Pot Worm (or White Worm)

Natural Habitat

Moist, organic-rich environments such as soil, compost piles, worm bins, and sometimes excessively wet potting soil in houseplants. They thrive in acidic conditions.

Diet & Feeding

They feed on decaying organic matter, bacteria, fungi, and sometimes dead plant tissue. They are decomposers.

Behavior Patterns

Often found wriggling in clusters in damp soil or compost. They are photophobic (avoid light) and will retreat into soil when exposed to bright light. They reproduce hermaphroditically.

Risks & Benefits

Benefits: They are beneficial decomposers that help aerate soil and break down organic matter into nutrients. Risks: Generally harmless to humans and pets. In high numbers in houseplants, they may indicate overwatering or souring soil, but rarely damage healthy plant roots.
