Spider Mites on parlor palm
What's Happening
Spider mites (Tetranychus urticae) thrive in the dry air typical of heated indoor environments. Parlor palms are particularly susceptible because their native tropical understory habitat requires 50-60% humidity, while most homes stay below 40%. Mites reproduce rapidly in warm, dry conditions, often going unnoticed until fine webbing appears on leaf undersides.
How to Fix It
- 1
Isolate the plant immediately to prevent spread
- 2
Shower the entire plant with lukewarm water, focusing on leaf undersides to dislodge mites
- 3
Apply neem oil or insecticidal soap weekly for 3-4 weeks, covering all leaf surfaces
- 4
Increase humidity to 50-60% using a humidifier or pebble tray—this alone deters mites
- 5
Inspect weekly with a magnifying glass; look for stippling (tiny yellow dots) on leaves
How to Prevent It
Maintain humidity above 50% year-round. Quarantine new plants for 2-4 weeks. Weekly leaf inspections during dry winter months catch infestations early.
