Drain Fly Larva
Psychodidae (family)

- Order: Diptera; Family: Psychodidae
- Size
- 4 to 10 mm in length
Natural Habitat
Found in moist environments rich in organic matter, such as bathroom drains, septic tanks, and sewer pipes.
Diet & Feeding
Consumes the organic slime (biofilm), fungi, and bacteria that accumulate inside drain pipes and wet crevices.
Behavior Patterns
The larvae live within gelatinous films in drains; after finishing their larval stage, they pupate and emerge as small, fuzzy adult flies often called moth flies.
Risks & Benefits
They do not bite or sting and are generally harmless to humans, but their presence can indicate a build-up of organic waste or standing water that needs cleaning.
