The Drain fly kit used to come with DF 5000 drain gel. We now are placing InVade Bio Drain Gel due to customer demand, performance, and it is more economical for our customers. The video instructions on this page apply to any gel even though DF5000 is used in the video.
The Drain Fly Kit with Invade Bio Drain Gel will treat up to 2 infested drains and includes On Time Insecticide Aerosol to control nuisance flies during the treatment process, and a pack of 12 Trapper MAX glue boards to monitor infested drains. On Time Aerosol will shoot out in quick misting spurts that will allow you to spot treat around sinks and drains and in open areas.
If you have drain flies in a master bathroom with 4 drains (ie; 2 sinks, tub, and shower), you would need 2 drain fly kits. One bottle of Invade Bio Drain Gel does one drain for one week.

The Drain Fly Kit with InVade Bio Drain Gel will treat up to 2 infested drains and includes On Time Aerosol to control nuisance flies during the treatment process, and a pack of 12 Trapper Max glue boards to monitor infested drains. On Time Aerosol will shoot out in quick misting spurts that will allow you to spot treat around sinks and drains and in open areas.
Drain Fly Kit Instructions:
1. First, you should cover infested drains with the included glue board traps. You do this by folding the boards in half like a tent, and then peeling off the plastic film on the glue. Place the glue board over each drain at night that you want to monitor. The board should sit slightly up off the drain (as shown in the image below), allowing air to move into and out of the drain. This will allow you to (1) determine which drains are infested by drain flies so you can focus your treatment in the right areas, and (2) monitor and control infested drains during treatment by catching adult flies that exit the drain. If you are treating a bathroom, you should place one glue board over the sink and one over the bathtub drain. Tip: After each night, circle caught flies with a marker so that you can see how many were caught each day.
2. Pour 4 oz. of Invade Bio Drain Gel down each infested drain every night for at least 7 nights. DO NOT rinse the drain with water right after applying the Bio Drain Gel -- you should let the sink sit all night without being used. Cover the drain with a glue board (see step 1) during the night to catch any escaping flies.
3. Use the On Time Aerosol to lightly mist around infested sinks to kill nuisance flies during treatment.

Drain Fly Kit Review
By SI on June 21, 2010

Although the Drain Fly Kit helped reduce the number of drain fleas, it did not eliminate the problem. The Catchmaster sticky paper does help locate the source of the problem though.

Drain Fly kit
By Kathy on December 27, 2010 Verified Purchase
The sticky paper showed us exactly where the problem was - not actually in the sink drain but where the drain pipe goes into the floor - never would have guessed. The spray kills instantly - great! Don't know how much the green drain cleaner works as I am too big to fit down the sink drain. All in all - a great product. Thank you, Katy

Worked well
By Lou on November 17, 2010 Verified Purchase
I used the DF5000 but the Drain Flies were still present after a week. My wife noticed that they larvae were coming from tiny cracks in the grout on the shower floor. I spread some of the DF500 on the floor and used a brush to clean the grout well and let it sit overnight. It has been two weeks now and have not seen any Drain Flies. I used the DF500 and the glue pads, but I did not use the spray. You may not need the spray if you do not have a great deal of flies.

Mystery Flies taking over Cape Cod Bathroom
By Obrien on September 20, 2010 Verified Purchase
Mystery flies replenishing themselves every day. Yuck! We called our professional pest control person and he did not have a clue what type of insect they were or how to get rid of them. We looked on-line and found your description of our drain flies and your excellent product and we had our problem solved in 2 days. Thank you so much for your great service, prompt delivery and easy to follow directions. We educated our pest control people on the nasty drain fly, or 'mickey mouse' bugs.

They Are Gone!
By Barbara on August 18, 2012Well, we bought the kit and found the flies were coming through the overflow in our bathroom sink. No amount of this stuff would get rid of them. :-( We were in the basement and noticed that our dehumidifier was not draining correctly and had filled up. We inspected the tube that went from the dehumidifier to the drain and found our organic matter and source of the flies. We got rid of that tube and coated the new tube with this orange stuff and we have been fly-free since. We are going to maintain that tube with this orange stuff from now on. Just be careful with the orange stuff as it does stain.

Drain Flies Go Away
By Ali on August 8, 2012I wish I could say it worked. But it didn't. I followed the you tube video on how to use the drain fly kit and I have not been successful. I still have at least 5-8 drain flies flying around in my shower every day. I am not sitting with all this extra product because I bought double the amount. I am not sure what to do now.

Drain Fly Kit
By GR on June 27, 2012I can't speak to the kit except that the spray was for a timed device which was not part of the kit. Plenty of sticky mats were sent. I gave it to tenants to use, so I can't speak to whether or not they used it as directed, but the online video is excellent. It arrived very quickly. I will order again if needed. The only reason for 4 stars instead of five is the spray.

drain fly problem
By Emily on May 31, 2012This product seemed to help our problem we were having with drain flies. We were seeing them before treatment and during treatment, we saw one. We haven't seen any since the treatment period ended. Would recommend this product to someone having the same problem.

Drain Fly Kit
By Nancy on February 26, 2012Wonderful. The glue traps are a stroke of genius - helped us isolate the problem - a shower drain that we don't use.We didn't have to waste material on drains that did not have a problem. We treated the troublesome drain and haven't seen a fly since. Thank you.

