Two-Spotted Spider Mite Infestation

Spider mites thrive in the warm, dry conditions often preferred by Wax Begonias. They pierce plant cells to feed on sap, leaving behind fine silk webbing and causing stippling (tiny white dots) on the leaves.

warning

High Humidity with Low Air Circulation

While Begonias love humidity, stagnant moisture combined with lack of airflow can occasionally trap dust and debris in silk-like patterns from small predatory insects or mite activity.

Common
