Drain Fly Larvae (Drain Worms) Control: Identification, Risks & Effective Removal

Drain fly larvae, commonly known as drain worms, are small, translucent or whitish maggots that thrive in damp, organic-rich environments like clogged drains, sewer pipes, and wet under-sink areas.

While harmless to humans, their presence signals underlying moisture issues and potential plumbing problems.
