Common Calathea Ornata Plant Pests:
Prevention and Control Methods

Updated: May 4, 2023

Calathea Ornata, also known as the Pinstripe Plant, is a popular houseplant that is cherished for its stunning foliage. This plant is native to South America and features dark green leaves with pink stripes that run parallel to the veins. However, like any other plant, Calathea Ornata is susceptible to pests that can damage its appearance and health. In this article, we will discuss the common pests that attack Calathea Ornata and how to prevent and control them.

Common Calathea Ornata Plant Pests

1. Spider Mites

Spider mites are tiny arachnids that can cause damage to the leaves of Calathea Ornata. They are often found on the undersides of leaves where they suck the sap from the foliage. As a result, you will notice yellowing or browning of leaves, stunted growth, and webbing on the leaves.

2. Scale Insects

Scale insects are small, oval-shaped pests that attach themselves to the stems and leaves of Calathea Ornata. They suck the sap from the plant, causing yellowing or dropping of leaves and stunted growth. Scale insects also secrete a sticky substance called honeydew that attracts ants and promotes the growth of sooty mold.

3. Mealybugs

Mealybugs are soft-bodied insects that resemble cotton balls. They feed on the sap of the plant and cause stunted growth, yellowing or browning of leaves, and wilting. Mealybugs also secrete honeydew which attracts ants and promotes sooty mold growth.

4. Fungus Gnats

Fungus gnats are tiny black flies that lay their eggs in moist soil. The larvae feed on the roots of Calathea Ornata, causing stunted growth, wilting, and yellowing or browning of leaves. Adult fungus gnats do not cause direct damage to the plant but can be a nuisance when they fly around.

Prevention and Control Methods

Prevention is key when it comes to pest control in houseplants. Here are some tips to prevent pests from attacking your Calathea Ornata:

  • Inspect your plant regularly for signs of pests.
  • Keep your plant in a well-ventilated area with good air circulation.
  • Avoid overwatering your plant as humidity can attract pests.
  • Use sterile potting soil when repotting your plant.
  • Do not overcrowd your plants as this can create a favorable environment for pests.

If pests do attack your Calathea Ornata, here are some control methods that you can use:

1. Manual Removal

Manual removal involves physically removing the pests from your plant using a damp cloth or cotton swab dipped in alcohol. This method works well for scale insects and mealybugs that attach themselves to the stem or leaves.

2. Insecticidal Soap

Insecticidal soap is a natural pest control method that works by suffocating the pests. It is safe for use on Calathea Ornata but should be used according to the manufacturer’s instructions.

3. Neem Oil

Neem oil is a natural pesticide derived from neem trees. It works by disrupting the feeding behavior of pests and inhibiting their ability to reproduce. Neem oil should be diluted with water before application and should not be used in direct sunlight.

4. Beneficial Insects

Beneficial insects such as ladybugs and lacewings feed on common houseplant pests like spider mites and mealybugs. You can purchase these insects online or at your local garden center and introduce them into your indoor garden.
