Spider Mites on fiddle leaf fig
What's Happening
Spider mites (Tetranychus urticae) are the most common pest attacking Fiddle Leaf Figs, thriving in the dry indoor environments typical of heated homes. These microscopic arachnids feed on leaf undersides, piercing cells and sucking sap, causing stippling that appears as tiny yellow or white dots. Heavy infestations produce fine webbing between leaves and stems. Mites reproduce rapidly in warm, dry conditions (70-80°F with <40% humidity), with populations doubling every 3-5 days. FLFs are particularly susceptible due to their large, thin leaves and preference for bright light (which often means warmer, drier locations).
How to Fix It
- 1
Quarantine plant immediately to prevent spread
- 2
Shower plant thoroughly to dislodge mites and webbing
- 3
Apply insecticidal soap or neem oil every 5-7 days for 3 weeks
- 4
Increase humidity to 60%+ to slow mite reproduction
- 5
For severe infestations: Use miticide containing bifenthrin or abamectin
- 6
Prune heavily infested leaves if more than 30% of plant affected
How to Prevent It
Maintain 50-70% humidity via pebble tray or humidifier. Mist leaves regularly (not a substitute for humidity but helps). Inspect new growth weekly with 10x loupe. Quarantine new plants for 14 days. Increase air circulation without creating drafts.
