Drain Fly Treatment NYC
Drain flies (moth flies) breed in the organic buildup inside drains, pipes, and sewage systems. They're extremely common in NYC apartments, restaurants, and commercial kitchens. While harmless, they multiply rapidly and indicate plumbing maintenance issues. Treatment requires identifying and cleaning breeding sites, not just killing adults.

Drain Fly Treatment — Frequently Asked Questions
Common questions our licensed exterminators receive about drain fly treatment in New York City, including costs, treatment timelines, preparation steps, and what results to expect.
How much does drain fly treatment cost?
Drain Fly Treatment starts at $49, fully inclusive. The price covers all labor, EPA-registered products, treatment methods, entry-point sealing, written plan, and the free re-treatment visit if pests come back. There are no per-room fees, no chemical surcharges, no trip fees, and no contract. You pay only on completion of the work — nothing upfront, no deposit, no card on file. Final pricing is quoted upfront after a free inspection and depends on the size of your specific job — transparent, with no worst-case markup.
What are drain flies?
Drain flies are small (1/8 inch), fuzzy, moth-like flies that breed in the organic slime inside drains. They're often seen hovering near bathroom and kitchen sinks, shower drains, and floor drains, especially in the morning.
Why do I keep getting drain flies?
Drain flies breed in the biofilm (organic buildup) inside pipes. Simply killing adult flies won't solve the problem — the breeding site must be cleaned. Drains that aren't used regularly are especially prone to buildup.
Can I get rid of drain flies with bleach?
Bleach provides temporary relief but doesn't eliminate the organic buildup where drain flies breed. Professional bio-enzyme treatments break down the biofilm that drain flies need to reproduce, providing lasting results.
Are drain flies common in NYC restaurants?
Very common. Floor drains, bar drains, and grease traps in NYC restaurants provide ideal breeding conditions. Regular drain maintenance and bio-enzyme treatments prevent drain fly issues and help with DOH compliance.
