Invade Bio Drain Gel - Enzymatic Activity

The microbes used in InVade Bio products are a multiple-spore blend designed to provide exceptional performance over a wide range of organic waste-related applications, including drain line and grease trap treatment, hard surface cleaning and deodorizing, septic and waste treatment, and carpet and fabric care. The strains were selected for their superior enzymatic activity against specific substrates including proteins, carbohydrates, and fats. Their combined synergistic value is demonstrated in enhanced cell growth, germination rate, and effectiveness over a wide range of organic substrates. They will perform in both aerobic and anaerobic environments. Spore-formed microbes are superior in that they are more resistant to chemical cleaning agents. When the spores are in contact with their food source (the target organic matter), they generate bacterial colonies. These bacteria then digest organic matter. While the bacteria can be killed by chemicals, the spores survive and can again produce bacterial colonies when conditions become favorable (e.g. the chemical is rinsed away). The spores consist of Bacillus strains (multiple), with no detectable Salmonella or Shigella. Strains are included which produce Lipase, Protease, Amylase, Cellulase and Urease enzymes with aerobic and facultative anaerobic pathways. They are effective at a temperature range of 38-145 °F. In laboratory tests, the microbe counts double in 20 minutes when in contact with their food sources. They will perform in a pH range of 4.5 to 8.5. They are stable for two years if stored in the range 35-95 °F

Sugar Snakes in Drip Trays-Restaurants, Food Service, Convenience Stores

Invade Bio Drain Treatment may also be used in soda fountain drip trays to prevent or minimize something called "sugar snake". Sugar snake is a polymer that grows in drains where sugary drinks constantly drain. In the second stage, the polymer elongates  and crystallizes to a rigid, hard, cellulose microfibril. When left untreated, these polymers "grow" and choke drain lines in Ice & Beverage Dispenser (IBD) machines.

The consequence of sugar snakes not treated are costly drain line backups and foul, vinegar-like odors. Also, sugar snakes contribute to poor sanitation. Sanitation is critical for any pest control measure. Each year, fast food restaurants, convenience stores, and other foodservice facilities incur expensive emergency plumbing bills to clear clogged IBD drain lines.

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.
Review by Doug / (Posted on 7/28/2020)
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.
Review by SB / (Posted on 1/27/2020)
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!

I am well pleased with the products I ordered..
We had started having trouble with drain flies..there wasn't a large amount of them but there was enough in different places in our home to be a neausance and I would see them in my coffee I was drinking! Uugg!! So I looked on line and found this product..used it real good one time and it got rid of the drain flies..it was amazing to me how well it worked..Thank you very much@

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.

Great stuff
I bought the drain fly kit. Within 5 days, bugs were dead
Review by Mauidave / (Posted on 9/3/2019)
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!!!
Review by LeeinNC / (Posted on 7/23/2019)
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.

It works!
It worked, and quickly. About two days after application the flies had disappeared and haven't come back. Very satisfied.
Review by Scott / (Posted on 8/8/2018)
Worked like a charm!!’n
I don’t generally write reviews but i was so happy to be rid of those pesky drain flies that i had to. I started using the products two days after i received them and after two days i was not seeing anymore flies. I continued to use it a few more days just to be sure and i haven’t had a problem since. I had been dealing with those flies for weeks and used every recommended “cure” icoukd find. This product is the only one that did what it said it would!!

Outbreak Defender is GOLD..Biodrain not so much use dilute ammonia instead
Took a while to find out what and where these drain flies were coming from. It is old apartment building and i like yogurt for breakfast.I would drain the liquid on the top of my yogurt container into the sink. After about a year of doing that i had drain flies-all of the sudden one morning it was a blizzard of these flies I wasn't sure what they were?.Or wher from?
I was so happy when I found dyi...Outbreak Defender is GOLD..but Biodrain not so much. I read that cleaning drains with 1/4 cup ammonia to a quart of hot water is best for drain flies. I tried that, much less expensive and very effective. the 2 bottles of Biodrain worked for a while then would need expensive replacement..Ammonia much more affordable. I keep the sink plug in when i am not actively using the sink now.I have a spray bottle Outbreak Defender handy where ever i sit..I doubt i will need to replace the bottles when and if i use it all but it is expensive insecticide for every insect i have encountered since i got it..spider, ect. i have 4 bottles of Outbreak Defender to use up....gotta to love plain old Ammonia for drain flies! wish i had known but Outbreak Defender when drain flies were driving me crazy and they were every where is GOLD! Biodrain not so much

