Product Overview

InVade Bio Drain Gel combines citrus oil and premium microbes in formulation thick enough to coat the insides of drains allowing it to eliminate odors and eat through scum. When first using InVade Bio Drain apply every other day for the first week and then continue to use once a week afterwards. Use InVade Bio Drain in the drain lines of the soda machine drip tray to clear out sugar snakes that eventually clog the drain lines.

InVade Bio Drain can be also be used with a hose end sprayer or in a mopping solution. The citrus oil has a great scent and provides extra cleaning power.

A Pump For 5 Gallon Pail can be purchased separately if needed.

InVade Bio Drain has recently transitioned to dye-free formulation and will no longer be an orange-colored liquid.

How InVade Bio Drain Gel Works

InVade Bio Drain Gel contains natural microbes, citrus oil, a gelling agent, and an emulsifier. The microbes consist of bacillus bacteria that eat away naturally at the organic scum buildup in drains and on floors and other areas with frequent food and water contact. Citrus oil aids in cleaning and also leaves a fresh scent after InVade Bio Drain is used. The remaining ingredients thicken and stabilize the liquid, helping it to coat drains and other treatment surfaces.

InVade Bio Drain Target Pests

Organic buildup in drains that is the breeding site for odors, drain flies and fruit flies

PESTS CONTROLLED WITH INVADE BIO DRAIN: Odors, sugar snakes (in soda lines), surface and drain scum, organic buildup.

Target Uses of InVade Bio Drain Gel

Use InVade Bio Drain Gel to eliminate odors and organic buildup in drains and soda lines, and on surfaces such as restaurant floors and dumpsters. InVade Bio Drain is a perfect part of treatment for pests such as drain flies and fruit flies that breed in these areas. InVade Bio Drain can be used in bathrooms, kitchens, or other areas in homes, businesses, and institutions.

Treating clogged drains with hot water, bleach, ammonia, or other ordinary drain cleaners is inefficient. Only the regular use of a highly concentrated, professional strength bio-sanitation product like InVade Bio Drain will adequately cut through drain scum to prevent odors.

Use InVade Bio Drain in soda fountains to eliminate "Sugar Snake": Sugar snakes are the long, crystallized, rigid polymers that grow and clog drain lines in soda fountain machines. These polymers are caused by certain bacteria left behind by sugars when these machines are not adequately maintained. Sugar Snakes that are not treated may lead to costly drain line backups and foul smelling odors. Treat soda fountain drain lines with InVade Bio Drain to prevent or minimize sugar snake problems.

InVade Bio Drain can also be purchased in our Drain Fly Kit.

ACTIVE INGREDIENTS: Natural Microbes, Citrus Oil

InVade Bio Drain (Gel) Application Instructions

To use Invade Bio Drain:

  1. If drain to be treated is not used regularly, first moisten the drain with 1 to 2 gallon of warm water before treatment.
  2. Apply product at periods of time during the day when drains are in lowest usage.
  3. Apply 4 oz to each drain around the edges, making sure to coat the sides.
  4. Repeat daily for 5-7 days and then every 1-2 weeks for ongoing maintenance.
  5. For drains that have a very heavy layer of scum, clean the drain with a brush before beginning treatment for immediate results and then maintain with InVade Bio Drain to prevent further build-up.

NOTE: InVade Bio Drain is not a substitute for general sanitation. Sanitation is key to eliminate drain flies! To eliminate drain flies, fruit flies, and other fly pests, a total sanitation program is key. The problem area must be cleaned completely, including eliminating standing water as much as possible and properly disposing of food waste into a plastic bag in a trash receptacle with a tight fitting lid. When the area has been sufficiently cleaned, the drains may be attacked with InVade Bio Drain. For treatment of floor or trough drains, first remove the screens and scrape off any organic matter.

* Always read the product label completely before use.

A quart (32 oz.) container yields 8 drain treatments, 32 soda drain treatments, or 4-8 gallons of diluted solution. A gallon (128 oz.) container yields 32 drain treatments, 128 soda drain treatments, or 16-32 gallons of diluted solution.

Standard Application Dilution rates / Mixing Ratios for InVade Bio Drain Gel:

  • 4 oz. per drain per treatment – Daily or every other day for active infestations, bi-weekly for maintenance - Drain buildup, breeding site for drain flies

    Bye bye annoying drain flies!

    By Liz on 11/27/2012

    Verified Purchase

    I had tiny drain flies coming up from my basement floor drain. I threw a gallon of bleach down the drain and that didn't faze them one bit. They were back the next day. After turning to the Internet for advice I found favorable reviews on Bio Drain. I bought two bottles. I followed the directions on the bottle and noticed within a couple applications the flies were gone. I kept using it for a week and they are completely gone. It's been 2 weeks now and I haven't seen any. I'm not sure if it will continue to work long term but I have another bottle should those pesty flies return.

    Nice smell, seems to be working well

    By Jojo on 06/21/2011

    Verified Purchase

    This product has substantially helped reduce the population of our drain flies. There are still a couple around here and there, but we haven't finished the treatment yet. There was a very quick and noticeable reduction right away.  Also, it smells really nice for a pest control product (like oranges).

    Invade Bio Drain is a Great Product

    By Lynne on 04/16/2010

    Verified Purchase

    My bathroom drains had a very mildewing smell. This product took care of the odor by the second application. The gel itself has a pleasant odor and is easy to use. I will definitely purchase the product again. Also, I will be quick to look for other products from this company!

How do I get rid of drain flies in the kitchen?

I am having a big problem with drain flies in my home kitchen. My problem is that I cannot remove the cross bars in sink drain, so I will not be able to apply the gel to the sides of drain. Before I purchase, I thought I would ask your help. These things are really annoying, and I would like to rid them, prior to the holidays. Thanks!

Most people cannot remove the cross bars on the drain and that is ok.  The Invade Bio Drain and our other gels have a spout on the top and you can squeeze the bottle and "shoot" the product out the spout onto the sides of the drain.  Also, if you treat along the outside perimeter of the drain it should run down the sides where it needs to go.  You may want to consider our Drain Fly Kit which has a very high success rate.
