MICROBE-LIFT BMC Biological Mosquito Control, Liquid Treatment for Medium-Sized Decorative Water Gardens Up to 2,000 Gallons, Fountains and Ponds, 6 Fluid Ounces

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.

Highly recommend. This product works! This is a bioinsecticide. A Larvicide (Bacillus thuringiensis) or Bt, and acts on the larvae of insects. Very concentrated. Larvae eat the bacteria and essentially die. It has a short life but works very effectively to control mosquitoes and fungus gnat larvae. You need to use this product regularly to break the life cycles of gnats and mosquitoes as they constantly lay eggs that hatch into larvae. This product kills larvae only, not eggs or adult insects. I initially bought this product initially to control the fungus gnats in the peat moss and planting mixes that I used for my seed cell transplants. Most of these products are contaminated with fungus gnat eggs. To prevent gnats, I add a drop of Microbe Lift BMC to my water container each time I water. I grow indoors and did not have a single gnat flying around. I plan on using this product in my bird baths, fountains, flowerpots, and anything with standing water to help control misquotes in my yard.

Last year I had an awful fungus gnat problem. I was ready to kiss my plants goodbye. This product does a great job at eradicating the larvae of that dreaded fungus gnat. It is part of my triple threat treatment to control them. It must be continued periodically as instructed for adequate control.

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.

I regret purchasing this product. It has caused me to have to reset the pond twice. I followed the instructions carefully as I am wary about my water quality but also really wanted the product to work. Unfortunately, if anything it appears to encourage mosquito larvae. It also turns the water extremely murky and rancid smelling, and leaves a nasty coating at the surface line. Once more I have to empty my pond and try to wash off the residue. Thankfully I did not have any fish in this pond, but if I manage to restore the water quality I had, fish is probably the better way to go for mosquito control. It seems that it works great for other people. Perhaps the bottle I received has been exposed to unsuitable conditions on its journey here? Amazon gave the option to return faulty product so at least there is that.
