ECOLOGICAL LABS MICROBE-LIFT BMC2 Biological Mosquito Control, Liquid Treatment for Decorative Water Gardens, Fountains and Ponds, 2 Fl Oz

After trying various methods of eradicating fungus gnats on my houseplants, including mosquito bits, which did nothing, and hydrogen peroxide, which worked at first but not for long, I saw a recommendation for this. The first time I used it I put new yellow sticky traps in all my plant pots to monitor the gnats. Three weeks later they were still all clean, absolutely zero gnats on them. I thought it was the stickies not working. But I haven't seen any of the annoying little blighters since that first treatment. Well worth the price as one drop diluted in water did my whole collection twice. Great stuff.

The seal was broken when received. I decided to try anyway, and after 2 weeks of consistently using a minuscule amount of product when watering my houseplants (1 drop per 2.5l) I am fungus gnat free. All gone.

You won't beat this.. I had a bad gnat problem6 drops of this in 8L water.. literally the next day gone, I could only see one hanging on for dear life... Now! nothing..

Arrived unsealed. Returned

I read reviews so I thought it would be the best thing for house plant flies (fungus gnats) so I tried it and it did nothing to kill the tiny worm-like larvae that turn into the gnats.

The latest batch of mosquito dunks I got doesn't seem to work because I had mosquito larva in my outdoor water tanks. I got this stuff for fungus gnats in my sensitive houseplants, and when I noticed the mosquito larva outside I decided to mix some of it in. I took a sample of the water a day later and all the mosquito larva were dead, so it clearly worked better than the bad batch of mosquito dunks. On a cost basis it's cheaper per gallon treated than the dunks too, although not visibly "treated" to your neighbors as a floating dunk. I'll keep buying this and using it, and just use the dunks to make it obvious to the neighbors that my stagnant water bins (I keep it for the frogs) are not breeding mosquitoes so they don't call the city on me.As for the original reason I bought it, it wiped out the fungus gnats. I mix it with distilled water (tap water has chlorine which kills the good bacteria) and soak the soil of my houseplants. A little bit goes a long way because this is very concentrated. Much easier to use than soaking mosquito bits in water and then skimming them off to use the water as a soak. Overall I'm very happy with it.

Absolutely a key item in my pest control arsenal! I ended up with some contaminated potting soil, did not know any better, got an infestation of fungus gnats. I tried tons of stuff, natural remedies, some chemicals, even mosquito bits. Come to find out, it was that new bag of soil I had stored... smh... So after finding the main source, it was time to try to deal with the affected plants (Everything?!?!), and that is where all my real problems came about. I could not get rid of them. Ended up killing off a bunch of stuff, trashing the entire set up.It happened again, but I caught it and this is when this product came into play. Very soon after I started using this (and yellow sticky traps), I noticed a reduction within days. And now, I very rarely see a bug and even if I do, I am confident they will not be hatching any eggs and I will likely catch the adults on a trap or with my spray.The problem is pretty much nonexistent. I am so confident in this product I started using it outside too.Things to keep in mind... It works really well and is super concentrated. It does not take much to get the job done. I found out later I had been overusing it, smh.I have some plants using wicking ropes. I simply add a small drop of this to each of the water containers and it seems to be able to wick up just fine and soak into the pots...As far as small-time use, lol. This is a great value considering how much you actually should be using verse how much you get. Amazing grab! I am not sure yet if this stands when you scale up, but for a home gardener or someone with just a few plants, this is totally worth every penny. A drop per gallon basically, com'on, unreal! and that may even still be overusing it, lbvs.Internet says it won't kill the worms!!!!I totally recommend this product and will be faithfully using it for most thing related, where possible.

Much easier to use than the granular disks which leaves stuff floating in the water to clog fountains,

I am so grateful, this Finally took care of fungus gnats! I tried so many things for a year - getting rid of plants, repotting plants, sticky traps, apple cider vinegar, diatomaceous earth, nothing was working and it was so bad that my husband was swatting gnats while on work zooms & his clients were asking if he was OK.All of my favorite plants were infested because I took a bonsai outside for some sun one day…. Huge mistake.What finally worked was this product, in combination with the yellow sticky traps from Amazon.It did not take just 3 weeks though, I read reviews here thinking it would be taken care of in 3 weeks, but it was more like 6 weeks.So be patient, and put a very strong squeeze/stream of these drops into your indoor watering can & fill with water; and then let it sit for 30 minutes. It really helps if the drops can develop in there.Every week I would do this, once a week- make sure not to overwater the plants; that causes gnats.I watered every single house plant, and have 1 to 3 sticky traps in each plant, and finally after 6 weeks we have no more fungus gnats. I’m still going to use it until all the drops are gone, which should be another 2 to 3 weeks.Thank you!

As far as I can tell the Microbe-Lift works great. I use it in a fountain, so having a liquid instead of a doughnut or bits works the best not to clog the pump. I contacted the company and was told it is good for 3 years if kept at 72 degrees F or less. The manufacture year and month/date code is on the outside packaging container. I don’t want to be a mosquito farmer, so I can’t live without this form of BTI!
