Most Common Red Prayer Plant Pests:
Identification and Treatment Guide

Updated: July 12, 2023

Red prayer plants, also known as Maranta leuconeura, are popular houseplants valued for their striking foliage and ability to thrive in low-light conditions. However, like any other plant, red prayer plants can be susceptible to various pests that can harm their overall health and appearance. In this article, we will discuss the most common red prayer plant pests, how to identify them, and provide effective treatment options.

Spider Mites

Spider mites are tiny arachnids that can infest red prayer plants. They are difficult to spot with the naked eye but leave behind a fine webbing on the leaves. Infested leaves may also appear stippled or discolored, with a yellowish or bronzed appearance.

To treat spider mite infestations, start by isolating the affected plant to prevent the mites from spreading to other plants. Then, use a strong jet of water to wash off the mites from the leaves. Repeat this process every few days until the infestation is under control. Additionally, you can use insecticidal soap or neem oil spray to further combat these pests.

Mealybugs

Mealybugs are small, soft-bodied insects that often appear as white cottony masses on the stems and undersides of leaves. They feed on the plant sap, causing stunted growth and yellowing of the foliage. Mealybugs also produce a sticky substance called honeydew, which can attract ants and promote the growth of sooty mold.

To remove mealybugs from red prayer plants, gently wipe them off with a cotton swab dipped in rubbing alcohol or soapy water. If the infestation is severe, you may need to resort to using insecticidal soap or neem oil spray. Regularly inspect your plants for signs of mealybug activity and promptly treat any infestations to prevent further damage.

Aphids

Aphids are small, soft-bodied insects that can be found on the undersides of red prayer plant leaves. They come in various colors, including green, black, and brown. Aphids feed on the plant sap, causing distorted growth and yellowing of leaves. They also excrete honeydew, which can attract ants and encourage the growth of sooty mold.

To control aphid infestations, you can use a strong jet of water to dislodge them from the leaves. Alternatively, you can apply insecticidal soap or neem oil spray to eliminate these pests. Introducing natural predators such as ladybugs or lacewings can also help keep the aphid population in check.

Scale Insects

Scale insects are small, immobile pests that attach themselves to the stems and leaves of red prayer plants. They resemble small bumps or scales and can be brown, black, or white in color. Scale insects feed on plant sap and excrete a sticky substance called honeydew. The presence of scale insects can result in stunted growth, yellowing leaves, and leaf drop.

To remove scale insects from red prayer plants, gently scrape them off with a soft brush or cotton swab dipped in rubbing alcohol. For heavy infestations, you may need to apply insecticidal soap or neem oil spray. It is crucial to monitor your plants regularly and treat any scale insect infestations promptly to prevent further damage.

Fungus Gnats

Fungus gnats are small flying insects that resemble tiny mosquitoes. They are attracted to damp soil and lay their eggs in the potting mix of red prayer plants. The larvae feed on organic matter in the soil, including the plant’s roots. Signs of fungus gnat infestations include yellowing leaves, wilting, and a large number of adult gnats flying around the plant.

To control fungus gnats, allow the soil to dry out between waterings as they thrive in moist conditions. You can also use yellow sticky traps to catch the adult gnats and prevent them from laying eggs. To eliminate the larvae, apply a biological larvicide specifically designed for fungus gnats to the potting mix.

Conclusion

While red prayer plants are relatively easy to care for, they can still fall victim to a variety of pests. Spider mites, mealybugs, aphids, scale insects, and fungus gnats are some of the most common pests that can infest red prayer plants. Identifying these pests and promptly treating any infestations is essential to maintain the health and beauty of your plants. By following the treatment methods provided in this guide, you can effectively control and prevent pest problems, allowing your red prayer plants to thrive in your home or office space.
