage and low maintenance requirements. However, like all plants, they are not immune to pest infestations. One common pest that can plague colocasia plants is scales. Scales are small, hard-shelled insects that feed on the sap of plants, causing damage and potentially killing the plant if left untreated. In this article, we will discuss how to get rid of scales on your colocasia plant.

Identifying Scales on Colocasia Plant

Before we dive into treatment options, it’s essential to know what scales look like and how to identify them on your colocasia plant. Scales are tiny insects that appear as small bumps or scales on the surface of leaves or stems. They can be brown, black, or tan and may have a waxy or shiny appearance. If you notice these bumps on your plant, it’s likely you have a scale infestation.

Treatment Options for Scales on Colocasia Plant

There are several treatment options for scales on colocasia plants. The most effective method will depend on the severity of the infestation and personal preference.

1. Manual Removal

One way to get rid of scales is by manually removing them from the plant. This method is best for small infestations and can be done using a soft-bristled brush or cotton swab dipped in rubbing alcohol. Gently rub the affected areas with the brush or cotton swab until the scales come off. Be sure to dispose of the scales properly to prevent reinfestation.

2. Insecticidal Soap

Another treatment option is using insecticidal soap. This method involves spraying the plant with a solution made from liquid dish soap and water. Mix one tablespoon of dish soap with one quart of water and spray the entire plant, focusing on the underside of leaves where scales tend to hide. Repeat this process every five to seven days until the infestation is gone.

3. Horticultural Oil

Horticultural oil is another effective treatment for scales on colocasia plants. This method involves spraying the plant with a mixture of oil and water, suffocating the scales and preventing them from feeding on the plant. Mix two tablespoons of oil with one quart of water and spray the entire plant, focusing on the underside of leaves. Repeat this process every seven to ten days until the infestation is gone.

4. Chemical Insecticides

Chemical insecticides are another option for treating scale infestations. However, they should only be used as a last resort as they can harm beneficial insects and have potential health risks. If you choose to use chemical insecticides, be sure to follow the instructions carefully and wear protective gear such as gloves and a mask.

  • Keep plants healthy by providing adequate sunlight, water, and nutrients
  • Avoid overcrowding plants as this can lead to increased pest problems
  • Quarantine new plants before introducing them into your garden or home
  • Clean gardening tools regularly to prevent the spread of pests
