Updated: April 24, 2022

Cordyline Glauca is a popular indoor plant that can add a touch of natural beauty to any home or office. However, it is not immune to pests, and mealybugs are one of the most common problems that can affect the health and appearance of the plant. Mealybugs are tiny, white insects that feed on the sap of plants, causing yellowing and distortion of leaves, stunted growth, and even death if left untreated. In this article, we will discuss how to identify and get rid of mealybugs on Cordyline Glauca plant.

Identifying Mealybugs

Mealybugs are small, soft-bodied insects that are covered with a powdery, white wax. They are typically found in clusters on the undersides of leaves, where they feed on the sap of plants. Mealybugs excrete a sticky substance called honeydew, which can attract ants and lead to the growth of sooty mold on the leaves.

To identify mealybugs on your Cordyline Glauca plant, look for white, cotton-like masses on the undersides of leaves or at the base of the plant. You may also notice yellowing or distorted leaves, stunted growth, or black mold on the leaves.

Getting Rid of Mealybugs

There are several ways to get rid of mealybugs on Cordyline Glauca plant:

1. Manual Removal

The first step in controlling mealybugs is to manually remove them from the plant. This can be done by using a cotton swab dipped in rubbing alcohol to wipe off the insects from the leaves and stems. You can also use a toothbrush or a soft-bristled brush to gently scrub away the bugs.

2. Insecticidal Soap

Insecticidal soap is a safe and effective way to control mealybugs on Cordyline Glauca plant. It works by suffocating the insects, causing them to die. To use insecticidal soap, mix 2 tablespoons of soap with 1 quart of water and spray the solution on the plant, making sure to coat the undersides of leaves where mealybugs are most commonly found.

3. Neem Oil

Neem oil is a natural insecticide that can be used to control mealybugs on Cordyline Glauca plant. It works by disrupting the insect’s hormonal balance, causing them to stop feeding and reproducing. To use neem oil, mix 1-2 tablespoons of oil with 1 quart of water and spray the solution on the plant, paying special attention to the undersides of leaves. Repeat every 7-10 days until the infestation is under control.

4. Commercial Insecticides

If manual removal, insecticidal soap, or neem oil do not work, you may need to resort to chemical insecticides. However, it is important to choose a product that is safe for indoor use and specifically labeled for mealybugs on Cordyline Glauca plant. Follow the instructions carefully and use protective gear when applying the product.

Preventing Mealybugs

Preventing mealybugs from infesting your Cordyline Glauca plant is key to keeping it healthy and beautiful. Here are some tips to prevent mealybugs:

  • Inspect new plants before bringing them into your home or office.
  • Keep your plant clean by wiping down leaves with a damp cloth.
  • Avoid overwatering your plant, as this can create a humid environment that encourages mealybug growth.
  • Use a balanced fertilizer to keep your plant healthy and strong, which can help prevent infestations.


1. Can mealybugs harm humans?
