Drain Gel American Bio-Systems Drain Flies

Works exactly as advertised. Watch the video to see how to apply. We had drain flies in the bathroom coming from a bathtub that isn’t used. I first tried salt, baking soda and vinegar which is a widely recommended trick. It was a temporary fix that worked only for a few days. The drain gel got rid of all flies by the third day of the 5 day application. It’s been a month and zero issues. We will definitely use this going forward. I was concerned the gel may smell, but it is odorless...huge plus!

If you ever get tons of gnats flying around, it's probably a nest in your drain. Using this stuff kills the nest or junk which attracts them in the first place. Then all you have to do is kill the gnats by sitting out plastic bottles with holes punched near the top but not the cap. Add apple cider vinegar to the bottle, put the cap on. Then watch the gnats get in, can't get out and die.

This product does clean the scum off the drain inner walls. What Drain Flees live on. Would be much better if an Insecticide were added into this Drain Gel. It does not kill the tiny pest. Besides the kitchen sink I use it in the upper vents or overflows of my bathroom sinks. You will still need Flying Insect Spray.

Use this and then also take an electric fly swater to any remaining Flys you see. They'll be gone in 2 days. Little goes a long way but make sure you coat the sink God by going in a circular motion when pouring. Leave overnight before washing down with hot water.

The product helps for a day or two then the drain flies returned. I'm going to have a plumber clean the pipes.

I was not sure if this blue goo would work, but it worked for me. we were gone on vacation for 9 days and followed the instructions. we also covered the drains after the treatment. when we got home...No drain flies! I recommend this product

I followed the instruction to the letter...used nightly until the bottle was empty...drain flies still persist...The search continues.

Easy to use and works as promised. Got rid of the gnats we had in the kitchen drain
