pest infestation on Rubber Plant
Quick answer
If your Rubber Plant has pest infestation, the most likely cause is: Spider mites (Tetranychus urticae) are tiny arachnids that pierce leaf cells and feed on sap, causing stippling - tiny yellow or brown spots that can coalesce into larger damaged areas. They thrive in dry indoor environments (humidity below 40%) and reproduce rapidly in warm conditions. Webbing on undersides of leaves and stems indicates heavy infestation. Mites are often mistaken for dust until damage becomes severe.
Start here:
- 1. Inspect weekly with magnifying glass, especially leaf undersides
- 2. Isolate infested plant immediately to prevent spread
