MICROBE-LIFT BMC Biological Mosquito Control, Liquid Treatment for Medium-Sized Decorative Water Gardens Up to 2,000 Gallons, Fountains and Ponds, 2 Fluid Ounces

I've been using this Biological microbe based Mosquito Control for fungus gnats in my houseplants. Ever since beginning this protocol, I have seen very few gnats in years. I LOVE this stuff! It is super easy to use, you just add a drop into the water and give it a light mix, then water plants. It has lasted me for years so is well worth the cost. Once plants are watered, there is no additional smell from this product. It works great! You just can't beat this if you have fungus gnat issues.

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.

I feel as though we've had fungus gnats for 45 years. This did it, period. This did it. No sticky paper helps if they have taken up permanent residence. This did it.

These drops do work to keep the tiny gnats down to a minimum. You do have to use them regularly. I skipped a few waterings and began to see more gnats. Playing catch-up now.

The microbe-lift mosquito control liquid treatment was a good purchase, inexpensive and has shown to be very effective in quick reduction of mosquitos in our pond area. We have had not negative reactions to our fish or plants but have seen a reduction in mosquito and no larvae found in filters after 7 days. So far, the liquid has no odor, safe to usage and the duration of action could be longer. I will use it with my mosquito donuts to maintain mosquito control.

Update: I wanted to love this product, but it does not work. The gnats in my plants grew more and more out of control until I decided to go back to Mosquito Bits. They are messier but they work. The gnats were reduced by 90% after one week/dose, and down to 95% after the second. I'll use for a couple more weeks until the gnats are gone. I've been using Mosquito Bits to control fungus gnats in my houseplants for several years. They work well but require soaking, straining, then disposing of the bits, which is time consuming and messy. And it can be hard to guage how much to make to water all of my 60 plants. These drops are so much easier to use. I put 1 or 2 drops in a gallon of water, then water the plants. No soaking, no clean up. If I need more I make another gallon. I've used them for two weeks and immediately reduced the gnats to just a few caught on my sticky traps. I will use for a few more weeks to be sure to break the entire life cycle. I will use on all new plants and new soil. I got the small bottle because it appeared to come in a dropper bottle (inside a plastic jar), even though it cost more per ounce. Convenience is worth the price. This bottle should last a long time even if I use it every week. Absolutely recommend to all indoor planty people.

I used this for fungus gnats and it worked. The liquid is much more convenient than soaking dunks and it's nice to get a tiny bottle instead of a huge amount. It takes a while because of their lifecycle. Follow the directions on their website pond product FAQ which says 2-4 tsp/gallon weekly.

I'm using it 1 drop per gallon to water my indoor plants to see if it helps with the gnats. I've used it twice and it does seem better but hasn't eradicated them yet. I'm hopeful with a few more times watering and will update my review to help others with same issue.

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 problem 6 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.
