Drain Fly (Psychodid fly)

Damp areas around drains, pipes, bathrooms, kitchens, and sewage facilities

Larvae feed on organic sludge, algae, and bacteria in drains; adults feed on liquid nectar or polluted water

Weak flyers that move in short, jerky hops; nocturnal and attracted to light; females lay eggs in organic gelatinous film inside drains

Harmless to humans as they do not bite or sting; can become a nuisance pest indoors; larvae help break down organic debris in sewage and drains
