Spider mites or other sap-sucking pests
Sticky residue, faint webbing, or speckled, dull leaves point to spider mites or a similar sap-sucker.
Diagnosis
Spider mites or other sap-sucking pests
What's happening
When the leaves feel sticky or look dull and speckled with tiny pale dots — sometimes with fine webbing on the undersides or at the stem tips — sap-sucking pests like spider mites are feeding on the plant. They thrive in warm, dry air and multiply fast, draining the leaves and leaving them stippled, faded, and weak.
How to fix it
Isolate the plant, then rinse it under a gentle stream of lukewarm water to knock off as many pests as possible, paying special attention to the undersides of the leaves. Follow up by treating the whole plant thoroughly with neem oil, coating both sides of the foliage and the stems. Repeat every 5–7 days for a few weeks to break the breeding cycle, and raise the humidity a little, since mites favor dry air.
What fixes it
- Neem oil for pests — Neem oil disrupts the pests' life cycle and keeps them from re-infesting once you've rinsed the worst off.
If that doesn't fix it
This is general guidance based on common symptoms; individual plants vary.
