Corn tree plants are a popular houseplant choice for their attractive foliage and easy care. However, like any plant, they can be susceptible to various pests that can damage their health and appearance. In this article, we will discuss the most common corn tree plant pests, how to identify them, and the best methods for treating them.

Spider Mites

Spider mites are one of the most common pests that affect corn tree plants. These tiny arachnids feed on the sap of the plant and can cause significant damage if left untreated. You may notice small brown spots on the leaves or a fine webbing on the undersides of the leaves.

To treat spider mites, you can use a miticide spray or simply wash the plant with water to knock them off. Make sure to remove any damaged leaves to prevent further infestation.

Mealybugs

Mealybugs are another common pest that can infest corn tree plants. These small, white insects feed on the sap of the plant and can cause wilting and yellowing of leaves. They also secrete a sticky substance called honeydew that can attract other pests.

To get rid of mealybugs, you can use a systemic insecticide or wipe them off with alcohol-soaked cotton swabs. It’s also important to keep your plant well-watered and fertilized to prevent stress that can make it more susceptible to infestation.

Scale Insects

Scale insects are another common pest that can affect corn tree plants. These small, oval-shaped insects attach themselves to the stems and branches of the plant and feed on its sap. They can cause yellowing of leaves and stunted growth if left untreated.

To treat scale insects, you can use a horticultural oil or insecticidal soap spray. Make sure to thoroughly coat all affected areas of the plant and repeat the treatment every two weeks until the infestation is gone.

Thrips

Thrips are tiny, narrow insects that feed on the sap of corn tree plants. They can cause silver or white streaks on the leaves and flowers and can also spread plant viruses.

To get rid of thrips, you can use a systemic insecticide or insecticidal soap. It’s also important to remove any affected leaves and flowers to prevent the spread of the infestation.
