InVade Bio Drain

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.

Active Ingredient: Microbes and Citrus Oil
Target pests: Eliminates Odors and prevents Sugar Snakes
For use in: Direct application to drains, soda drain lines and drip trays
Pet safe: Yes, when used as directed on label
Yield: Apply 4 oz to each drain once daily for one week Yields 32 applications
Manufactured By: Rockwell Labs (UPC: 837654797242)

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 biosanitation 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
  • 1 oz. per soda fountain drip trays – Weekly - Sugar snakes and similar buildup
  • 4 oz. per mop bucket – Standard mop bucket
  • 4-8 oz./gal. of water – Surface cleaning with a sprayer, such as for dumpsters and trash chutes
  • 1/2 to 2 oz./gal. of water – Hose-end or power sprayers

InVade Bio Drain is for use in the following areas:

No restrictions on use sites. Intended for drains, floors, dumpsters, trash chutes, bathrooms, and similar surface cleaning.


See above for general directions. InVade Bio Drain Gel may be used full strength in drains or soda fountain drip trays, or diluted for mopping, surface applications, or foaming.

  • To foam, use 4-8 oz. in a gallon of water and add 2-4 oz. of foaming agent. Apply using a foamer.


InVade Bio Drain Gel is not intended for outdoor use unless treating surfaces on or in dumpsters or similar structures. In power sprayers or hose end sprayers apply at a rate of 0.5 to 2 oz. per gallon of water.

    5 of 5 stars  Invade Bio Drain is a Great Product
    By Lynne in Vancouver, WA 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!

    5 of 5 stars  Bye bye annoying drain flies!
    By Liz in Chicago, IL 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.

    By Jojo in Miami, FL 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).

    I recently bought Invade Bio Drain to get rid of a few drain flies. I wasn't sure which drain they were coming out of so I treated all my drains. Since using this product, I have not seen anymore drain flies. I plan to continue using this product - it really works! Thanks, Carol

    By Charles in ENOLA, PA on 08/25/2011
    Verified Purchase

    8/9/11-treated kitchen & bathroom drains. I thought the kitchen drains (sink/disposal) were the source of our drain fly problem, but did bathroom drains too. 8/11/11-treated kitchen drains every other day thru 8/17. No sign of drain flies since 8/15 treatment. 8/21/11-started once a week treatment of kitchen drains as recommended on bottle. 8/25/11-no sign of flies, so product is doing its job. Hooray!

    By Joseph in Washington, DC on 05/12/2016

    I don't know where they came from, but these flies can drive you nuts! Took a chance and bought Bio Drain and the spray insecticide (C80). Together these two items got my problem under control. I notice that when buying fruits and vegetables this problem can manifest itself. You have to stay on the problem, because these flies multiply very quickly and can get out of control fast.

    Expert Response   Expert response:
    It is very important that you inspect the entire infested rooms for drainflies. Invade Bio Drain will do a great job at helping to remove the debris that builds up in drains but by itself , does not kill drain flies. While they often do breed in drains, their name can be a misnomer. Please take a few moment to read our Drain Fly Guide. This guide includes step by step instructions, how to videos and pro tips:

    By Michelle in Burr Ridge, IL on 08/23/2015

    We had these tiny flies, mostly in our downstairs bathroom. Couldn't figure out how to get rid of them. Tried baking soda & vinegar, bleach, nothing worked. This stuff did the trick after one application! Now all it takes is 1/4 cup every third day - hopefully at some point they won't return. But this is at least an easy remedy - thank you!!

QHow 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!

AMost 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.

QDrain gel is very thick and doesn't really get into the drain. Should one pour a bit of lukewarm water into the sink to force it down into the drain?

AYou can, but Drain Gel  is supposed to be thick so it coats the drain as it goes down.  You should direct the gel just down the lip and sides going into the drain.  You should not coat on top of the drain on the sink so it won't go down the drain.

QDoes Draino kill the microbial action of Invade Bio Drain? I had to use it between orders.

ADraino contains some very harsh chemicals and most likely would kill the microbial action of the Invade Bio Drain. We recommend rinsing the drain very thoroughly before reapplying the drain treatment.

QDo you pour water down drain after putting drain gel down drain? Or do you let it sit 8 hours unused and the next morning run water down drain?


We recommend that you apply 4 oz of Invade Drain Gel in each drain opening when they are not in use. You should refrain from running water down the drain after application so the product has time to be effective in breaking up the organic matter in the drain. We also suggest appling 2-3 squirts of Gentrol IGR Aerosol after the drain gel to impede the insects reproductive cycle. Please let us know if you need anything else.

QWhat is the best combine use when using Bio Drain and Gentrol to control drain flies and phorid flies?
If you put the biodrain in, does it take away the effectivness of the gentrol?

AGentrol IGR should be mixed with water and can be used inside the downspout and catch basin area of the drain. This application will be completed before you use the Invade Bio Drain. You will repeat applications every 2-4 weeks.  The Invade Bio Drain should be used by itself. You will use this to coat the drain and kill the microbes inside the drain.