Seems to be the easy fix!
We've had recurring invasions of phorid flies since last summer, originating from a neighboring dumpster abutting our back fence and back doors. So we quit using those doors, but the problem - and the flies! - kept coming back, as they were by then breeding inside and not just flying in. It's now been about a month and this stuff seems to have done the job. After repeat visits from a pest control company with no permanent fix (altho they SAID they had one - WRONG!), the Invade Bio Drain gel seems be the easy fix to that now-no-longer-occurring problem!
Review by JMD / (Posted on 4/23/2018)
Impressive outcome!
I had a gnat/flie problem, along with some bad odors that came from my bathroom drains. I found Bio Drain and ordered it. I had a delivery issue, someone took my stuff. This company promptly re-sent it, at no cost, thank you so much. The results of using this product has eliminated the odor problem and I dont have anymore gnats/flies either. Impressive. I highly reccommend Bio Drain and I rarely have a recommendation like that. Worth every penny.
Review by Biodrain to the rescue / (Posted on 4/20/2018)
Got the job done, PERIOD!
I moved into a new home, immediately started to notice drain flies, I thought it was my homes septic tank so I had it emptied. That didn't solve the issue, so I went online to learn about these "harmless" flies (only harmless if they are not invading your home) which I felt was happening. I wound up on this website and watched the tutorial by these 2 guys, the tutorial video made me feel like these guys new what they were talking about. So I made a purchase of 5 gallons of this product. I wasn't 100% sure where the flies were coming from so I wasn't going to risk it. I followed the instructions and then some in every point of entry........2 weeks later, I feel like I live in a completely different home, as if these flies never existed. It works! don't second guess it, the two guys new what they were talking about recommending this product.

Fantastic product
Great product, this stuff really works. Had a drain fly problem on a 15 yr old boat, some of the drain pipes even used to clog up. It did take a couple of days with daily treatment of all 20 sinks and showers to kill the drain flies, but they are completely gone now. I use it once a week to maintain clean drains, and surprisingly one drain pipe that we had to take apart and clean every 6 months is completely clean!!! Seriously this stuff really works, and it smells great too! Just be sure to wipe up any spills immediately as it will stain.

Bummer I think its a winter must
old apartment....VERY,Very cold.

Do I want to rinse to the garbage disposal or throw out in garbage and carry outside more often to dumpster . Until it gets warmer I will use this to maintain the garbage disposal and go outside less often
Review by Lynn / (Posted on 1/8/2018)
I ordered Invade Biodrain with Outbreak Defender for fruit fly like flying insects that appeared heavy out some where?. Outbreak defender helped me get rid of all the flying insects that where alive when i got it (within 3 days)then BioDrain prevented new ones..So after 10 days I have no more of those flies. I think they were coming from my drains. I think it was because I like yogart every morning for breakfast. After i scoop out a serving I just rinse the bowl for breakfast again the next day.After a few years that pattern must have provided a place for the flies to lay their eggs.. I posted an even more enthusiastic review under Outbreak Defender. It was both product that fixed the problem for me and I thank DIY for their response to my emailed question when i was so afraid i would never get rid of them. Thanks, Lynn

Trial and error
This worked well to clean the drains. It turned out I did not have drain flies though. After attacking and trapping the flies, I figured out they were gnats. I had transplanted a potted plant and soil I purchased apparently had some type of gnat eggs in it. Ended up treating soil with insecticide and putting a top layer of small rocks/gravel. Gnats immediately gone next day. My drains are super clean now though!

It Works
This product works as it says it will. It smells great, is easy to use and lasts a long time. The cost is reasonable for the amount you get, too. I will continue to purchase this product when needed.
Review by Daisy / (Posted on 10/20/2017)
Great product
I am so pleased with this product! We have an old house with old pipes and the place was infested with drain flies. I used it twice in the basement floor drain and once or twice in the rest of the drains in the house and the results were almost instant. After a few days, we haven't seen any flies in the house! Definitely get this if you are bothered by drain flies. I couldn't stand them and now I don't have to worry about them.

