How the bundle works

  1. 1

    Foam the drain and disposal

    Drain Fly Killer's expanding foam coats the inside of the disposal housing and the pipe below it — the spots you can't reach and where flies actually breed. 4 treatments, 16 doses per pack.

  2. 2

    Clean out the disposal

    One scoop of Garbage Disposal Cleaner super-activates the bacteria already in there, multiplying their appetite up to 40x so they eat through the food waste caked under the blades and in the splash guard.

  3. 3

    Keep it fresh monthly

    A scoop a month keeps the disposal clean, the odor gone and the flies with nowhere to lay eggs. 30 treatments in the bag.

Questions before you buy

Why does my kitchen sink smell even after I run the disposal?

Running it grinds the food but doesn't remove what's stuck to the housing, the underside of the splash guard and the pipe wall. That residue is what rots and smells — and it's what drain flies feed and breed on. The disposal cleaner digests it; the foam handles anything living in there.

Will the disposal cleaner damage my unit?

No. It's a non-toxic powder, not a caustic chemical. It works by boosting the bacteria already present rather than burning material away, which also means it won't corrode the grinding components — Dr. Pooper's claim is that it extends the life of the unit.

How fast will the flies be gone?

Most adults die off within a day or two of the first foam treatment. Eggs already laid can still hatch during the first week, so keep up the monthly maintenance rather than judging it on day three.

Is it safe for septic and older plumbing?

Yes, both are. No pesticides, no caustic chemicals. The disposal cleaner is built on the same bio-accelerator formula as Dr. Pooper's septic products, so it helps a septic system rather than harming it.

What if it doesn't work for me?

Email us within 30 days of delivery and we'll refund you. You don't have to ship anything back, and there's no restocking fee.

Try it for 30 days. Risk-free.

If the flies aren't gone and the sink still smells, email us and we'll refund you. Simple as that.
