How can I eradicate spider mites at home? - briefly
Use a vigorous water spray to knock mites off plant surfaces, then treat foliage with neem oil or insecticidal soap every 5–7 days, covering both upper and lower leaf sides. Remove severely damaged leaves and maintain low humidity to discourage further infestations.
How can I eradicate spider mites at home? - in detail
Spider mites thrive in dry, warm conditions and can quickly damage indoor plants. Effective eradication requires a combination of cultural, mechanical, and chemical strategies.
Start by isolating affected specimens. Place them away from healthy foliage to prevent spread. Trim heavily infested leaves, discarding them in a sealed bag. Clean the growing area with a solution of water and mild detergent, then rinse thoroughly.
Increase humidity levels, as mites prefer dry air. Use a humidifier or mist the plants several times daily until a thin film of moisture covers the leaves. Maintain temperatures between 65‑75 °F (18‑24 °C) to discourage reproduction.
Apply direct contact treatments:
- Insecticidal soap – spray until runoff covers both upper and lower leaf surfaces. Repeat every 5–7 days for three applications.
- Neem oil – mix according to label instructions, apply similarly to soap. Provides both repellence and growth disruption.
- Horticultural oil – use a fine‑mist application, ensuring full coverage. Reapply after rain or watering.
For severe infestations, introduce biological controls:
- Predatory mites (e.g., Phytoseiulus persimilis) – release according to package guidelines; they consume spider mites and reproduce on the host plant.
- Entomopathogenic fungi (e.g., Beauveria bassiana) – apply as a spray; fungi infect and kill mites without harming plants.
Mechanical removal can supplement chemical measures:
- Wipe leaf undersides with a damp cloth or cotton swab to physically dislodge mites.
- Use a strong jet of water to flush insects from foliage, directing runoff away from the plant base.
Monitor progress by inspecting leaves every two days. Continue treatments until no mites are observed for at least two weeks. After eradication, implement preventive practices: keep humidity above 50 %, avoid excessive nitrogen fertilization, and regularly inspect new plants before introduction.
