Most Common Raven Zz Plant Pests:
Identification and Treatment Guide

Updated: July 14, 2023

The Raven ZZ plant, scientifically known as Zamioculcas zamiifolia ‘Raven’, is an increasingly popular houseplant due to its unique dark foliage and low-maintenance nature. However, like any other plant, the Raven ZZ plant is susceptible to pests that can cause damage if not properly identified and treated. In this article, we will discuss the most common pests that affect the Raven ZZ plant and provide a comprehensive guide on their identification and treatment.

Spider Mites

Spider mites are tiny pests that belong to the arachnid family. They are common pests that infest many indoor plants, including the Raven ZZ plant. These pests are hardly visible to the naked eye but can cause significant damage if left untreated.

Identification: Spider mites typically leave behind small white or yellow spots on the leaves of the Raven ZZ plant. As the infestation progresses, you may notice fine webbing between leaves and along the stems. If you suspect spider mites, use a magnifying glass to examine the undersides of leaves for tiny moving dots.

Treatment: To control spider mites, begin by isolating the affected plant to prevent further spread. Use a strong stream of water to rinse off the mites from the plant, paying particular attention to the undersides of leaves. For severe infestations, consider using insecticidal soap or neem oil spray, following package instructions carefully.

Mealybugs

Mealybugs are another common pest that can affect the Raven ZZ plant. These soft-bodied insects are often found in clusters and can cause significant damage by feeding on the plant’s sap.

Identification: Mealybugs appear as tiny white or gray insects with a cotton-like waxy covering. They usually congregate in protected areas such as leaf axils or along stems. Infested plants may exhibit yellowing leaves, leaf drop, and sticky honeydew residue.

Treatment: To eliminate mealybugs, start by isolating the affected plant to prevent the infestation from spreading. Use a cotton swab dipped in rubbing alcohol to manually remove individual mealybugs. For larger infestations, consider using insecticidal soap or neem oil spray, ensuring thorough coverage of all plant surfaces.

Scale Insects

Scale insects are small, immobile pests that often go unnoticed until their numbers have multiplied significantly. These pests attach themselves to the stems and leaves of the Raven ZZ plant, sucking out its sap and weakening the plant.

Identification: Scale insects can appear as tiny bumps or shells on the plant’s foliage. They come in various colors, including brown, black, or white. Infested plants may exhibit yellowing leaves, stunted growth, and a sticky residue known as honeydew.

Treatment: Start by manually removing scale insects using a cotton swab dipped in rubbing alcohol. For larger infestations, use insecticidal soap or neem oil spray, making sure to thoroughly coat all affected areas. Repeat treatments may be necessary to completely eradicate the pests.

Fungus Gnats

Fungus gnats are small flies that resemble tiny mosquitoes. While they do not directly harm the Raven ZZ plant, their larvae can damage the plant’s roots by feeding on organic matter and causing root rot.

Identification: Fungus gnats are often seen flying around the soil surface of potted plants. The larvae are small white worms that can be found in the top layer of soil. Infested plants may exhibit yellowing leaves, wilting, and stunted growth.

Treatment: To control fungus gnats, start by allowing the soil to dry out between waterings to discourage their breeding. Use yellow sticky traps placed near the soil surface to catch adult gnats. If the infestation persists, consider using a biological control such as beneficial nematodes or applying a soil drench with Bacillus thuringiensis israelensis (BTI) to kill the larvae.

Aphids

Aphids are soft-bodied insects that can quickly multiply and infest the Raven ZZ plant. They feed on the plant’s sap and can transmit diseases while causing deformations and stunted growth.

Identification: Aphids are small, pear-shaped insects that come in various colors, including green, black, or brown. They can be found congregating on new growth, undersides of leaves, or along stems. Infested plants may exhibit distorted leaves, curling, and a sticky honeydew residue.

Treatment: Start by manually removing aphids using a strong stream of water or by gently wiping them off with a damp cloth. For larger infestations, use insecticidal soap or neem oil spray, ensuring thorough coverage of all affected areas. Repeat treatments may be necessary to completely eliminate the pests.

In conclusion, while the Raven ZZ plant is generally a resilient and low-maintenance houseplant, it is not immune to common pests. Regular inspection and early detection are essential for effective pest control. By promptly identifying and treating these common pests – spider mites, mealybugs, scale insects, fungus gnats, and aphids – you can ensure your Raven ZZ plant remains healthy and vibrant. Remember to always follow package instructions when using any insecticides or treatments to protect both your plants and yourself.
