Drain Gel American Bio-Systems Drain Flies

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.

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 is to get rid of fruit flies, but it apparently was not sealed (maybe a past returned bottle because the inside seal on the bottle wasn’t there) anyway it leaked inside the box, but it’s so thick that it had not leaked through the box so there was no way for the delivery driver to be made aware that the product was leaking

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!

I was looking for a product with little to no odor because I am very sensitive. This one is too strong for me to use.

After the prescribed treatments my drain flys we're no more. Amazing.

This is a liquid, not a thick gel like other similar products. I used this for three nights for drain flies and it made no difference.

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