Pill Bugs and Fungus Gnats in Your Potted Palm: Drying Out Is the Cure

Identification

• Pill bugs (roly-polies): ½", brown back/tan belly, roll into balls when touched. Not usually destructive, but multiply in constant moisture.
• Fungus gnat larvae: Clear/white, ~¼", distinct black head. Adults = tiny flies above soil.

Unified Solution

1. Let root ball dry out completely. Both pests require constant moisture.
2. Water only when soil dry to knuckle depth.
3. Never let pot sit in saucer water.
4. Potato cubes on soil surface can trap pill bugs for easy removal.

Key Insight

Proper watering (wet-dry cycles) is the most effective, non-chemical management for both.
