A lifesaver was ready to toss all my plants! I tried several different things from those sticky pads (disgusting) to home remedies and nothing worked. Beneficial Nematodes - was skeptical, but let me tell you it worked so quickly it took me a little bit to realize I wasn't swatting gnats anymore.

I was pretty skeptical of these working to get rid of my fungus gnats. I have many many plants and nearly all of them were very infested. I tried all the remedies I could but nothing seemed to help. After getting these (was surprised at the tiny size of the package) and following the directions exactly, my infestation is nearly gone! I see only a couple of adult gnats on the yellow sticky things and don't have any flying around anymore. Very pleased!

My arrowhead plant gets fungus nats, they completely got rid of these until I repotted the plant, this is the second time I’ve ordered these, after the first treatment I don’t see any, but will treat for 4 weeks since the smallest bag has enough to do this.

Been battling fungus gnats in house plants for a few years. Tried everything suggested from home remedies to neem oil watering methods to adding a sand layer, letting plants dry out - nothing worked! Got my nematodes, applied exactly as directed, and wham - no more gnats! Literally no more! And I have about 20 medium to very large houseplants. I did apply twice within 2 weeks because I had enough left in my order. Would highly recommend - don’t waste time on any other method!!

These appear to have been highly effective against a fungus gnat infestation in our indoor plants. I tried several other solutions (letting the soil dry out, using sticky traps, electric light sticky traps, apple cider vinegar with dish soap, and mozzie bits/BTI) with varying degrees of success. While some methods did help slow the infestation, the gnat population still kept growing. The nematode approach has been by far the most effective. It seems to have hugely reduced the gnat population growth practically overnight. There are still a few adult stragglers, so I plan to repeat the treatment after a few days to remove any new larvae. There is enough in the provided packet for about 4-5 gallons of watering can applications.

I've tried other products like mosquito bits to get rid of some fungus gnats. While cheaper they just don't work as well. I was doing weekly applications for 3 weeks, and it helped but didn't quite do the job.One treatment with this stuff is all you need to get rid of an infestation. Make some "tea" out of this stuff and cover the surface of your soil.It's expensive, but it works.The shipping is quick, it's packaged extremely well with a reusable gel ice pack (I guess that's a "free gift") to make sure the product arrives healthy and ready to go.

I've only started using these a week ago and 90% of my fungus gnat problem is gone. I'll reapply once a week for two more weeks (4 total) to be sure to get all life stages and generations, but I'm SO impressed and happy at how quickly these took effect.

I have ordered this product 3 times and it takes about 4 days for the little guys to start working, but they eat my gnats every time!
