Review: Amazing! - This is incredible! It saved three of my dying, contaminated plants! I was about to give up and throw them away, but I'm so glad I found this product! I just wish it came separated into smaller containers so I could use it longer.
Review: Results as promised. - We developed a fungus gnat infestation after bringing a few plants in this fall. They happily reproduced and colonized all of the other potted plants in the house. I couldn't even look at my computer screen or phone without getting one in my face. We (and our guests) put up with it for months. We dosed each and every plant in the house and followed the application and watering directions on the label, and poof! It took three days... didn't see another gnat for a month. The plants are happy and healthy and I'm pleased to be writing this in the warm glow of a bug-free screen.

### ⭐⭐⭐⭐⭐ Amazing!

### ⭐⭐⭐⭐⭐ Results as promised.

We developed a fungus gnat infestation after bringing a few plants in this fall. They happily reproduced and colonized all of the other potted plants in the house. I couldn't even look at my computer screen or phone without getting one in my face. We (and our guests) put up with it for months.

### ⭐ Didn't work, not alive
*by C***C on May 4, 2025*

I got these to control thrips and fungus gnats. It does not work for either one. After multiple applications over several weeks, the numbers are not reduced, there are still new thrips emerging from the soil unharmed. I don't think there were any live nematodes in this, maybe it got too hot, maybe it was too old, I don't know, but there was nothing alive here. They did absolutely nothing. All the bugs they supposedly target are thriving after weeks of repeated application and careful nurturing of the soil so as not to harm the nematodes. Stopped by to write the review because I am back here searching for something that actually works, because these codes do not seem to be alive upon arrival. PS, I've been keeping the open container in the fridge, the beads are still moist, everything appears normal except there's nothing alive to infect, or so it appears. This is an indoor and controlled environment, I don't think they're alive.
