Common Calathea Zebrina Plant Pests:
Prevention and Control Methods

Calathea Zebrina, also known as the Zebra plant, is a popular houseplant due to its striking foliage. However, like all plants, it is susceptible to pests. In this article, we will discuss the most common Calathea Zebrina plant pests and how to prevent and control them.

Spider Mites

Spider mites are tiny pests that feed on the sap of plants, causing yellowing leaves and webbing on the foliage. To prevent spider mites from infesting your Calathea Zebrina, make sure to keep the humidity levels high. You can do this by placing a humidifier near your plant or misting it regularly. Spider mites thrive in dry conditions, so keeping the air moist will deter them.

If you notice spider mites on your Calathea Zebrina, isolate the plant immediately to prevent them from spreading to other plants. Use a spray bottle filled with water and a few drops of dish soap to spray the foliage, making sure to cover both the top and bottom of the leaves. Repeat this process every three days until the spider mites are gone.

Mealybugs

Mealybugs are white, fluffy insects that feed on plant sap and produce honeydew, attracting ants and causing black mold growth. They can be found on the leaves, stems, and roots of plants. To prevent mealybugs from infesting your Calathea Zebrina, inspect your plant regularly for signs of infestation.

If you notice mealybugs on your Calathea Zebrina, remove them using a cotton swab dipped in rubbing alcohol. You can also use insecticidal soap or neem oil to treat the infestation. Make sure to follow the instructions carefully and apply the treatment every 7-10 days until the mealybugs are gone.

Fungus Gnats

Fungus gnats are small black flies that live in moist soil and feed on decaying organic matter. They can be a nuisance to houseplants as they lay their eggs in soil, which hatch into larvae that feed on plant roots. To prevent fungus gnats from infesting your Calathea Zebrina, let the soil dry out slightly between waterings.
