Drain Fly Treatment in Williamsburg, Brooklyn

Drain flies are small (1/8 inch), dark, moth-like insects often seen resting on bathroom or kitchen walls near sinks, showers, or floor drains. They have a fuzzy appearance and fly in short, jerky patterns. If you notice several of these insects around drains or damp areas, you likely have an infestation in your plumbing.

Our drain fly treatment includes a thorough inspection to locate breeding sites, mechanical cleaning or foaming of affected drains to remove organic buildup, application of targeted bio-enzymatic or approved insecticides, and follow-up recommendations to prevent future infestations. We address all potential breeding areas including floor drains, sink drains, and any moisture-prone locations.

Most drain fly infestations can be controlled within 1-2 weeks after initial treatment. However, because drain flies have a rapid breeding cycle, you may continue to see adult flies for 5-7 days after treatment as eggs hatch. Complete elimination typically requires addressing the source of organic buildup and may include a follow-up visit to ensure all breeding sites are treated.

The cost depends on several factors including property size, number of drains requiring treatment, severity of the infestation, and accessibility of breeding sites. A small studio apartment with one affected drain will be at the lower end, while larger multi-bathroom homes, restaurants, or properties with extensive plumbing systems will be toward the higher end of the range.
