Spider mites often cause pale stippling, a dull appearance, and, as populations rise, fine webbing between leaves and stems. Recovery means isolating the plant, confirming the pest, reducing the population, and repeating checks because eggs and mites can remain hidden. A badly stressed plant also needs heat, dryness, or watering problems corrected.
Isolate the plant and inspect leaf undersides in good light
Look for tiny moving dots, eggs, and fine webbing, especially under leaves. A white sheet of paper beneath the plant can make dislodged mites easier to see after a gentle tap. Do not treat every plant by assumption; inspect nearby plants first.
Reduce the population with water and selective pruning
For species that tolerate wet foliage, a gentle shower can dislodge many mites, especially from undersides. Remove badly damaged leaves without stripping the plant bare and clean the immediate area. Avoid strong jets that break stems or scatter potting mix.
If treatment is needed, cover thoroughly and repeat as labeled
Insecticidal soaps or horticultural oils labeled for that plant can work by contact, but they must reach undersides and hiding places. Test a small area first and follow label intervals, temperature limits, and rates; more product does not mean better control.
Watch new growth before returning the plant to the group
Check every few days for several weeks and look for new growth without stippling or webbing. Keep watering appropriate and avoid excessive heat or dryness. If the infestation persists despite repeated control, discarding a severely affected plant may be more practical for protecting the rest.
