Review: My Plants Are Gnat-Free at Last! - I was very close to giving up on my fungus gnat infestation when I came across this product. It is a bit pricey, especially with shipping, so I hesitated at first—but I’m so glad I decided to try it. The nematodes arrived very well packaged with a cold pack. I unpacked them right away and stored them in the refrigerator so I could apply them that evening. One package ended up being much more than I needed for a single application, but I kept the remainder sealed in the fridge and was able to get two additional applications out of it before the expiration date. Best of all, I now have no fungus gnats at all. I also love that this is a natural solution, so I’m not spraying chemicals in my house anymore—and I don’t have ugly yellow sticky traps in all of my plants. This product was absolutely worth the cost, and I would definitely purchase again if needed.
Review: AbsoLUTEly worked! - I brought home a plant for myself from a local nursery that, unbeknownst to me, was infested with fungus gnats. I've never had them before, so it took me a while to figure it out. By the time I realized what was going on, the offending plant had infested my other 20+ houseplants. I tried Neem oil (does absolutely nothing for fungus gnats), and ordered the yellow sticky plant stakes as well. And while the stakes work for catching and killing flying gnats (and random house flys and getting stuck to my cat's underbelly), they do nothing to get to the root of the problem--which is destroying the eggs that the gnats lay in moist soil. I ended up laying as many of the stakes as I could horizontally over the top soil of my plants, as the gnats crawl over it and don't fly around all the time. This helped a little. But the Nematodes? At this point I would have to say the fungus gnats are eradicated! From 20+ plants! For the first application, I started with dry soil in all plants. I used a spray bottle to moisten the top soil, then followed the directions for the mixture of nematodes. I watered all the plants with the water mixture with a regular watering can. (I put all of the sticky stakes back over the surfaces). About 2 weeks later, I mixed up a more potent batch and transferred it to a spray bottle. I completely saturated the entire surface of each plant with the water. I have not seen one gnat in over a week. I can't even believe it. I still have about 390,000 nematodes left, so I may mix up one more batch, but I couldn't be happier.

### ⭐⭐⭐⭐⭐ The Only Thing That Worked for Our Fungus Gnat Infestation!
*by R***R on May 16, 2025*

After months of battling a relentless fungus gnat infestation, I am thrilled to say that these nematodes finally saved the day! We tried everything before: repotting our snake plants, drying them out, using sticky traps, and even mosquito bits. Despite all of this, the fungus gnats continued to multiply. We were ready to toss all of our plants out. We also tried a different brand of nematodes, but our problem only got worse. Feeling frustrated, we decided to give these nematodes a shot and I am so glad we did. We did two rounds of application, spaced 10 days apart, and I’m happy to report that we no longer have fungus gnats! Keep in mind that these beneficial nematodes only target the larvae, so we continued using sticky traps and zappers to catch the adult gnats. But after months of struggle, it’s amazing to finally be gnat-free. Highly recommend! The product is packaged and shipped with great care, it always arrives within two days after they package, and the nematodes come with ice packs that are still frozen to keep them alive, even in the hot Houston weather.
