Most Common Monkey Tail Plant Pests:
Identification and Treatment Guide

Updated: July 19, 2023

Monkey Tail plants, also known as Monkey’s Tail cactus (Hildewintera colademononis), are a unique and popular addition to many indoor gardens. With their long, trailing stems covered in soft white spines, they add a touch of whimsy and charm to any space. However, like any plant, Monkey Tail plants are susceptible to pests. In this article, we will explore the most common pests that affect Monkey Tail plants and provide a guide for their identification and treatment.

Mealybugs

Mealybugs are one of the most common pests that infest Monkey Tail plants. These small, soft-bodied insects are covered in a white, cotton-like substance, which makes them easy to identify. Mealybugs feed on the sap of the plant, causing stunted growth and yellowing leaves.

To treat a mealybug infestation, start by isolating the affected plant to prevent the infestation from spreading to other plants. Then, use a cotton swab dipped in rubbing alcohol to remove the mealybugs from the plant. Pay close attention to the crevices between stems and leaves, as mealybugs tend to hide in these areas. Repeat this process every few days until all signs of mealybugs are gone.

Scale Insects

Scale insects are another common pest that can affect Monkey Tail plants. These tiny insects attach themselves to the stems and leaves of the plant and feed on its sap. They appear as small bumps or scales on the plant’s surface and can range in color from brown to black.

To treat scale insects, start by removing them manually with a cotton swab dipped in rubbing alcohol or by gently scraping them off with a soft brush. If the infestation is severe, you may need to use an organic insecticidal soap or horticultural oil spray. Be sure to follow the instructions on the product label and repeat the treatment as necessary.

Spider Mites

Spider mites are microscopic pests that can cause significant damage to Monkey Tail plants. They are not actually spiders but are related to spiders and ticks. Spider mites thrive in warm, dry conditions and can quickly multiply, leading to an infestation. These pests feed on the plant’s sap, causing yellowing leaves, webbing, and eventual plant death.

To treat a spider mite infestation, start by isolating the affected plant and increasing humidity around it. You can do this by placing a tray filled with water near the plant or by misting the leaves with water regularly. Additionally, you can use an organic insecticidal soap or horticultural oil spray to control spider mites. Be sure to cover both sides of the leaves thoroughly and repeat the treatment as necessary.

Aphids

Aphids are small insects that feed on the sap of Monkey Tail plants. They are typically green or brown in color and cluster around new growth, such as young leaves and flower buds. Aphids can cause distorted growth, yellowing leaves, and the development of sooty mold.

To treat an aphid infestation, start by washing the affected plant with a strong stream of water to dislodge the insects. You can also use insecticidal soap or neem oil spray to control aphids. Repeat the treatment every few days until all signs of aphids are gone.

Fungus Gnats

Fungus gnats are small flies that are attracted to moist soil. While they don’t directly harm Monkey Tail plants, their larvae can feed on the plant’s roots, causing stunted growth and wilting.

To control fungus gnats, start by allowing the soil to dry out between waterings as these pests thrive in moist conditions. You can also use yellow sticky traps to catch adult fungus gnats and decrease their population. If the infestation persists, consider using a biological control agent, such as beneficial nematodes, to target the larvae in the soil.

Prevention is Key

Preventing pest infestations is always preferable to treating them. Here are some tips to prevent pests from attacking your Monkey Tail plants:

  • Regularly inspect your plants for signs of pests.
  • Keep your plants in a well-ventilated area with good air circulation.
  • Avoid overwatering, as excessive moisture can attract pests.
  • Quarantine new plants before introducing them to your existing collection.
  • Keep a clean gardening environment by removing dead leaves and debris.

By following these prevention tips and promptly treating any pest issues that arise, you can ensure the health and vitality of your Monkey Tail plants. Remember, early detection and intervention are crucial for successful pest control.
