DF 5000 Drain Gel

Clean and maintain your drain with DF 5000. DF 5000 Gel drain treatment utilizes an extra-thick advanced blend of special bacteria cultures and free enzymes to coat drains and cut through decomposing organic materials. DF 5000 gel also improves drain flow, leaving behind a fresh scent and preventing costly blockages.

DF 5000 Drain Gel is NOT labeled for control of drain flies or any insect pest. DF 5000 is a drain cleaner. For control of drain flies please see our Drain Fly Kit which comes with complete instructions and is advised for people with new infestations of Drain Flies.




How DF5000 Drain Gel Works

DF5000 Drain Gel is an innovative blend of bacteria cultures and free enzymes in an active stabilization medium designed to reduce or eliminate drain fly food sources that promote drain fly development. The heavy gel formulation coats drain lines to attack decomposing organic masses and quickly break down gelatinous organic material where drain flies develop. DF5000 is NOT an insecticide, rather it is a drain cleaner designed to keep drain lines free of the organic matter that acts as a food source and egg-laying area for drain flies.

DF5000 Drain Gel Target Pests

Drain fly food sources and breeding areas

PESTS CONTROLLED WITH DF5000 DRAIN GEL: Organic buildup in drains

Target Uses of DF5000 Drain Gel

Use DF5000 Drain Gel to eliminate odors and organic buildup in drains in bathrooms, kitchens, and floors. The decaying organic matter found in the “j” traps in floor drains and sink drains provide both a food source and breeding ground for drain flies, fruit flies, phorid flies, and other fly pests. These fly pests cannot be eliminated unless this breeding ground is directly attacked. 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 gel like DF 5000 will adequately cut through drain scum. DF 5000 Drain Gel is NOT labeled for control of drain flies or any insect pest. DF 5000 is a drain cleaner.

ACTIVE INGREDIENTS: Bacteria cultures and free enzymes

DF 5000 Drain Gel Application Instructions

To use DF 5000 Drain Gel Treatment:

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. DF 5000 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 DF 5000 to prevent further build-up.

NOTE: DF 5000 is not a substitute for general sanitation. 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 treated with DF 5000 Drain Gel. For treatment of floor or through drains, first remove the screens and scrape off any organic matter. Keep out of reach of children.

Always read the product label completely before use.

Each quart (32 oz.) bottle yields 8 drain treatments.

    1 of 5 stars  Surprise, surprise: eco-friendly stuff won't rid you of drai
    By Steven on 01/03/2012
    Verified Purchase

    We returned from a week's trip to find a shower drain infested w/drain flies for the 1st time. Common-sense remedies (boric acid powder, "Liquid Pipe Snake") didn't work (after several weeks), so I found myself here. Reading the majority of good reviews, I thought I couldn't go wrong. I followed the treatments exactly - but after 5 treatments, the shame of drain flies was back. I had enough left for a couple more days, so I figured that would do it. Nope, they were back in full force - "eco-friendly" cleaning means NOTHING to gnasty gnats! At my final straw, I decided to try an insect spray; trouble was that spraying DOWN into a drain doesn't work, when the can needs to be upright to spray! So, I made a cup out of foil, went outside (to avoid the aerosol smell) & sprayed some "OFF! with DEET" in the cup (2 tbsp or so) & poured it around the perimeter of the drain. Next day - NO FLIES!! I did one more treatment as insurance, but an oz. of DEET was worth 2 lbs. of the DF5000 "cure". The moral? If you want a VERY expensive eco-friendly-drain-fly-house-cleaner, buy DF5000. If you want RID of the DFs, get some cheap "Liquid Plumber Gel" & a can of "OFF!". Clean the drain well, rinse w/hot water, & pour in the "OFF!" to sit overnight. I'm all for eco-friendly, but I'm not coddling drain flies. DR5000 is a TOTAL waste of money, if you REALLY want rid of these horrid pests.

    5 of 5 stars  DF 5000 Really Works!!!!
    By Bunny in Michigan on 07/09/2010

    After cooking for 56 years for my family I suddenly was invaded by many hundreds of Drain Flies for 3 years; coming out of the drain, hitting me in the face, landing in food I was preparing. They don't look or act like fruit flies. They hardly fly, they appear & disappear right in front of your eyes. So you can't see them to kill them?? They set up camp in every drain, on all 3 floors of my home.  A couple of them even flew into my refrigerator.  As a test, I kept the door shut for two hours, figuring I could get a whole DEAD sample to have identified; Guess what..after 2 hours they flew out alive!!  I always used bleach, boiling water, vinegar, baking soda...That didn't prevent them, or get rid of them.  After researching on the WWW, I discovered the info about DF 5000. I followed directions, IT REALLY works. You must treat every drain that 1st week!! Or they WILL move to an untreated drain. It took one season to get rid of them. I'm now reordering & so grateful there is a solution, and especially that it's a Natural One. Greatgrandmabunny

    5 of 5 stars  This works.
    By Db in Chicago on 06/29/2010

    We've had a residential drain fly problem off and on for a year. We tried numerous things only to have the drain flies return days later. So we were skeptical about DF 5000. But we bought DF 5000 and started to use exactly as directed. (The 4oz dose seems like a lot when you're pouring... but we made sure to use the full amount.) Within a day, there were no flies. It's been three weeks...no flies. We plan to keep up with the recommended maintenance. Order showed up quickly and in good shape. All in all, a better-than-expected experience.