Great Product, Easy to use.
I had drain flies in every drain in my house. Nasty. I used this stuff twice and haven't seen a single fly since. This stuff rocks!
Review by MICKEY / (Posted on 9/1/2017)
It actually worked!!!
I was totally skeptical!!! Seriously - I've been using every method I could find online to kill those little buggers!!! ONE application of this stuff in the drains, and within a few days they were all gone!!! I was SHOCKED!!!!!!! They don't die instantly - it takes a few days. But once they left, they were gone for good! I'll continue to treat to prevent anymore from showing up. I know how quickly a few turn into a ton!!

This stuff smells really good too!!! I wanted to eat it - I'm not surprised the flies LOVED it!!! Very fruity and sweet!
Review by Angi / (Posted on 9/1/2017)

This stuff is great. Gets rid of drain flies very quickly. Love the orange scent, too. It is the only thing that works.

Excellent product, works really fast.
I was having a problem with drain flies in one of my bathrooms. I ordered a gallon. It did not take a lot and worked incredibly well. I would recommend this to anyone.
Review by Janie / (Posted on 8/12/2017)
I bought the small bottle to see if it really works and it did. I have just purchased a 1 gallon container and plan on using this on a regular basis. The product has a thicker consistence like syrup and sticks well to the drain walls. It also has a nice citrus smell, which is very nice. Great product that I would recommend to everyone.
Review by James / (Posted on 8/10/2017)
Worked great. Takes a few days to work.
Had a horrible problem with annoying, tiny black flies (fruit fly sized, but not attracted to fruit) that were hanging around drains. They were also attracted to lamps at night. I tried many different things in the drains, but nothing helped. I was killing them with a bug zapper (tennis racket type) and sweeping up piles of dead flies. I used this product according to instructions and it took a few days to notice a difference, but now there are days I don't see any flies at all. I still see one occasionally, but at least it's under control now. Will continue to use this for maintenance. It smells great and works!

What Drain Flies?
I finally researched the little black flies that fly slow & crooked in the bathroom and basement and was led to this site. This orange stuff is awesome! Treated all the drains 3x so far over 2 weeks but used way more than 4 ounces per treatment. Went from seeing a dozen a day to just 1 or 2. Finding dead ones on the windowsills in the basement too. I love that it's natural since I get migraines and avoid strong cleaning agents and bleach whenever possible.

Product is working - smells great
it is a bio product which takes some time to work. Still using every other day to clean out a kitchen sink drain for about a week now. it flows but can still tell it has more grease to cut through. try it...
Review by RonMon / (Posted on 3/1/2017)
THANK YOU- works like magic without a terrible smell
I don't know how this could get anything less than 5 stars. I bought this one night in pure frustration and almost cancelled because I thought "no way could this work" ... boy am I glad I didn't cancel. This stuff exceeded my expectations. I had tried EVERYTHING before getting this. I had never had an infestation like this before and I had never even heard of the buggers being in the drain..but desperate times and all. Within 3 days totally cleared. We did every day for a week to be sure. Then went to every other for a week. Now I do once a week so they will never come back and I will always keep some on hand. I have an autoimmune disorder and just can't have chemical smells around at all, I'm SUPER sensitive to bad smells and this not only worked, but didn't smell terrible and didn't leave any stains or marks etc.

Works great!! Drain flies were gone in 2 days!
Review by TJ / (Posted on 7/12/2016)
I had drain flies in my kitchen and bathroom for about a month before taking action. I ordered 2 of the 1-Qt bottles of Invade Bio Drain gel, and the CB-80 insecticide spray. I only had to use the Bio Drain gel, and the flies disappeared within a few days. Just poured into my drains before work in the morning every other day for about a week. I decided not to use the spray because I am pregnant, and thought it's not worth the risk. The Bio Drain drain worked perfectly, and I love that it is safe. Flies have been gone for about 3 weeks now. I would get the product again if this problem comes up again, and definitely recommend it!
Review by Happy Mom / (Posted on 7/4/2016)
Bathroom sinks: Not sure if Invade works, but
You must remove the sludge they are breeding in first, or they will come back. We found that Invade got rid of them temporarily, used two liquid 2 bottles of it on the first go, but they came back in a couple of weeks. After some research, we used a Gel type drain cleaner to clean out the sludge. I believe it was in the sink overflow drain as well so I plugged it from the bottom, then filled the overflow and let soak. I could actually see some pretty nasty stuff come loose. We then used 2 more bottles of invade & the Hot Spot Foam. So far it seems to have worked.

