Worms in Houseplant Soil: Fungus Gnats or Larvae?

Small worms in potting soil are usually fungus gnat larvae, centipedes, or millipedes—all thrive in constantly wet soil.

Fix the Root Cause

• Water by weight: soak, drain, wait until pot feels light.
• Allow soil to dry deeply between waterings.
• Use sterile, peat‑perlite mixes (avoid Miracle‑Gro).

Direct Treatment

1. Apply a safer‑soap soil drench per label.
2. Repeat in 14 days if needed.
3. Bring a specimen to a local nursery for exact ID.

Dry soil breaks the life cycle.
