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.

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..

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.

Arrived unsealed. Returned

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.

Fighting gnats around your house plants, this is the key. Got rid of all our gnats.

I’ve been using MICROBE-LIFT BMC2 Biological Mosquito Control in my backyard pond and small fountain, and I’m genuinely impressed with the results. Within a couple of days of applying it, the mosquito larvae were completely gone—and they haven’t come back since I started treating regularly. What I really appreciate is that it’s a biological solution, using a strain of *Bacillus thuringiensis israelensis* (BTI), which specifically targets mosquito larvae without harming fish, birds, plants, pets, or beneficial insects. That peace of mind is important to me, especially since I have koi and some visiting pollinators near the water. Application is super easy: just a few drops based on the water volume, and you’re good to go. One bottle lasts a long time, making it very cost-effective. There's no odor, no mess, and no disruption to the ecosystem—just fewer mosquitoes.

Shocked by how quickly this worked - I used on ALL of my houseplants at once (~30), even though a few weren’t ready to be watered yet. For them, I made sure at least the top couple of inches were sufficiently soaked, apologized, and stuck them in front of a fan and grow light. The rest got a thorough watering. I also splashed a tiny bit into my prop jars and any pebble trays, to make sure I’d covered all my bases. I most definitely overdid it based on what the instructions said, but since it worked, fyi - I used 2 drops per IKEA 1.2 liter watering can refill. Note - this stuff was STANKY when I first opened the container, but thankfully, once diluted in water, no obvious odor. So don’t throw out the plastic outer canister - you’ll want to keep the bottle of liquid in there to contain the smell. I stopped seeing gnats the same day I first treated. I hadn’t had a terrible infestation to begin with, but before, if I gently jostled a plant, I’d usually see one or two fly around or crawl up from the base. But after this treated water, nothing moved when I tapped the stem. About 8-10 days later, I saw maybe 2 gnats in a particular plant who was probably not drying out as well as he should be, but I watered again with the drops and haven’t seen anything since. So I do think consistency (aka every time you water) and making sure all plants are treated at the same time (so they don’t just hide out in the next plant) is key. I’m so grateful I tried this stuff, I highly recommend for anyone with houseplants. It’s got a higher concentration % than BITS, fyi.

Doesn't work like I thought it would.