Great at Prevention!
I had noticed drain fly larva in my tub, and emailed the team at DIY for help. I ordered this product too late to help with that issue, but am confident that it's now working as a preventative to help in the future. Smells great and haven't had an issue since! It did stain the tub a bit, but eventually wore off after being scrubbed.

Seems to work
Good idea for a product. Seems to get rid of fruit flies for at least a week or so. Reasonably easy to apply, thick, and smells okay. The only problem is in closing the lid, if you get any product on you, you have to undo your hard work on the drains by washing your hands. Wish we could find a more permanent fly solution, too...

I was a bit skeptical at first and after the first 3 treatments but after just over a week I was very pleased with the results the flies are gone.
Review by Dug / (Posted on 1/19/2016)
Didn't get the job done
I did some research on the internet concerning our drain flies. I bought this product in ample supply and used it according to directions, but it didn't meet expectations. If it made any difference, it wasn't noticeable. After calling a local exterminator, we were advised to pour a small amount of bleach in every drain right before going to bed each night for at least a week. This definitely was the solution we were looking for. Drain flies are gone, and drains are sparkling clean with no organic residue for flies to reside or reproduce. I wish I hadn't wasted money on Bio Drain. Just make sure you wipe the chrome plunger top and drain top (circle) after applying bleach, as some corrosion may occur with repeated bleach application.

************ DIY Response **************

Bio drain is a slow acting formula and through many years of both using and selling it I have never seen it fail. I think it is likely that the Bio Drain removed the film of organic debris in the drain so the flies no longer had a breeding site. The bleach was applied as the existing adult flies died off and it appeared as though the bleach was responsible.
Review by Rusty / (Posted on 1/19/2016)
Doesn't work
I have been using this product for about a month now, following the instructions exactly as written, and I still have flies coming out of my drain. I don't think this stuff works and I just ended up pouring my money down the drain

I'm sorry you are still having flies. Drains are only one of many potential breeding sites for drain flies. If you haven't yet please give us a call at 800-476-3368 and one of our techs can help you eliminate the problem.

great results
We have had a recurring problem with the sewer flies the past two years-each time a little worse. We used the gel seven months ago and saw a dramatic decrease in the flies. We left the house for 5 months and when we returned it will filled with dead flies! We treated again 3 months ago and have not had any flies since that time.

I bought two bottles thinking for sure this was not going to be as effective as it sounded. But in truth the problem was quickly solved without going through both bottles. I will continue to use the bottles on an ongoing basis and would tell anyone wanting to get rid of those pesky sewer type flies, this worked as advertised and super quick!

We had persistent fruit flies in the kitchen, even with no fruit left out on the counters. I finally diagnosed the problem as an infestation of drain flies in the kitchen sink.

I tried several other products and methods, including taking apart and thoroughly cleaning out the garbage disposal. I didn't want to order something off the internet, but nothing from Home Depot or the local Hardware store would do the trick.

I treated my drains with this (follow the instructions!) and the flies are gone. It took about 3 treatments, but at only 4 oz. for each time, I still have most of a bottle left. The best part is NO MORE FLIES! :-) I'm very satisfied.

i noticed more and more dead drain flies in the sink.Live ones were actually still flying around.I have been using Bayer Advance Pest control and had immediate results.It has cut it down about ninety nine percent.It is also a lot cheaper and effective.

I can't believe how this product worked so well to solve a problem I've been fighting for 3 years. After about 4 treatments there are no drain flies in my bathroom. And I have 3/4 of the gel left!

Great product!
We moved out of our home (with a septic system) into a new place. Then we put our old house up for sale. I went to the old place daily to keep it clean etc. After a week of vacating, we had dozens and dozens of black "trap" flies everywhere! It was horrifying while trying to sell our home!!! I learned that these flies appear when water ceases being run through the various sinks in the house and the flies come up from the septic...gross!! So I went on the Internet to research getting rid of these flies and discovered DIY Pest Control and this amazing product. The over-the-phone help from the company was great. He walked me through exactly what was causing the problem and how to use the product. We saw immediate results. That it isn't a chemical & smells so good were pluses!

