Most Common Red Maranta Plant Pests:
Identification and Treatment Guide

Updated: July 9, 2023

Red Maranta, also known as Maranta leuconeura erythroneura, is a popular houseplant due to its stunning red veins that run through its leaves. However, like any other plant, the Red Maranta is susceptible to pests that can cause damage and hinder its growth. In this article, we will discuss some of the most common pests that affect Red Maranta plants, how to identify them, and the best treatment options.

Spider Mites

Spider mites are tiny pests that belong to the arachnid family. They are barely visible to the naked eye but can cause significant damage to Red Maranta plants. These pests feed on the sap of the plants, which weakens them and causes discoloration and wilting.

Identification: Spider mites leave behind fine webbing on the undersides of leaves, along with small yellow or brown spots. Upon closer inspection, you may be able to spot these tiny pests crawling around.

Treatment: To treat spider mites, first isolate the affected plant to prevent the infestation from spreading. Use a strong jet of water to wash off the mites from the leaves. You can also use insecticidal soap or neem oil spray to control their population. Repeat the treatment every few days until the infestation is eradicated.

Mealybugs

Mealybugs are another common pest that affects Red Maranta plants. These soft-bodied insects are covered in a white waxy substance, making them easy to identify. They feed on plant sap and reproduce rapidly, leading to an infestation if left untreated.

Identification: Mealybugs can be identified by their cotton-like appearance and their presence in clusters on the undersides of leaves and along stems. They leave behind sticky honeydew residue that attracts ants and can cause fungal growth.

Treatment: Start by removing the visible mealybugs manually using a cotton swab dipped in rubbing alcohol. Next, apply a mixture of water and mild dish soap directly to the affected areas. Repeat this process every few days until the infestation is under control. Neem oil can also be effective in treating mealybugs.

Scale Insects

Scale insects are small, immobile pests that attach themselves to the stems and leaves of Red Maranta plants. They have a protective shell-like covering that makes them appear as small bumps. Scale insects feed on plant sap and can cause yellowing, leaf drop, and overall decline in plant health.

Identification: Scale insects can be identified by their round or oval-shaped shell-like coverings. They are usually brown or tan in color and can be found along the stems and undersides of leaves.

Treatment: Use a cotton swab dipped in rubbing alcohol to remove the scale insects from the plant. Alternatively, you can use horticultural oil or insecticidal soap to suffocate them. Make sure to thoroughly cover all affected areas. Repeat the treatment every week for a few weeks to ensure complete eradication.

Fungus Gnats

Fungus gnats are small flying insects that are attracted to moist soil. While they don’t directly harm the Red Maranta plant, their larvae feed on organic matter in the soil, including the roots of the plant, leading to stunted growth.

Identification: Adult fungus gnats are tiny black flies that hover around the plant and can often be seen flying near the soil surface. The larvae are translucent and worm-like, found in the top layer of the soil.

Treatment: Allow the soil to dry out between waterings to discourage fungus gnat larvae from thriving. You can also use sticky traps placed near the plant to catch adult flies. If the infestation persists, consider using a biological control such as beneficial nematodes, which feed on the larvae.

Aphids

Aphids are small, soft-bodied insects that suck the sap from plants, causing stunted growth and distorted leaves. They reproduce rapidly and can quickly infest a Red Maranta plant if not treated promptly.

Identification: Aphids can be found in clusters on the undersides of leaves and along stems. They come in various colors, including green, black, yellow, or brown. Aphids excrete honeydew, which attracts ants and can lead to the growth of sooty mold.

Treatment: You can remove aphids by spraying water with a strong jet or by wiping them off with a cotton swab dipped in soapy water. Insecticidal soap or neem oil can also be effective in controlling aphids. Repeat the treatment every few days until the infestation is eliminated.

Conclusion

Keeping your Red Maranta plant free from pests is essential to ensure its health and longevity. Regularly inspecting your plant for signs of pests and taking immediate action when an infestation is detected is crucial. Remember to isolate the affected plant to prevent the spread of pests and always follow the instructions on any treatment products used. With proper care and attention, your Red Maranta plant will thrive and continue to display its stunning red veins for years to come.
