Drain Fly Larva

Found in moist environments rich in organic matter such as sink drains, sewers, septic tanks, and damp soil.

Consumes nutrient-rich slime, algae, bacteria, and decomposing organic material (biofilm) within plumbing.

The larvae live within the gelatinous film of drains; they have a small breathing tube to reach the surface. They pupate near the waterline before emerging as fuzzy, moth-like adults.

Generally harmless to humans and do not bite. They represent a nuisance in homes and can potentially transport bacteria from drains to food surfaces, but they also help break down organic sludge in plumbing.
