Most Common Fittonia Nerve Plant Pests:
Identification and Treatment Guide

Updated: March 28, 2022

Fittonia nerve plants, also known as mosaic plants, are popular houseplants due to their striking appearance and ease of care. However, like any plant, they can be susceptible to pests that can damage their foliage and hinder their growth. In this article, we’ll discuss the most common Fittonia nerve plant pests, how to identify them, and the best treatment methods.

Spider Mites

Spider mites are tiny arachnids that suck the sap out of the leaves of plants, causing them to turn yellow and become speckled with small brown or black dots. They thrive in dry conditions, so keeping your Fittonia nerve plant’s soil moist and humidifying the air can help prevent infestations. If you suspect spider mites are present, wipe down the leaves with a damp cloth and treat the plant with insecticidal soap or neem oil.


Mealybugs are white, fuzzy insects that feed on plant sap and excrete a sticky substance called honeydew. They can cause leaves to wilt and turn yellow or brown. To get rid of mealybugs on your Fittonia nerve plant, isolate it from other plants and spray it with a solution of water and dish soap or neem oil.

Scale Insects

Scale insects are hard, shell-like pests that attach themselves to the stems and leaves of plants. They feed on the sap of the plant and can cause it to weaken and eventually die. Scale insects can be difficult to control because they have a protective covering that makes it hard for insecticides to penetrate. The best way to eliminate them is to scrape them off with a toothbrush or cotton swab dipped in rubbing alcohol.

Fungus Gnats

Fungus gnats are small flies that lay their eggs in moist soil. The larvae feed on the roots of plants, causing them to become weak and stunted. To prevent fungus gnats, allow the soil of your Fittonia nerve plant to dry out slightly between waterings and avoid overwatering. Sticky traps can also be effective in catching adult gnats.


Whiteflies are small, white insects that resemble tiny moths. They feed on the sap of plants and can cause leaves to turn yellow and fall off. To get rid of whiteflies on your Fittonia nerve plant, wipe down the leaves with a damp cloth and treat the plant with insecticidal soap or neem oil.


How often should I check my Fittonia nerve plant for pests?

It’s a good idea to check your plant for pests once a week, especially if you’ve had issues in the past.

Can I use chemical pesticides on my Fittonia nerve plant?

Chemical pesticides can be harmful to your plant, so it’s best to use natural remedies like insecticidal soap or neem oil.

Will repotting my Fittonia nerve plant help prevent pests?

Repotting your plant can help refresh the soil and remove any pests that may be living in it, but it won’t necessarily prevent future infestations. Regularly checking your plant for pests and taking preventive measures is key.

In conclusion, while pests can be a nuisance for Fittonia nerve plant owners, they can be managed effectively with a little know-how and vigilance. By identifying the type of pest present and using natural remedies to treat them, you can keep your plant healthy and vibrant for years to come.
