How to get rid of spider mites on a money tree? - briefly
Use a vigorous spray of water to knock mites off the foliage, then treat the tree with insecticidal soap or neem oil, repeating every 5–7 days until the infestation clears. Maintain proper humidity and regular leaf cleaning to prevent recurrence.
How to get rid of spider mites on a money tree? - in detail
Spider mites infestations on a money tree develop quickly in warm, dry conditions. Early detection prevents severe leaf damage. Examine the undersides of leaves for tiny moving specks or fine webbing; a white or yellow stippling indicates feeding.
Cultural measures
- Increase ambient humidity to 60 % or higher by misting leaves daily or placing a tray of water near the plant.
- Keep the soil evenly moist but avoid water‑logging.
- Provide bright, indirect light; excessive shade encourages mite reproduction.
- Prune heavily infested branches, discarding them away from healthy foliage.
Mechanical control
- Wash leaves with a strong stream of lukewarm water, focusing on the lower surface, to dislodge mites and webs.
- Use a soft brush or cotton swab dipped in rubbing alcohol (70 %) to wipe individual leaves when infestations are localized.
Biological options
- Introduce predatory mites such as Phytoseiulus persimilis or Neoseiulus californicus; release rates of 10–20 predators per square foot are effective.
- Apply neem oil at 0.5 % concentration, sprayed thoroughly on both leaf surfaces every 7–10 days, pausing for two weeks before any flowering period.
Chemical treatments
- Select a horticultural acaricide labeled for indoor use, containing abamectin or bifenthrin.
- Follow label dosage precisely; apply in the early morning or late afternoon to reduce plant stress.
- Rotate products with different modes of action to prevent resistance buildup.
After any intervention, monitor the plant for two weeks. If mite numbers decline, continue a maintenance spray of neem oil or a mild soap solution (1 % castile soap) every 14 days for one month to ensure complete eradication. Maintain proper humidity and airflow to keep future outbreaks at bay.
