Mystery Worm-Like Creatures in Houseplant Soil

Identifying Multi-Legged Soil Inhabitants

Tiny, leggy, worm-like creatures appear in soil of new plants, spreading to others.

Fungus gnat larvae: No legs; treat soil with malathion drench.
Caterpillars: Many legs; usually on leaves. Use bait pellets (cover to protect pets).
Earthworms/woodlice: Enter via drainage holes. Dust/spray BHC around base.

Collect specimens in a matchbox for garden center ID. Isolate affected plants outdoors in shade during treatment to prevent spread.
