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

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.

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.

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 bought this to kill fungus gnats and I'm happy to say it works! I think I've tried everything, even nematodes on ice, nothing works as good as this. Its a different strain of BTI or something, idk .. this stuff will kill every single fungus gnat, it breaks the cycle, I'm finally gnat free!

I found this on Amazon after someone linked it in a forum. I'm so glad I did. My only regret was waiting for over a week to use it. If you're dealing with gnats, no-see-ums and others, just get this and spray at the source. I noticed a difference within a couple days but after a week, the difference is huge. It comes with a measuring cup so it's very easy to use. It mixed very well and worked well with the sprayer, saved money from paying a company, the packaging is very good. I'm glad I found this on Amazon.
