Common Calathea Medallion Plant Pests

Spider Mites

Spider mites are tiny pests that feed on the sap of plants, leaving behind tiny yellow spots on the leaves. They thrive in warm and dry conditions and reproduce rapidly. Spider mites are difficult to see with the naked eye, but you can spot their webs on the undersides of leaves.

Mealybugs

Mealybugs are small white insects that look like cotton balls. They feed on the sap of plants and can cause leaf drop, stunted growth, and even death. Mealybugs multiply quickly, so it’s essential to identify and treat them as soon as possible.

Scale Insects

Scale insects are small, oval-shaped insects that attach themselves to the stems and leaves of plants. They suck sap from the plant, causing yellowing and wilting of leaves. Scale insects secrete a sticky substance that attracts ants and can also lead to fungal growth.
