32 oz InVade Bio Drain Quart Restaurant Drain Gel Organic Treatment ~~ Eliminates Odors, Drain Flies, Phorid Flies, Fruit Flies, and prevention of 'Sugar Snake' in soda machine drip trays

Easy to use and very effective. Lack of strong scent was a plus due to asthma in the family.

Twice a year living in the RV park we get a sewer/drain fly bloom. The have been using this now for quite some time and we personally no longer have the bloom in our RV😊

This product got rid of a funky smell in my kitchen drain that bleach wouldn't kill. It's also great for eliminating sewer gnats that come out of the bathroom drain. Easy to use by reading the directions.

This was very deceiving. The picture shows a gallon of the Bio Drain and I thought that was what I was ordering. My own fault but you need to change the picture to match the product. I could have ordered the very same quart size much cheaper and on Prime too. I'm sure the product will work just fine but the picture ad is just wrong!

I will need to order more product since we have a lot of drains to treat for several weeks for the full effect. Also they have a product for garbage disposals, I will order that from Amaxzon next. I called the Company direct and they were very friendly and helpful.

Used according to the instructions, but to no use, it did not work at all! Not worth all the money charged!

it works! but you have to follow the directions. our second bottle is used as preventative maintenance, which is recommended. we started using this less than 6 months and have not seen the flies in a while.

It's a good product, just have to use often. Drain flies no longer in face bowl, but still in tub.
