Most Common Red Nerve Plant Pests:
Identification and Treatment Guide

Updated: July 25, 2023

Red Nerve plants, also known as Fittonias, are popular houseplants due to their vibrant and colorful foliage. Their distinctive red veins running through the leaves make them a stunning addition to any indoor space. However, like any other plant, they are susceptible to pests that can damage their health and appearance.

In this article, we will discuss the most common pests that affect Red Nerve plants and provide a comprehensive guide on how to identify and treat these pests effectively.

Aphids

Aphids are small, soft-bodied insects that feed on the sap of plants. They are commonly found on the undersides of leaves and can reproduce rapidly, causing significant damage to Red Nerve plants if left untreated. You can identify aphids by their small size (usually around 1-2 mm), pear-shaped bodies, and various colors such as green, black, or brown.

To control aphids on your Red Nerve plant, start by physically removing them with a strong stream of water or by wiping the leaves with a damp cloth. Additionally, you can use insecticidal soap or neem oil spray to effectively eliminate aphids. Repeat the treatment every few days until the infestation is under control.

Spider Mites

Spider mites are tiny arachnids that often infest Red Nerve plants. They are not actual spiders but are closely related to ticks and spiders. These pests are known for their ability to spin fine webs on the leaves, which can be one of the first signs of an infestation. Spider mites are extremely small (about 0.5 mm) and can be difficult to spot without magnification.

To treat spider mite infestations, first isolate the affected plant to prevent the mites from spreading to other nearby plants. Then, wash the leaves with a mixture of mild soap and water to dislodge the mites. For severe infestations, you can use insecticidal soap or neem oil spray. Make sure to thoroughly cover both sides of the leaves. Repeat the treatment every few days until the spider mites are eradicated.

Mealybugs

Mealybugs are another common pest that can plague Red Nerve plants. They are small, soft-bodied insects covered in a white, cottony substance that resembles tiny balls of cotton. Mealybugs typically congregate on the undersides of leaves, stems, and leaf axils.

To get rid of mealybugs on your Red Nerve plant, start by physically removing them with a cotton swab dipped in rubbing alcohol or a mixture of dish soap and water. Pay close attention to concealed areas where mealybugs tend to hide. For larger infestations, you can use insecticidal soap or neem oil spray. Apply the treatment every few days until the mealybugs are gone.

Scale Insects

Scale insects are small, immobile pests that attach themselves to the stems and leaves of Red Nerve plants. They appear as tiny bumps or shells on the plant’s surface and can range in color from brown to yellow. Scale insects feed on plant sap and can weaken the Red Nerve plant over time.

To treat scale infestations, scrape off the scales using a soft brush or your fingernail. Be gentle to avoid damaging the plant’s tissues. After removing the scales, wipe the affected areas with a cloth soaked in rubbing alcohol to kill any remaining pests. Repeat this process regularly until the scale insects are eliminated.

Fungus Gnats

Fungus gnats are small flying insects that often infest houseplants, including Red Nerve plants. They are attracted to moist soil and organic matter and lay their eggs in the potting mix. The larvae of fungus gnats feed on the plant’s roots, which can lead to root damage and poor plant health.

To control fungus gnats, allow the top layer of soil to dry out between watering to discourage their reproduction. You can also use sticky traps to catch adult gnats in midair. For severe infestations, consider using a biological control agent such as beneficial nematodes, which prey on the gnat larvae in the soil.

In conclusion, Red Nerve plants are prone to various pests that can harm their health and appearance. By promptly identifying and treating these common pests such as aphids, spider mites, mealybugs, scale insects, and fungus gnats, you can ensure the longevity and vitality of your Red Nerve plant. Remember to always monitor your plants regularly and take necessary measures to prevent and control pest infestations.
