Drain Fly Larva

Stagnant water, gelatinous film in drains, septic tanks, and sewage areas.

Organic matter, fungi, algae, and bacteria found in drain slime.

The larvae live in the slime layer of drains breathing through a respiratory tube. They undergo pupation within the same organic film before emerging as adult flies.

Generally harmless to humans; they do not bite or sting. However, they can be a nuisance and may transport bacteria from contaminated areas. They benefit the ecosystem by breaking down organic sludge.
