Drain Fly

Natural Habitat

Drain flies are commonly found in bathrooms, kitchens, and basements, particularly in drains, sewers, septic tanks, and areas with standing water and decaying organic material.

Diet & Feeding

Larvae feed on decaying organic matter and microbial films found in drains, sewers, and soil. Adult flies feed on liquids and possibly nectar.

Behavior Patterns

These small flies are often seen buzzing around drains, garbage cans, and other damp, organic-rich areas. They have a distinctive jerky flight pattern. Adults are weak fliers and tend to stay close to breeding sites.

Risks & Benefits

Drain flies are generally considered pests rather than a significant risk to human health. They do not bite or transmit diseases. Their presence can indicate issues with plumbing or decaying organic matter.
