What should be done if white mites appear on an orchid? - briefly
Isolate the orchid, gently rinse leaves with a mild soap solution, and remove visible mites. Apply a suitable miticide—such as neem oil, horticultural oil, or a systemic acaricide—and repeat the treatment weekly until the infestation is eliminated.
What should be done if white mites appear on an orchid? - in detail
White mites on orchids indicate a pest problem that requires immediate intervention. The first step is isolation: move the affected plant away from healthy specimens to prevent spread. Next, inspect the foliage and roots closely, using a magnifying lens if necessary, to determine the severity of infestation.
- Mechanical removal – gently wipe leaves with a soft, damp cloth or cotton swab to dislodge visible mites. Rinse the plant with lukewarm water, allowing excess moisture to drain.
- Chemical control – apply an appropriate miticide labeled for use on orchids. Follow the manufacturer’s dosage instructions precisely; repeat treatment after seven days to target emerging generations.
- Biological options – introduce predatory insects such as Phytoseiulus persimilis or Neoseiulus californicus, which feed on white mites. Ensure the environment remains suitable for these agents (temperature 20‑25 °C, humidity 60‑70 %).
- Cultural measures – increase air circulation around the plant, reduce excessive humidity, and avoid over‑fertilization, all of which create unfavorable conditions for mite reproduction.
After treatment, monitor the orchid daily for at least three weeks. If any mites reappear, repeat the chosen control method. Finally, maintain a regular sanitation schedule: clean pots, trays, and tools, and quarantine new acquisitions before introducing them to the collection. This comprehensive approach eliminates the infestation and protects the orchid’s long‑term health.
