Corn tree plants are beautiful indoor plants that can make your living space look cheerful and lively. However, like any other houseplant, they are susceptible to pests and diseases, one of which is spider mites. Spider mites are tiny pests that can cause significant damage to corn tree plants if left untreated. In this article, we will discuss how to get rid of spider mites in corn tree plant.

Identifying Spider Mites

Spider mites are tiny pests that are barely visible to the naked eye. They usually appear as small yellow, red, or green dots on the leaves of corn tree plants. As their name suggests, spider mites spin webs on the leaves and stems of the plant. These webs can be a sign of heavy infestations.

Steps to Get Rid of Spider Mites

Here are some steps you can take to get rid of spider mites in corn tree plant:

Step 1: Isolate the Infected Plant

If you have other houseplants, it’s essential to isolate the infected corn tree plant to prevent the spider mites from spreading to other plants. Place the infected plant in a separate room or area where it can receive proper treatment.

Step 2: Remove Infected Leaves

Spider mites usually start feeding on the lower leaves of corn tree plants and gradually work their way up. To prevent further damage, remove the infected leaves using a pair of scissors or pruning shears. Be sure to dispose of these leaves away from your other plants.

Step 3: Wash the Plant

Wash the plant with a strong spray of water using a hose or showerhead. This will help dislodge any remaining spider mites and their webs. Be sure to wash both the upper and lower surfaces of the leaves.

Step 4: Apply Insecticidal Soap

Insecticidal soap is an effective and safe way to get rid of spider mites in corn tree plant. It works by suffocating the pests and drying out their eggs. Follow the instructions on the label and apply the soap on both the upper and lower surfaces of the leaves. Repeat the application once a week until all spider mites are gone.

Step 5: Increase Humidity

Spider mites thrive in dry environments, so increasing humidity levels can help prevent further infestation. You can increase humidity by placing a humidifier near the plant or by misting the leaves with water regularly.

Preventing Spider Mites

Prevention is always better than cure, so here are some tips to prevent spider mites from infesting your corn tree plant:

  • Regularly inspect your plants for signs of spider mites and other pests.
  • Water your plants regularly and keep the soil moist but not waterlogged.
  • Avoid over-fertilizing your plants as this can attract pests.
  • Keep your plants in a well-ventilated area with good air circulation.
