Eliminating Fungus Gnats from a Queen Anne Fern

Small flies/gnats appeared around a Queen Anne fern overwintering indoors, but not on the plant itself.

Source: Soil, Not Foliage

Fungus gnats breed in overly wet soil where roots are rotting.

Fix

1. Water once with rubbing alcohol (same volume as normal watering) to kill larvae.
2. Let soil dry thoroughly; then keep on the dry side (water less, empty tray).
3. Increase humidity via misting 2× daily and pans of water on registers.
4. Place in bright east window for morning light.
