InVade Bio Drain 1 Gallon (Original Version)

Second time I use Bio Drain, works like a charm! Cleans and gets rid of flys that multiply in the gunk! There’s nothing so frustrating than to have flys come out of the drain 🙄

This works. It cleans drains, smells good, and drains flow much faster.

Once a year I use a gallon in the sink and shower drains to prevent build up. Seems to work well and has a pleasant smell.

After trying the diy boiling water and baking soda with vinegar method and also a different brand of bio drain treatment from home depot, this is the only thing that worked for my drain fly problem... and I truly wish I would've just started with this to save time and money. The gel consistency definitely coats the drains vs some of the cheaper alternatives which are truly liquid and didn't work at all. Wish it was a little cheaper since I have 8 drains to cover and each drain took 1/2 a cup per treatment, every other day for a week but, the effectiveness is worth every penny. I stopped seeing drain flies come out of the drains within the first 2 days, despite the stragglers that were already out and in the house. After pouring the treatment down each drain at night, I covered the drain opening with a paper cup just to prevent any from flying out. Although I stopped seeing the flies after the first 2 days, when the 1 week treatment period was over, juuussttt to be sure, once a week for a month I treated all the drains, but now I only do once a month for maintenance. Anyone suffering with those demonic flies, get this!! And also try the cup over the drain trick and grab some of those fly strip traps to hang in the areas where you're seeing the flies, worked like a charm.

Takes awhile to work, but works. Very expensive for the number of applications having to use

After battling fruit flies for over a year to no avail and seriously having them mess with my mental health - I used this on my bathroom sink drains, shower drains, and kitchen drain and I stop seeing fruit flies within a week. I’m still in disbelief because I have been dealing with them for over a year and nothing worked. The boiled water didn’t work the gobbler stuff didn’t work. Nothing worked except this. FYI, it’s been over a month now and still no fruit flies. It’s honestly a miracle.

This drain cleaner is Awesome! We had drain flies due to years of unknown buildup in our kitchen and bathrooms. I tried vinegar and baking soda with boiling water but gave up. Then I found out about InVade Bio Drain. So happy... After 1 overnight application of 8 ounces per location, through a squirt bottle we only had a few flies. Repeated 2 more times and they're gone! I'll use this cleaner 4 times per year as maintenance. My septic guy says this is the only cleaner that he recommends. For a man who has been in the business for over 50 years that is quite a compliment to this product.

I have used the whole bottle and it hasn't helped my problem at all! Used it within 7 days and nothing, waste of money!