Excellent Product
Had lots of drain flies. Used this every other day for one week. No more drain flies. Great product. If you have drain flies this will fix the problem.

Great Product! Got rid of the drain flies
We have been having issues with drain flies from one bathroom for over a year now. Nothing out of hand, just a few hear and there. We kill them, then a day later, another shows up. We are on septic. Have tried a couple other things, nothing has worked. I used this product over a month ago, while they were active. I did both sinks and the bath in this bathroom. I put more than recommended because I bought the gallon. I used it only once, and I have not seen one since! This product is great. I highly recommend it.

I would definitely recommend it.
I wasn't sure how this would work, but we have noticed that the amount of drain flies has reduced even are beginning to disappear. My husband even asked if we had more because we hadn't put any in the drain and they were starting to come back so that in itself is recommendation. It really does work. Before we run out I will get more so it is always on hand. I like the fact that it's not toxic and if it gets on you I'm not worried it's going to start burning my skin. Although I do wash my hands as soon as I'm done.

I used this product to treat sewer flies in my kitchen. It worked quickly and the problem didn't come back. I really like this product because it's not a chemical. It smell good and it goes a long way.

Used Bio Drain for drain flies.
I purchased two one quart containers of Invade Bio Drain to treat six household drains. All 2" or smaller. I was attempting to eliminate some pesky drain flies. I initially thought that there were fruit flies in the house so I purchased some traps for them but the rascals ignored them. When I complained DIY Pest Control suggested that perhaps I had Drain Flies and that if I used Invade Bio Drain I would be able to control the infestation. I used the product as instructe and noticed a significant reduction in the fly population so I must have gotten the right product for the right pest. I've used 1 + 1/4 qt of the product for four applicatons every other night. It's now two weeks later and I've re-applied the product twice (once a week). I still have a couple of the critters flying around so I know it will be a long haul to conquer the little beasts but I will continue to use this product until the foe is vanquished.

Great product!
I highly recommend the Bio Drain. It immediately took care of an odor coming from an otherwise clean drain. I saw no evidence of drain flies, but the product has a pleasant odor and is extremely effective! It is a necessary product in keeping the drains clean and smelling clean too!

We tried many things, including the advice by a professional pest removal company, and nothing worked. The Bio Drain worked beyond our expectations, eliminating the infestation of fruit flies in our kitchen sink drain. Totally eliminated them in one week! So far, one month later, no fruit flies. Great product, and safe, too

Works as advertised-same stuff the pro's use
If you have drain flies, get Invade gel. Boiling water, bleach, dangerous chemicals & insecticides can be harmful and they just don't work. It took a while, it's gonna' happen overnight, but the beneficial bacteria in the Invade gel did the trick by devouring the soap scum and detritus in the drain traps where the larvae live and eat. Once the larvae have no soap scum, grease , etc. to hide in and eat you will soon have no more drain flies hatching. You don't need to have a professional exterminator do the work, You just pour some gel into the sink drains to coat all around the the pipes with the gel bacteria yourself. The pest control technician that treats my yard saved me a service call by tipping me off about buying Invade online They don't sell it direct and charge a service call to do what I could do myslef. Also, If you have a septic tank do not fail to put beneficial bacteria down the drains periodically, too, to keep the beneficial bacteria percolating.

It works!
After trying several other methods, I purchased a bottle of Bio Drain for my Son & Daughter-In-Law to use in their home to stop the madness of a fruit fly epidemic! Bio Drain saved the day! I would recommend this product to others who are fruit fly haters too! It works!

drain flies
This has not worked for me. It's been two weeks and I've seen no improvement. I've followed the directions exactly. Will give it a few more days.

DIY Response: You might want to try placing a clear piece of tape with small holes punched in it over the drain. This will help you identify if the flies are actually coming from the drain. It's possible that there is a different breeding source for the flies in the area. Give us a call at: 1-800-476-3368 and we can walk you through troubleshooting the problem.

Fruit Flys Dead
I wasn't sure if it was going to work. 2 days most of them were still around, but after 5 or 6 days they are all gone.

Cut the pest numbers in half
Invade Bio Treatment cut the pest numbers in half after a couple of applications. I will continue the clean out , then maintenance.
Worked well!
