What to inspect
Use bright light to inspect leaf undersides and petiole junctions, wipe one area, and compare it again for movement or returning webbing.
Choose one evidence-based action
Isolate the plant, remove mites physically where practical, and follow any labeled product exactly. Repeat inspections across the pest life cycle.
What not to do
Do not diagnose spider mites from one mark, change several major conditions at once, or use an unlabeled treatment. Old damage may remain after the cause is corrected.
Review the outcome
Photograph the same area under similar light, record the date and intervention, then compare the boundary of damage and the quality of new growth. Escalate rapid decline or safety concerns to an appropriate professional.
