I was plagued with fungus gnats for months until trying this product. It wasn't clear to me how long it would take to work, however I was able to test it's use on 2 plants with active fungus gnat infestations. It seems to have worked within a few hours of application. The two plants I tested were 100 free of fungus gnats within 24 hours. I'm still pinching myself and going back to the plants, knocking them around and digging in the soil expecting to see at least a few! THERE ARE NO FUNGUS GNATS :DI also had a mild issue with the gnats in my hydroponic grow area. Despite switching to leca, the gnats somehow found there way in (and LOVED hanging around my sprouts). I sprinkled a diluted solution on the leca and grow mats and haven't seen them since. I didn't believe there could be a fast acting solution for this. If you're struggling with this issue forget all other methods - for weeks I used a combination of diatomaceous earth, Sevin, hydrogen peroxide, drying the soil....NOTHING worked and they persisted until trying this.

Mosquitoes were not big fans.

I add a bit from the tabs to my plant water to help kill the fungus and gnats. this and the sticky tabs are great!

Easy to use and worked miracles

USED ALL SUMMER..NEVER SAW A MOSQUITO!

We had misquito larvae in our tiny little pond, and I did not want to use chemical insecticides. This uses a bacteria that kills the larvae and leaves the fish alone. that's the way to do it.

These work very well and are long lasting.

These are a great product to use. I put them in my little fountain where mosquitos like to breed in the summertime. They're easy to use straight out of the package. I would buy them again.

I had a break out of fungus gnats in my indoor house plants. I tried repotting my plants and using the sticky traps, but they came back. After reading up, I found these. I put a quarter of a disk in a gallon of water and water as normal. I noticed a huge difference after a week and they're basically gone after two.

I grow plants indoors and have a terrible time with gnats. I tried all kinds of sprays and sticky traps. A lady at the store told me to try these and afterwards I finally noticed the gnat population subsiding

I purchased this product when I first got into plants and bought new soil for my fiddle leaf fig tree. I had read horror stories about certain soils producing fungus gnats and the person I spoke to at the plant shop told me fungus gnats are inevitable so I bought this as a preventative measure. I dropped half of one into a gallon jug of water and watered my plant with that water. I've used this since September and so far, no gnats! Hope it stays that way!

Great product for standing water

Been using this for years, mosquito's gone by next day.

I bought this for my fountain in the side yard after noticing mosquito larvae floating around the lower tub.I inserted 1/2 of disk in the pump compartment area which is lobated in the mid pan support in the lower bowl. I inserted there in lei of throwing in the fountain because I have dogs and didn't want them eating it.one disk treats 100 sq feet, my fountain is mid-size of that. Not sure how long the treatment lasts since its been only 3 weeks and the weather is changing to fall. I would suggest keeping an eye on the lower basin of a fountain or the pond for larvae, disk dissolves in a couple of hours.

I had a problem with mosquito's in my birdbath and thought I would give this product a try. I only used about 1/5 of the tablet and I have not had any new mosquito larvae since. The birds don't seem to mind as they still come every day to drink.

The only down side, is after a bit, of being in the water, it starts to breakdown, and can make a mess... perhaps, i just need to replace it more often, before it gets to that point!

I wanted something reasonably priced that would do the job, without harming any of the other critters. Glad that I found this product.

Easy to use. Does the job exactly as expected.

No more mosquitoes

I struggle with gnats each year when I bring my outside plants inside. This year, I decided to try treating the plants with these. I broke them up and soaked 1/4 of a ring in warm water. They don't dissolve all the way, but they still work. I treated all my plants with these, and I've only noticed 2 gnats in the past 2 months!