    It almost seemed like we had a small baby boom of flys after we used the product in our one sink kitchen. I threw twenty bucks down the drain at a time when I couldn't afford it :( sad panda

    Expert Response   Expert response:
    This customer probably did not have drain flies.  This product rarely does not work, if they are coming from the drain.  Other flies can be in a house that are the same size as drain flies.  They could be fruit flies or they could be fungus gnats, which breed from potted plants.  We always recommend performing a test using glue boards over all of the drains in the room before treating.  If you get flies caught on the glue board you leave over the drain at night, then you KNOW it is drain flies and you know what drain to treat.  If you still have flies in the house but you are not catching any on the glue boards, then it is fruit flies or fungus gnats.

    By Rwagner66 in Palm Coast, FL on 02/12/2012

    In two days, 90% of flies were gone. Thereafter, I treated drains every other day, because it takes the little buggers at least two days to produce new adults. They were gone after two weeks. Hint: don't pour down the drain, dribble it around the periphery so it oozes down the inside of the drain pipe.

    I was very unsure of what the outcome of using this product would be but I was sick and tired of drain flies surrounding us during dinner time and all over the place.  I used the gel according to the directions and some tips from other consumers and turns out it worked great!!!  I don't have any more drain flies in the house at all.   I thought I would never see the light at the end of the tunnel but finally it is all taken care of and I'm so happy :-)

    5 of 5 stars  Drain Fly Gell
    By Lee in Burke, VA on 06/07/2011
    Verified Purchase

    I had a drain fly infestation that I was unable to control until I used the Internet to find out what was the best product for this problem. A number of sites, two from universities, suggested that DF 5000 was the only product that really worked. And it did, but I suggest that the problem first be addressed by having your drain professionally cleaned out, then use the DF 5000 in all drains that connect to the infected site. For example, my problem was in the bathroom sink, but this drain connected somewhere with the bathroom shower drain. Once the line was cleaned, I used DF 5000 in both drains for 5 nights and so far the fly problem is over. I will use the product weekly for a while, then monthly to ensure the fly issue is over.

    We have been fighting drain flies for over a year and even had the pest control company tell us things to do. A friend told us about Demon and their products so I tried the drain fly kit and it worked. I have ordered two more bottles of the gel and use it every 4 or 5 days and so far the pests are under control. I would highly recommend this product.

    Well first when I received this stuff it had leaked in the box so I lost like the first 4 oz...I called the company who only refunded me for about that value...the box was a mess. I have used this according to directions and there are still flies in one of my sinks!! Using this in 4 sinks (4 oz) each it goes very quickly...for the money that's a lot. I still have those irritating little flies in my kitchen!!

    These bugs are relentless. After the initial five days, we thought they were gone, but days later they came back with a vengeance. We're going to try to detach the pipes and scrub before starting the 5 day treatment again. The shipment came super fast and we were happy to get started with the product right away.

    Follow the directions, and it works. My drain fly/moth problem was horrific, though - literally thousands of them in my bathroom at a time. I opted to use the whole bottle night after night instead of leaving some for the once a month thing. I have *very few* bugs left, so I may buy some more, but overall this takes care of the problem.

QHow long do phorid flies live?
I purchased the DF 5000 to clear my drains and get rid of phorid flies. After using for a 5-7 days as directed, when can I expect to see the flies completely gone? In other words, how long do these annoying pests live?

AThe Phorid is a reproduction champion with females capable of laying forty eggs in twelve hours. Their entire live cycle is only about 25 days, so you can see how a population goes from zero to zillions in a very short time. How long it takes for the DF 5000 to get rid of the drain flies depends on how much organic matter has built up in the drain and if the DF 5000 is even getting in the right spot.  Sometimes flies can be breeding much farther down the drain than just in the trap under the sink.  Most of the time though the trap under the sink or tub is the issue and you just need to continue applying the gel.  It can take a few days or up to two weeks sometimes depending on how much matter has built up.  When this process is over you should treat the drains once every 30 days and you will prevent this from happening in the future.

