Common Aralia Plant Pests:
Prevention and Control Methods

Updated: May 1, 2023

Aralia plants, also known as Polyscias, are popular houseplants that can add a tropical touch to any home. However, like any other plant, Aralias are susceptible to pests that can cause severe damage if left uncontrolled. In this article, we’ll discuss the most common Aralia plant pests and how to prevent and control them.

Common Aralia Plant Pests

Spider Mites

Spider mites are tiny pests that suck the sap from Aralia plants, causing the leaves to turn yellow and fall off. They thrive in hot and dry conditions, making indoor environments ideal for their growth. You can identify spider mites by their fine webbing on the leaves.

Mealybugs

Mealybugs are small, white, fluffy insects that suck the sap from the Aralia plant’s leaves and stems. They secrete a sticky substance called honeydew that attracts ants and promotes the growth of sooty mold.

Scale Insects

Scale insects are small, oval-shaped pests that attach themselves to the Aralia plant’s stems and leaves. They feed on the sap, causing the leaves to turn yellow and fall off. Scale insects secrete a sticky substance called honeydew that attracts ants and promotes the growth of sooty mold.

Prevention Methods

Preventing pest infestation is always better than controlling it. Here are some preventive measures you can take to keep your Aralia plant healthy:

  • Inspect new plants: Before bringing a new plant home, inspect it thoroughly for any signs of pest infestation.
  • Isolate infected plants: If you notice any signs of pest infestation, isolate the infected plant immediately to prevent the spread of pests.
  • Keep the environment clean: Regularly clean the leaves and stems of your Aralia plant with a damp cloth or sponge to remove any dust or debris that can attract pests.
  • Maintain proper humidity: Spider mites thrive in hot and dry conditions. To prevent their growth, maintain proper humidity levels in your home by misting your Aralia plant regularly.
  • Avoid overwatering: Overwatering can cause root rot, which weakens the plant’s immune system and makes it more susceptible to pest infestation.
  • Use organic fertilizers: Chemical fertilizers can weaken the plant’s immune system, making it more vulnerable to pest attacks. Instead, use organic fertilizers to promote healthy growth.

Control Methods

If you notice any signs of pest infestation despite taking preventive measures, here are some control methods you can use:

  • Manual removal: Use a cotton swab dipped in alcohol to manually remove mealybugs and scale insects from your Aralia plant. You can also use a strong stream of water to wash away spider mites.
  • Insecticidal soap: Insecticidal soap is an effective control method for mealybugs and spider mites. Spray the solution directly on the affected areas of your Aralia plant.
  • Neem oil: Neem oil is a natural insecticide that can control mealybugs, spider mites, and scale insects. Mix neem oil with water and spray it on your Aralia plant.
  • Beneficial insects: Introducing beneficial insects like ladybugs and lacewings into your home can help control pest infestation in your Aralia plant.

FAQ

A: It’s best to inspect your Aralia plant at least once a week for any signs of pest infestation.
