Clear Worms in Houseplant Soil: Identification and Control

Tiny clear worms on soil surfaces are likely fungus gnat larvae or other soil-dwelling insect larvae. They're generally harmless to plants but indicate moist, organic-rich conditions.

Control Methods

• Dry the soil: Let top 1–2 inches dry completely between waterings. Destroys habitat.
• Soil drench: 1–2 tbsp insecticidal soap per gallon water, or Tabasco/alcohol/soap/water mix.
• Sterilize future soil: Bake at 350°F for 15 minutes in foil, cool before use. Kills eggs/larvae in bagged soil.
• Repot if severe: Replace soil entirely, wash roots gently.

Non-sterile bagged soil or outdoor exposure (screened porch) introduces pests. Always buy "sterilized" potting mix and inspect bags for tears.

These worms don't kill plants—they're a nuisance. Drying the soil usually resolves it.
