These little devils are tenacious and I have had to employ a hard core plan to fight them. I use this product and then try to cover the drain with Borax that I have purchased here and Ajax that i bought at the Dollar Tree. The trick is to give them no where to go!

I definitely don’t want to knock the product because it was well packaged and shipping was fast and efficient. Maybe it just didn’t work for me or I am missing something. It’s a nice and heft supply, there’s no foul odor and it’s easy to use, maybe I don’t have drain flies and they’re a different species. In any case, it just didn’t work. The stickies I purchased on here did work. Good luck.

It’s works ok for small drains but does not perform as advertised.

While fighting a pesky drain gnat / drain fly infestation a few months ago, I had already set out glasses of a apple cider vinegar/water/dish soap solution (covered with punctured cling wrap) near all of our main drains. While they were catching and drowning their fair share of flies, I ordered these reinforcements to completely end the infestation as quickly as possible!In order, I purchased:1. Harris Fruit Fly Drain Treatment Gel (0.5/5)2. Protecker Fruit Fly Traps (1/5)3. AllRoad Window Fly Traps (4/5)4. Dynatrap DT3019-1003P Flylight (5/5)In the hopes of helping those combating a similar infestation decide what to purchase, I will post this complete review+pictures on each product page, with the reviews listed as numbered above.1. Harris Fruit Fly Drain Treatment Gel (0.5/5):This was my first purchase, and second most-expensive only to the Dynatrap light. Now, it's possible that it may 'suffocate' the eggs/larvae in drains, but given its relatively-thin viscosity, I kind of doubt even this (especially if used in drains that will be utilized at all during the treatment period instead of sealed over with cling wrap.) I can say that (other than the aforementioned homemade traps,) I was using this for about a week before getting the other solutions, and noticed no significant effect. As an experiment, I even set out a small cup of the gel, and flies flew into and drowned in it... Then I left the container itself open by my bathroom sink, and the flies just saw another drain to fly into (see picture!)The only reason this even warrants half of a star, in my experience, is that it does smell pleasant.2. Protecker Fruit Fly Traps (1/5, not pictured): I ordered the set of 2. These are literally just cuter, less-stabile versions of the homemade traps I had already set out. They do come with a small vial of what I assume is apple cider vinegar, but certainly not enough to add a substantial amount to the traps, so I just made the normal solution and then distributed the vial contents.I was hoping that the addition of adhesive 'traps' above the liquid trap would catch passersby, but this hope was in vain-- neither adhesive trap caught a single fly! And, compared with their homemade counterparts, these did not catch nearly as many flies (I assume the built-in holes are bored too widely, so the flies could check the liquid out, then easily escape.) I made the mistake of setting one on a ledge in a high-traffic area, and- being the kind of neurodivergent klutz who often bumps into things as I pass by- knocked it over a couple of times, causing it to pop open at the 'seam' and spill the vinegar solution, creating a stinky mess. I don't fault the product for this, but it's worth noting as a possible drawback if you are also cluttered'n'klutzy. Unfortunately I didn't get any pictures before throwing both away as soon as the infestation was over with, but between the two I'd say they caught 10 flies maximum- none on the stickers- so there's not much to show, anyway.3. AllRoad Window Fly Traps (4/5):I received these soon after receiving the Protecker traps, and while the Protecker traps had yet to catch a single fly, these window traps caught several within a couple of hours of installing them on my bathroom window.If you're on a budget and find yourself in this gnat-sy predictament, or if you just want multiple lines of defense like me, these are the way to go. The one drawback is that the 'window cling' line of adhesive is just as strong as the trap side-- and it is *strong.* Removing them did leave adhesive residue on my window, however I did leave them there for a couple of months beyond what was necessary, and a more-conscientious person removing them after a shorter time span may find this to be a non-issue. I'm sure Goo-Gone will take care of it... I'll get around to trying, eventually.4. Dynatrap DT3019-1003P Flylight (5/5):Sure, this is the most pricey solution, but it gets a perfect rating for a few reasons: it is extremely effective, it has no reasonable drawbacks, and it is a device I'll be able to use beyond the infestation I got it for (can't wait 'til porch-sitting weather rolls back around to see how mosquitoes fare against it!)Installation was a snap, and within seconds of plugging it in, I watched a gnat fly right into the adhesive trap. I'm generally a bleeding heart-level animal lover (I even take the odd stinkbug/cricket/spider I find in my house outside and get sad when others smoosh them!) but let me tell you, seeing that gnat fly to its doom filled me with GLEE.In conclusion, I'd totally avoid the first two products unless you're just interested in conducting your own experiment. Instead, I'd recommend making a few homemade traps, and supplementing them with the window stickers and/or Dynatrap light. (Search for a 'recipe' online for the best ratio of water:vinegar:soap in the homemade traps, and don't forget to top them with carefully-punctured cling wrap; this will ensure more flies drown than escape.)

They product did not do much for the drain flies, I reached out to their customer service listed on the bottle and they responded fast and offered me a refund or another gallon, I took them up on another gallon and will try again. Some people complain about the scent being strong but I didn't think it was bad and it was not over powering either.

Takes alot to coat drains

Got it for a fruit fly problem I was having after ida. I put in all sinks and covered the drain as it said. I also used the amount that was said and it didn’t work.
