Drain Fly

Damp environments rich in organic matter such as bathroom drains, kitchen sinks, sewers, and septic tanks.

Larvae feed on the nutrient-rich slime (biofilm) that forms in drains; adults primarily consume liquids like nectar or polluted water.

Poor fliers that often crawl on walls near drains. They are most active at night and have a life cycle of about 2 to 3 weeks.

Generally harmless as they do not bite or transmit diseases, but large infestations act as a nuisance and can indicate plumbing issues or poor hygiene.
