How can a spathiphyllum be cured of spider mite? - briefly
Isolate the plant, rinse the leaves thoroughly with a strong water spray to dislodge mites, then apply a 1–2 % neem‑oil or insecticidal‑soap solution to all foliage (including undersides) and repeat the treatment every 5–7 days until mites disappear.
How can a spathiphyllum be cured of spider mite? - in detail
Spider mite infestations damage spathiphyllum leaves by extracting sap and causing stippling, yellowing, and webbing. Immediate action prevents spread to nearby plants.
Inspection and isolation
- Examine each leaf, focusing on the undersides, for tiny moving specks and fine silk threads.
- Separate the affected specimen from other houseplants, placing it in a well‑ventilated area away from other foliage.
Mechanical removal
- Rinse the plant with lukewarm water from a gentle shower, allowing water to flow over both leaf surfaces.
- Use a soft brush or cotton swab dipped in water to dislodge mites from dense clusters.
- Repeat the rinse every 2–3 days for two weeks.
Chemical or organic treatments
- Dilute horticultural oil (e.g., neem or mineral oil) to 1–2 % v/v with water; spray until runoff covers all leaf surfaces, especially the undersides.
- For synthetic options, apply a miticide labeled for indoor use (e.g., abamectin) at the manufacturer‑recommended concentration.
- Maintain a 7‑day interval between applications; do not exceed the maximum number of treatments listed on the product label.
Environmental adjustments
- Increase ambient humidity to 60 % or higher using a pebble tray or humidifier; high humidity reduces mite reproduction.
- Keep temperature between 20–25 °C; extreme heat or cold stresses the plant and may worsen the infestation.
- Ensure adequate air circulation without creating drafts that dry foliage.
Monitoring and follow‑up
- Inspect the plant weekly for new signs of activity.
- Continue low‑dose oil sprays for an additional 3–4 weeks after visible mites disappear to interrupt any residual life cycle.
- Remove any fallen leaves or debris that could harbor eggs.
Preventive practices
- Quarantine new acquisitions for at least two weeks before introducing them to the collection.
- Clean pots and trays regularly with mild soap solution.
- Avoid over‑fertilizing, as excessive nitrogen promotes soft growth favored by mites.
By combining thorough washing, targeted spray treatments, and controlled environmental conditions, a spathiphyllum can be cleared of spider mites and kept healthy over the long term.
