  • Drain Gel Fly Killer
    By Robin Freel on 6/28/2013
    I am a professional exterminator and have been using this product for years with great results.


  • Drain Gel Fly Killer
    By Tina Gaddy on 4/27/2010
    I purchased 2 bottles of the drain gel. It did help slow down the drain flies but unfortunately, we are still having a problem. We just discovered that the problem might be the floor drain in the garage that is next to the hot water tank. So, we are ordering more to use for this drain as well. We have definitely seen a decrease in the amount of flies so I know the product is working!! Will be ordering more. Thank you!

    By Eric Peterson on 1/6/2010
    We noticed a few fruit flies(gnats) flying around our kitchen and assumed that it was from the bananas on the counter. We got rid of the bananas but the flies did not go away, they got worse and we started to see them in our bathrooms as well. We could not get rid of them no matter what we did and i was ready to call an exterminator. My sister was over one day and said that she had the same problem and called an exterminator and he poured Drain Gel down all the sinks in house and told them to use it for 4 or 5 nights in a row. I searched for Drain Gel online and found it at and ordered it right away. It worked GREAT and I am so happy that I found this website as I will be back whenever I have any pest control issues in the future. I am going to order another bottle to have on hand in case they ever decide to show up again.
