Most Common Praying Hands Plant Pests:
Identification and Treatment Guide

Updated: July 1, 2023

Praying Hands plants, also known as Maranta leuconeura, are popular houseplants known for their unique foliage and vibrant colors. However, like any other plant, they can fall victim to pests that can damage their health and appearance. In this article, we will discuss some of the most common pests that affect Praying Hands plants and provide a comprehensive guide on how to identify and treat them.

Spider Mites

Spider mites are tiny pests that can infest Praying Hands plants and cause significant damage if left untreated. These pests are not actual spiders but are rather classified as arachnids. They are usually found on the underside of leaves and can be identified by the fine webbing they produce.

Signs of spider mite infestation include yellowing or browning leaves, stippling (tiny white or yellow spots) on the foliage, and webbing on the plant. To treat spider mites, start by isolating the affected plant to prevent the infestation from spreading. Then, spray the plant with a solution of water and mild dish soap, making sure to cover both sides of the leaves. Repeat this treatment every few days until all signs of spider mites are gone.

Mealybugs

Mealybugs are another common pest that can plague Praying Hands plants. These small, soft-bodied insects have a white or grayish appearance and often gather in clusters on the stems and leaf axils of plants. They feed by piercing the plant tissue and sucking out sap.

If you notice cotton-like masses on your Praying Hands plant or see sticky honeydew residue on the leaves, it is likely that you have a mealybug infestation. To eliminate these pests, it is recommended to use a cotton swab dipped in rubbing alcohol to directly remove them from the plant. Additionally, you can use an insecticidal soap or neem oil spray to treat the affected areas. Repeat these treatments as necessary to completely eradicate the mealybugs.

Scale Insects

Scale insects are small, immobile pests that attach themselves to the stems and leaves of plants, including Praying Hands plants. They are usually brown or black in color and have a protective scale-like covering that shields their soft bodies.

To identify a scale infestation, look for small bumps or shells on the plant’s surface. These insects can cause stunted growth and yellowing of the leaves. To treat scale insects on your Praying Hands plant, use a cotton swab dipped in rubbing alcohol to remove them manually. You can also use horticultural oil or insecticidal soap to suffocate and kill the remaining scales. Regularly inspect your plant to catch any new infestations early on.

Aphids

Aphids are common pests that can affect a wide range of plants, including Praying Hands plants. These small insects feed on plant sap and reproduce rapidly, causing foliage distortion and stunted growth.

Aphids can be identified by their small size, usually ranging from green to black in color. They tend to congregate on new growth and the underside of leaves. To control aphid infestations, start by spraying your Praying Hands plant with a strong stream of water to dislodge the insects. Alternatively, you can use insecticidal soap or neem oil spray to kill them. Repeat these treatments as necessary until all signs of aphids are gone.

Fungus Gnats

Fungus gnats are tiny flying insects that are attracted to moist soil. While they don’t directly harm Praying Hands plants, their larvae can cause damage by feeding on the plant’s roots.

To identify fungus gnats, look for tiny flies hovering around your plant or resting on its foliage. You may also notice small, black larvae in the soil. To control fungus gnats, allow the soil to dry out between waterings to discourage their breeding. You can also use sticky traps or insecticidal soap to catch and kill the adult gnats. If the infestation is severe, consider repotting your Praying Hands plant with fresh, sterile soil.

Conclusion

Praying Hands plants are beautiful additions to any indoor space, but like all plants, they can be susceptible to pest infestations. By familiarizing yourself with the most common pests that affect these plants and taking appropriate measures to identify and treat them, you can ensure the health and longevity of your Praying Hands plant. Remember to regularly inspect your plant, provide proper care, and promptly address any signs of pest activity to maintain a thriving and pest-free Praying Hands plant.
