Fungus Gnat Control: Why Drying Soil Works Best

Target the Larvae, Not the Adults

Adult fungus gnats live ~1 week. Larvae live in top soil layers, feeding on decaying organic matter from overwatering/root rot.

Eradication Steps

1. Remove all loose soil from surface (don't expose roots).
2. Allow soil to dry as deep as plant tolerates before watering.
3. Water just enough to reach that dryness again within a week.
4. No pesticides or soap sprays needed—dryness kills larvae.

Soap Sprays?

For spider mites, not fungus gnats.

Schefflera Rooting

Tip cuttings root in water or damp soil. Thick stems need air-layering (advanced).
