Most Common Silver Queen Plant Pests:
Identification and Treatment Guide

Updated: July 13, 2023

Silver Queen plants (Aglaonema) are popular houseplants known for their beautiful foliage and low-maintenance requirements. However, like any other plant, they can be susceptible to various pests that can damage their health and appearance. In this article, we will explore some of the most common silver queen plant pests, how to identify them, and effective treatment methods.

Aphids

Aphids are tiny, soft-bodied insects that commonly infest silver queen plants. They feed on the sap of the leaves, causing them to become distorted and yellowed. These pests reproduce rapidly, so it’s crucial to take immediate action upon detection.

Identification: Aphids are usually found in clusters on the undersides of leaves. They come in various colors, including green, black, brown, or yellow. If you notice sticky honeydew on the leaves or a sooty mold growth, it’s a sign of aphid infestation.

Treatment: Start by spraying a strong stream of water on the affected leaves to dislodge the aphids. You can also introduce natural predators such as ladybugs or lacewings to control their population. In severe cases, insecticidal soap or neem oil can be used as a last resort.

Spider Mites

Spider mites are arachnids that can cause significant damage to silver queen plants if not addressed promptly. These tiny pests thrive in warm and dry conditions, making indoor environments ideal for their infestation. They feed on the sap of the leaves, resulting in stippling or yellow spots.

Identification: Spider mites are difficult to spot with the naked eye due to their small size. However, you may notice fine webbing on the undersides of leaves or small red or brown dots crawling on the foliage.

Treatment: Increase humidity around the plant by misting the leaves regularly. This helps deter spider mites as they prefer dry conditions. Additionally, you can prune heavily infested leaves and apply insecticidal soap or neem oil to control their population.

Mealybugs

Mealybugs are common pests that affect a wide range of plants, including silver queen plants. They are small, soft-bodied insects covered in a cotton-like wax coating. Mealybugs suck the sap from the leaves and stems, causing stunted growth and yellowing.

Identification: Look for white, fuzzy clusters on the undersides of leaves or along the stems. Mealybugs often hide in leaf axils or other hard-to-reach areas of the plant. They leave behind sticky honeydew and may attract ants.

Treatment: Isolate the infested plant immediately to prevent the spread of mealybugs to other plants. Remove mealybugs manually using a cotton swab dipped in rubbing alcohol or soapy water. Regularly inspect the plant for any signs of reinfestation and repeat the treatment if necessary.

Scale Insects

Scale insects are small, immobile pests that attach themselves to the stems and leaves of silver queen plants. They have a protective shell-like covering that allows them to blend in with the plant’s surface. These pests feed on the plant’s sap, causing yellowing, wilting, and overall decline in health.

Identification: Scale insects come in different colors and sizes, ranging from small brown bumps to larger tan or white scales. They can be found on both sides of leaves, along stems, or even on the soil surface.

Treatment: Use a soft brush or sponge dipped in soapy water to gently scrub off the scale insects from the plant’s surface. For severe infestations, you may need to use horticultural oil or insecticidal soap following the manufacturer’s instructions. Repeat the treatment if necessary to ensure complete elimination.

Fungus Gnats

Fungus gnats are small flying insects that infest the soil of silver queen plants. While they don’t directly harm the plant, their larvae feed on the roots, causing damage and stunted growth. Fungus gnats are attracted to moist soil, making overwatering a common cause of their infestation.

Identification: Look for tiny black flies hovering around the plant or crawling on the soil surface. The larvae are translucent and worm-like, often found in the top layer of the soil.

Treatment: Allow the soil to dry out between waterings to discourage fungus gnat breeding. Sticky traps placed near the plant can help catch adult flies. You can also use biological controls such as beneficial nematodes or predatory mites to target the larvae and prevent further infestation.

Conclusion

Keeping your silver queen plants free from pests is crucial to ensure their health and longevity. Regular inspection and early detection are key in preventing severe infestations. Remember to provide optimal growing conditions, such as proper watering and humidity levels, as healthy plants are less susceptible to pests. By following the identification and treatment methods discussed in this guide, you can effectively combat common silver queen plant pests and enjoy thriving green foliage in your home.