QDF 5000 vs. Invade Biodrain?
I have drain flies and want to get rid of them. Both products seem to do the same thing. Is one stronger than the other? Is the Biodrain more environmentally friendly?

ADF 5000 Drain Fly Gel and Invade Bio Drain are pretty much the same and will do the same job for you. The main difference is that they are made by different manufacturers. Both products are very environmentally friendly.

QWhat is the best combination of products to use for Phorid Flies?
I was thinking DF 5000 Drain Fly Gel and/or InVade Bio Drain Gel as well as Gentrol Aerosol. What is the difference between the DF & InVade?

AIf the Phorid flies are breeding in drains that have a buildup of organic matter and DF5000 is used it can help get rid of those pests. Adding Gentrol to the treatment program can definitely help break the cycle of infestation. DF5000 and Invade are very similar and will do the same thing for you, they are just made by different manufacturers. You can also use insect glue traps to capture the breeding adults which will help you monitor the infestation and help eliminate them from the breeding pool.

QHow do drain flies get past the P trap? How much DF5000 does it take to get past the P trap and into the line?

AThe drain flies are not coming up from the P-trap. They are traveling inside from outdoors and reproducing in the organic matter that builds up on the walls inside the drain. You should use 4oz of DF5000 drain fly gel in each drain in the infested room every night for a week. We also have a drain fly kit that comes with DF5000, glue boards to monitor the infestation and an aerosol to knock down the flying adult drain flies.

QWill DF 5000 control sewer flies in the septic system?

QCan I use DF 5000 drain gel in toilet? Or can you recommend something?

AYou will usually see drain flies developing in a toilet only if the toilet is not used very often. DF 5000 probably won't be the best product to use in your situation if drain flies are coming from the toilet. You can turn the water off to the toilet and flush it so that the bowl and the tank are empty. Thoroughly scrub both, paying special attention to the area under the lip of the bowl and the tank. Scrubbing and cleaning these areas will help eliminate the decaying organic matter that these flies need to breed and develop in. While the toilet is drained you can apply Invade Hot Shot Foam to the tank and the bowl and let it sit overnight to clean all of the cracks and crevices that you may not be able to clean properly. Invade Hot Shot would be a good choice because it will expand to cover all of the surfaces you need to treat. This may need to be repeated a few times before you get rid of all of the gunk that can build up over time. All drains in the infested room should be treated with either Invade Hot Shot or with DF 5000.

QMust drain flies be treated at night ?
I retire to bed much earlier than the night owls I live with, so it's difficult to treat at night and expect no one to run water. Would treating in the morning after all night owls have left for school or work be as effective?

AWe really like to Drain gel to be able to do its magic for at least 7-8 hours. if you could manage a time like that, that the drains will not be used that will work too. Be sure to flush the drains with hot water after the product has sat in the drains.

QWill DF 5000 kill larvae in a shower pan by putting around the floor of the shower seams?
After a shower, larvae comes up through cracks in my tile around the wall of my shower. I have had it regrouted, but these still come up. Can I pour it around these cracks and will it kill the larvae in the drain pan. I have had this problem for about 4 months. No flies, just the larvae. Had exterminator check to see what this larva is.

ADF5000 will not kill any insects or larvae. DF5000 just helps to get rid of the organic matter that the larvae eat and that flies breed in. Until you get a positive ID on the larvae we are not sure what to recommend for you to use.

QDrain Flies: 40 ft long lanai drain
Any suggestions on how to use DF5000 on a drain that runs the length of our entire lanai (~40 feet)? And the covers do not come off, so we can't clean any traps (if there even are traps on lanai drains) that may be underneath. We've tried pressure washing into the drains, digging a bigger trench where it drains outside (to eliminate standing water); using a different (but obviously less strong enzyme), using gel bleach, using vinegar & baking soda. We still have the flies, and tonite after using the vinegar/baking soda again, hundreds of larvae came up out of the drains... yuck!

AWe have never really had this question and we are not exactly sure.  But our best suggestion would be to foam the drains with invade bio foam.  It is a microbial foam, like DF 5000 but in a foam, and is great at getting in all nooks and crannies where drain flies breed.  This would be our best recommendation.

QCan the DF 5000 be used to kill phorid and fruit flies?

A

DF5000 is not an insecticide and does not kill flies of any species. DF5000 is an enzyme product that breaks down organic matter that flies breed in. If the Phorid flies and Fruit flies are breeding in drains that have a buildup of organic matter, DF5000 is used it can help get rid of those pests.

If the flies are not coming from your drain then we do carry Natural Catch Plus Fruit Fly Traps that will attract and trap adult fruit flies flying around the room.  We also carry a product called Clean Air Purge which is an aerosol you can spray in the center of the room and it will knock down any adults flying around.
