Why Harrison Has a Drain Flies Problem

Harrison's beautiful tree-lined streets, historic homes near the Rye Lake area, and bustling commercial properties along Harrison Avenue all face drain fly challenges, especially in older buildings with aging plumbing systems. From downtown Harrison to the Purchase area, our team knows the local architecture and drainage issues that can lead to drain fly problems.

Why Choose Us for Drain Fly Treatment in Harrison

Drain flies breed exclusively in the organic slime layer that builds up on the inner walls of drains, pipes, and any moist organic material — and they cannot be eliminated without removing their breeding medium. Our treatment applies a professional biological drain gel (enzyme-based) to all floor drains, sink drains, and any standing water areas where organic matter accumulates, breaking down the breeding substrate over 7–10 days while adult populations are treated with a quick-knockdown product. We inspect all potential breeding sites including basement floor drains, bar drains, mop sink areas, and HVAC condensate lines — anywhere organic matter and moisture meet. Our 30-day guarantee covers re-treatment if drain fly populations return within a month of completed treatment.
