Eliminating Fungus Gnats in Pothos Soil

Fungus Gnats = Overwatering

Those tiny flies are fungus gnats breeding in constantly moist soil. The fix is cultural, not chemical:

Action Plan

1. Dry out thoroughly: Water only when soil feels dry and pot feels light.
2. Alcohol drench: Water once with straight rubbing alcohol to kill larvae (won't harm roots).
3. Improve drainage: Repot with 50% perlite added to potting mix.
4. Empty saucers within 2 hours of watering.

Consistent drying between waterings prevents recurrence.
