  • I was embarrassed having guests over because of the tiny flies around our sink. After treating the drain, the problem disappeared and hasn't returned

  • I tried sprays, traps, and boiling water, but the flies always came back. After using Avenor Drain Defense, they gradually disappeared and haven't returned.

    How do I use it?

    Using Avenor Drain Defense is quick and simple:

    Step 1: Identify the drain where drain flies are present.

    Step 2: Apply the recommended amount of Avenor Drain Defense directly into the affected drain.

    Step 3: Allow the treatment to work inside the drain and target hidden breeding areas.

    Step 4: Repeat treatments as directed to help break the drain fly life cycle.

    Step 5: Continue using until drain fly activity has stopped and maintain as needed for ongoing protection.

    Pro Tip: For best results, treat all nearby drains where drain flies may be breeding, including sinks, tubs, showers, and garbage disposals.
