Most Common Chinese Coin Plant Pests:
Identification and Treatment Guide

Chinese coin plants are popular houseplants known for their distinctive, round leaves that resemble coins. While they are generally easy to care for, Chinese coin plants can fall prey to a variety of pests. Recognizing these pests and knowing how to treat them is essential to keeping your plant healthy.

Identification of Common Chinese Coin Plant Pests

Here are some of the most common pests that can affect Chinese coin plants:

Mealybugs

Mealybugs are small, white insects that feed on plant sap. They can be found in clusters on the stems, leaves, and flowers of Chinese coin plants. Mealybugs secrete a sticky substance called honeydew that attracts ants and can lead to the growth of black sooty mold.

Spider Mites

Spider mites are tiny, spider-like creatures that feed on plant sap. They often appear as tiny red or brown dots on the leaves of Chinese coin plants. Infested leaves may also become discolored and have a web-like appearance.

Scale Insects

Scale insects are small, oval-shaped insects that attach themselves to the stems and leaves of Chinese coin plants. They can be identified by their hard, shell-like covering. Scale insects feed on plant sap and can cause yellowing and wilting of leaves.

Fungus Gnats

Fungus gnats are small, dark-colored flies that lay their eggs in moist soil. The larvae feed on the roots of Chinese coin plants, which can cause stunted growth and yellowing of leaves.
