Drain Fly Larvae

Moist, decaying organic matter, typically found in drains, sewers, septic tanks, and other areas with stagnant water and sludge buildup.

Feeds on fungi, bacteria, algae, and decaying organic matter found in the sludge and biofilm of their aquatic or semi-aquatic habitats.

The larvae of drain flies are aquatic or semi-aquatic and are often found wriggling in the slimy buildup inside drains. They have a distinct segmented body. The adult flies are small, fuzzy, and moth-like, often seen emerging from drains.

Potential risks include being a nuisance pest indoors. While generally not known to transmit diseases, large infestations can be unhygienic. They also indicate a buildup of organic material in pipes which can lead to clogs if not addressed. They provide some benefit in breaking down organic matter.
