Fungus Gnat Larvae in Houseplants: Overwatering Is the Real Problem

Those tiny white "maggots" in your soil are fungus gnat larvae eating rotted roots. The gnats aren't the problem—your watering is.

The Cycle

• Overwatering → roots rot → fungus grows on dead roots
• Fungus gnats lay eggs in fungus-rich soil
• Larvae eat fungus AND rotting roots
• Adults emerge → you see "fruit fly" clouds

Yucca-Specific

Yuccas are DESERT plants. Water ONLY after 3+ dry days. Your yucca lost all leaves and pulled out rootless because roots rotted completely.

Universal Fix for All Plants

1. Empty ALL drain trays
2. Let plants dry out thoroughly (pot feels light)
3. Next watering: 50/50 water + rubbing alcohol (kills larvae in soil)
4. Going forward: water only when dry + light

Prevention Mindset

Most houseplants die from TOO MUCH water, not too little. "Water on schedule" kills. "Water by feel" saves lives.

Your plants will recover once the swamp conditions end.
