Spider Mites on Desk Cactus: Non-Chemical Control for Office Settings

Confirm It's Spider Mites

• Fine webbing (not dense cottony = mealybugs).
• Stippled, dusty-looking epidermis.
• Tap over white paper: tiny moving specks.

Office-Friendly Treatment

1. Take plant outside or to sink.
2. Spray forcefully with water (shower/sprayer) to dislodge mites.
3. Wipe stems with damp cloth.
4. Apply insecticidal soap or neem oil (low odor) per label.
5. Repeat weekly ×3.
6. Increase humidity (pebble tray); mites hate moisture.

Prevention

• Quarantine new plants 2 weeks.
• Regularly mist/wipe foliage.
• Avoid hot, dry drafts (heater vents).

Avoid systemic pesticides in occupied offices—unnecessary exposure risk.
