Drain Fly Larva

Damp environments rich in decaying organic matter, such as drains, sewage pipes, septic tanks, and wet compost.

Feeds on the slimy film of bacteria, fungi, and organic debris found in drains and moist areas.

The larvae live within gelatinous films in drains; as adults, they are weak fliers and often stay close to their breeding source. They undergo complete metamorphosis.

They are considered a nuisance pest but do not bite or transmit serious diseases. Their presence can indicate a plumbing leak or buildup of organic matter that needs cleaning.
