A waste of money
I’ve had phlorid flies in my home for a couple weeks but I can’t find any source for them. I tried invade bio drain but it had absolutely no effect on my infestation. I poured an entire bottle down the drain but I was just pouring my money down the drain. This product is useless for this problem.

The Only product that worked.
I had a very bad case of Phorid flies. I tried everything, I even signed a contract with a local pest control company. They treated my drains with Bio Drain treatment. In a couple of days there was a marked improvement. Then after a week some flies returned. I canceled the contract because they didn’t want to treat often enough. I bought a gallon and did it myself. This time 4-5 days apart. After 2 more treatments the flies were gone.
I wish I had discovered Bio Drain on my own. I could have saved $255.

Worked Great!
We bought a gallon, used it on 5 different drains for a week and no more drain flies - will likely buy another drain to use once a month for maintenance - thank you!

Followed the directions and FINALLY NO MORE FRUIT FLIES. I also used Invade hot spot along with the Bio Drain! Worth every penny!

so far so good
so far so good with this product. we have been fighting drain flies since we bought our house a couple years ago. have tried the vinegar with baking soda thing, will work for awhile but they come back. I have been randomly using this product and have not seen any. did not give five stars because it has been too soon to tell if they will come back, but fingers crossed.

OK-but not perfect so far...
Sorry I can't write a perfect review at this time; used the product exactly as directed...it has "knocked" back the majority of the black drain flies, but has not completely obliterated them. Still find 1 to several each day in the master bathroom. Will continue to use product as directed for the time being and hope for better results. I am at my wits end!!!

It works if you use a lot
We slowly realized we had a drain fly problem. I had never even heard of them before, but all of a sudden there were several hanging around the house. They're really easy to snack dead since they don't seem to have the same reflexes as regular house flies. But, they wouldn't stop coming. Where are these things coming from? Then we saw them circling the drain in the back of the basement. Ah hah! So I poured a bunch of bleach down the drain
That should take care of it. NOT. So then we looked it up and learned that not much can get rid of them. That brought us here. So I bought a bottle of this stuff thinking it was a bit expensive, but nothing else seems to work so let's give it a try. I poured about a half a cup down the drain and waited. Well, that didn't seem to do anything because the flies kept coming. I could look down into the drain and see the liquid down there kind of writhing around. Yech. So I figure this was a waste of money anyway, let's see if more works. There was a little over half the bottle left after I had poured some down all the other drains in the house. So I poured the rest, over half the bottle, down the drain. Boom. It worked. The water stopped writhing (with maggots) and the flies stopped coming. We haven't had a fly yet and it's been a few weeks now. So while it's a bit expensive, it worked better than straight bleach to kill these flies and their larvae. I suggest you use way more than the directions say. The directions are for regular drain cleaning, not for killing drain flies.
