Kill Them Where They Actually Breed

Sprays and traps only kill the adult flies buzzing around your sink. The real problem is the slimy film of organic gunk lining your pipes — that's the nursery where eggs and larvae live. DrainVanish foams down into it and wipes out the breeding ground itself, so new flies stop hatching.

Two Scoops. A Little Water. Done.

No plumber, no harsh chemicals, no guesswork. Drop two scoops into the drain, add a little water, and the fast-acting powder erupts into a thick foam that expands through the pipe and trap. It clings to every surface the flies use to breed, then rinses clean.

One Jar For Every Drain In The House

Kitchen sink, bathroom sink, shower, tub, garbage disposal, floor drains — anywhere drain flies breed, DrainVanish works. It's septic-safe and free of caustic chemicals, so you can treat the whole house on a schedule and keep the flies from ever coming back.

Frequently Asked Questions

check_box

Does it really kill drain flies for good?

Yes — as long as you treat the source. DrainVanish foams deep into the pipe and trap where the eggs and larvae live, so new flies stop hatching. Heavy infestations may need a second treatment a few days later.

How do I use it?

Add two scoops of powder to the drain, then pour in a little water. It erupts into a thick foam that coats the inside of the pipe. Leave it to work — ideally overnight — then run the tap. The scoop is included.

Is it safe for septic systems and pipes?

Absolutely. DrainVanish is septic-safe and free of caustic chemicals, so it won't damage your pipes, tank or the good bacteria your system needs.
