Seems to be the easy fix!
We've had recurring invasions of phorid flies since last summer, originating from a neighboring dumpster abutting our back fence and back doors. So we quit using those doors, but the problem - and the flies! - kept coming back, as they were by then breeding inside and not just flying in. It's now been about a month and this stuff seems to have done the job. After repeat visits from a pest control company with no permanent fix (altho they SAID they had one - WRONG!), the Invade Bio Drain gel seems be the easy fix to that now-no-longer-occurring problem!

Impressive outcome!
I had a gnat/flie problem, along with some bad odors that came from my bathroom drains. I found Bio Drain and ordered it. I had a delivery issue, someone took my stuff. This company promptly re-sent it, at no cost, thank you so much. The results of using this product has eliminated the odor problem and I dont have anymore gnats/flies either. Impressive. I highly reccommend Bio Drain and I rarely have a recommendation like that. Worth every penny.

Got the job done, PERIOD!
I moved into a new home, immediately started to notice drain flies, I thought it was my homes septic tank so I had it emptied. That didn't solve the issue, so I went online to learn about these "harmless" flies (only harmless if they are not invading your home) which I felt was happening. I wound up on this website and watched the tutorial by these 2 guys, the tutorial video made me feel like these guys new what they were talking about. So I made a purchase of 5 gallons of this product. I wasn't 100% sure where the flies were coming from so I wasn't going to risk it. I followed the instructions and then some in every point of entry........2 weeks later, I feel like I live in a completely different home, as if these flies never existed. It works! don't second guess it, the two guys new what they were talking about recommending this product.

Fantastic product
Great product, this stuff really works. Had a drain fly problem on a 15 yr old boat, some of the drain pipes even used to clog up. It did take a couple of days with daily treatment of all 20 sinks and showers to kill the drain flies, but they are completely gone now. I use it once a week to maintain clean drains, and surprisingly one drain pipe that we had to take apart and clean every 6 months is completely clean!!! Seriously this stuff really works, and it smells great too! Just be sure to wipe up any spills immediately as it will stain.

Bummer I think its a winter must
old apartment....VERY,Very cold.

Do I want to rinse to the garbage disposal or throw out in garbage and carry outside more often to dumpster . Until it gets warmer I will use this to maintain the garbage disposal and go outside less often

I ordered Invade Biodrain with Outbreak Defender for fruit fly like flying insects that appeared heavy out some where?. Outbreak defender helped me get rid of all the flying insects that where alive when i got it (within 3 days)then BioDrain prevented new ones..So after 10 days I have no more of those flies. I think they were coming from my drains. I think it was because I like yogart every morning for breakfast. After i scoop out a serving I just rinse the bowl for breakfast again the next day.After a few years that pattern must have provided a place for the flies to lay their eggs.. I posted an even more enthusiastic review under Outbreak Defender. It was both product that fixed the problem for me and I thank DIY for their response to my emailed question when i was so afraid i would never get rid of them. Thanks, Lynn

Trial and error
This worked well to clean the drains. It turned out I did not have drain flies though. After attacking and trapping the flies, I figured out they were gnats. I had transplanted a potted plant and soil I purchased apparently had some type of gnat eggs in it. Ended up treating soil with insecticide and putting a top layer of small rocks/gravel. Gnats immediately gone next day. My drains are super clean now though!

So far, it's doing a great job keeping our drains free of flies.

It Works
This product works as it says it will. It smells great, is easy to use and lasts a long time. The cost is reasonable for the amount you get, too. I will continue to purchase this product when needed.