It works really good
By Mark on August 22, 2011I had tons of drain flys and tried some other home remedies that didn't work. In 3 days with this fluid they were no longer hatching. One thing I did to get rid of the ones flying around was take a small plastic container and mix 1 part water (1 cup) with 1 part (1 cup) apple cider vinegar and a a couple drops of dish soap (which keeps the surface from getting a film). They are attracted to the smell of the vinegar and drown in the container. We caught probably 100 in there. My son also rimmed the inside of the container with dish soap as he thinks they slide into the water/vinegar better. I preferred this method to killing the flies vs. the spray bottle stuff in the kit. We had flys mostly coming form the disposal side of our sink but also the other side fo the sink so I put the DF50 in both sides. The bottom line though is you have to keep new flys from hatching and this stuff works for sure. 3 days is pretty good!

QI am wondering how to attack my drain fly problem first.
I have drain flies in the kitchen (where I first saw them 3 years ago), and now have them in both bathrooms. I wonder if they are behind the kitchen cabinets, too(?). We had a flood in the kitchen area 4 years ago. Not sure if that's related. Could they spreading to the other drains? We also have a floor drain (our kitchen is on the walk-out basement level) and wonder if I should treat that, too.
AAll drains in an infested room must be treated. Drain flies can definitely spread from one room to another and drain flies can breed anywhere there is a buildup of moist decaying organic matter as that is all they need to breed. We recommend that you check out our Drain Fly Kit which comes with all of the products we would recommend to treat a drain fly infestation plus it comes with a step by step instruction guide to help you through the process. You can also watch the instructional video on the Drain Fly Kit page on our website (scroll towards the bottom of the page to read our instructional guide). If after following the inspection instructions on our drain fly page you find that the flies are not developing in the drains you may need to find a way to get behind the cabinets and thoroughly clean the area you suspect is infested.

QIs the DF5000 safe for the plumbing pipes? They won't cause any erosion over time will they?
AThe DF5000 in the Drain Fly Kit are not corrosive to plumbing pipes whatsoever. The drain fly treatment products are actually a bacterial formulation that are only effective on organic matter built up in a drain and will not eat through metal, polyurethane or any other type of plumbing pipe.
February 19, 2010Joyce asked:
QI own a three apartment buildings. Do you recommend I use the drain fly kit in all apartments at once?
I own a three family apartment building, do you recommend that all three apartments use the drain fly kit at the same time? Do you give discounts on multiple orders?
A Yes, we do recommend that all drains in any infested area be treated at the same time. If drain flies have been observed in all of the units, then all of the drains in all of the units should be treated with the DF5000. Please call us if you have a large order to discuss discounts. We are currently running a promotion for $5 off of your second order of $50 or more.(You will recieve an email with the coupon code after your first order) And don't forget, by purchasing the drain fly kit you are already receiving a great discount and we always offer free shipping.

QWhat chemicals can we use to repel and eradicate leeches?
Lots of small leeches coming out of my bath room drain.
A Have you had these pests actually identified as leeches? Are you seeing small moths or flies in your bathroom? Usually small worms coming out of the drain indicates drain flies. We recommend that you take a few moments to google 'drain fly larvae' and see if the pictures correspond with what you are seeing in your drain. If the pictures do correspond with what you are seeing there a few things you should do. Drain flies breed and lay eggs in areas where there is decaying organic matter such as bathroom drains. To start the process of getting rid of this pest you must thoroughly clean the drain where the worms have been spotted. Next you should apply a product called DF 5000. The DF 5000 drain fly gel will coat the inside of the pipe and will help breakdown built up organic matter. This process must be repeated every night for 5-7 days. In pipes where there is a lot of built up organic matter a second week long treatment may be needed. If you have spotted adult drain flies in your home you can spray a product called Clean Air Purge III to help eliminate these breeding adults. You should place glue boards over each drain in the bathroom to capture any flying adults entering or leaving the drains. Using glue boards also helps monitor the level of infestation. We have all of these products combined into a Drain Fly Kit for your convenience. If these pictures do not look like what you are seeing you must have the insect identified so the appropriate treatment can be recommended. You should contact your local Cooperative Extension Office and ask to speak to the entomologist on staff. The entomologist will tell you how to properly collect a sample for identification purposes or he/she may request a picture.

QCan this product be used in a toilet bowl?
I came home from a 10 day vacation only to find drain fly larvae (about 20-60) in the toilet bowl of an upstairs bathroom that is seldom used. I did notice a small fly in the hall by this bathroom before going on vacation, but didn't think anything about it. Of course, I was very concerned when I saw the surprise waiting for me upon my return. Following my first instinct I took a picture of it & then flushed the toilet. I also flushed bleach down the toilet. I haven't seen any more flies, but I don't want to take any chances. Could they be coming up from the toilet drain or did they just lay their larvae in the toilet bowl (due to the stagnant water)? Prior to this event, I hadn't noticed any flies in other areas of the house. I want to put an end to this before it gets out of control. Please advise!!!
AYou can use DF5000 in the toilet bowl and in the toilet tank. Most likely the flies were introduced from outside and did not come up through the drains. Be sure to scrub the toilet and then add the drain gel. Let sit over night and flush. Repeat as necessary.
November 28, 2012Joe from Westerville. Oh 43081 asked:
QDrain flies disappeared
I bought a "kit" about 3 weeks ago. Once it arrived, i didnt open it because the flies have not shown up for about the same 3 weeks. Are they gone or should i still do the treatment? Also it's been cold lately in OH, would that effect their activity?
AIt is possible that the drain they were breeding in cleared of the organic matter the needed to survive. Only time will tell if they are gone for good. If the drain/pipe hasn't been cleaned in a long time it is still worth your while to go ahead and clean the drain with the drain gel to avoid this problem in the future.
