These bugs are relentless. After the initial five days, we thought they were gone, but days later they came back with a vengeance. We're going to try to detach the pipes and scrub before starting the 5 day treatment again. The shipment came super fast and we were happy to get started with the product right away.
We have used it every night for about 3 weeks now, and have cut down the flies a lot, but they are still not gone. I'm beginning to think we might have to end up getting an exterminator or something. I have 2 bottles left and will continue to use every night and hope they are gone completely by that time.
I've submitted 2 reviews on this product already because initially after the first week of use the problem seemed to be under control, and I gave the first two reviews 5 stars. Then we went to the once a week treatment and we started seeing a few drain flies again, so now we are back to treating every night and I'm downgrading to 3 stars because we followed the directions exactly and the problem is not "eliminated," although it is better than it was. I noticed in the morning that there is a fly caught in the gel in the sink as though it tried to fly out of the drain and got stuck in the gel that was around the drain hole. There are other flies in the bathroom, and escaping the bathroom as they did before. I'm wondering what else I need to do to eliminate these things. Does anyone have any ideas? Do I need to snake the drain or pour something down there to kill the larvae? What's next? I'm not spending $168 a month to clean out sludge! There has to be a more permanent solution to getting rid of the larva and the breeding ground.
My review right now is a mixed set of emotions. I think it works, but I also have fruit flys and fungus gnats along with these drain flies. Fungus gnats live in the dirt of our house plants. I have treated all of our drains in the house. I bought a 4 pack of this DF 5000 drain fly gel. The only place I am having a "fly" issue now, is my kitchen where I also have the other flys.
I was disappointed in the resuts achieved by the use of the DF 5000 Drain Fly Gel. I treated two sink drains (kitchen and bathroom) per directions for 8 straight days. Applying before retiring to allow maximum treatment time. After four days of treatment the number of flies increased. At the end of the eight days the number decreased to single digits but did not get rid of the flies. It is disappointing that the use of DF 5000 did not eliminate the problem.
