The Environmental Factor NemaKnights Slow-Release Nematodes - Biological Pest Control for Fungus Gnats, Thrips, & Whiteflies (280g, Treats Up to 50 Planters)

I bought this to help control my pill bug infestation. I saw a dramatic improvement after my first application, about a month later I bought another and applied again. Now my plants are thriving. It was easy to use, no discernable odor. Just sprinkle on the ground and water. This will be a regular seasonal garden maintenance chore as it helps to control other unwanted garden pests without nasty chemicals or damaging the soil.

Worked for me. Follow directions. I lightly watered plant..... I also sprayed a mist of distilled water over little beads to keep surface of the plant moist, for 3 days. I also used sticky trap for adult gnats as this only kills large. And I was very generous with application of the product. I would definitely purchase again ‼️‼️

Had a nightmare fungus gnat infestation, and in 4 weeks, not one gnat. An amazing product with no poison.

I have been using for 3 weeks with no noticeable effect Friggen gnats!!!

The nematodes work as part of a multi-step attack on those annoying fungus gnats. It has to be reapplied, which is fine, and takes months to really work well. But it eventually does, especially with other remedies I will explain. I had tried literally everything, every tip, trick, potion, oil, repotting dozens of plants a couple times (not fun), pebbles along the top of the soil, even baking soil in the oven to a certain temperature. The bake was early on a few years ago and my house smelled like a campfire. Yeah, I had used a soil with too much wood product. Learned more about soil after that lol. So tried the nematodes and have reapplied and followed directions. They lessened and it took many months, but I still considered it a win. After decades of houseplants with never EVER having gnats, these fungus gnats now seemed unavoidable and I couldn’t figure out how to finally be rid of them. This product helped, along with bottom watering those plants that respond well to that type of watering. Using the nematodes, over time, has lessened the gnats. Adding both yellow sticky traps and a couple socket bug zappers (small that plug in at the electrical socket - bought a pair of zappers inexpensively along with the yellow sticky traps here on Amazon) have made the gnats ALMOST gone. All three have worked the best, together. At this point, the sticky traps gauge if gnats missed being stopped by the nematodes and bug zappers. If I have gone weeks with a clean yellow trap, I consider that success. They used to literally be loaded with gnats. Eww. Now I can see a couple gnats a month on the yellow traps. Some plants’ traps have none. The one for the money tree in the photo now catches more cat fur as there aren’t many gnats.😂 So I’d say this nematode product does work if used as directed and one allows lots of time. The other added items, for me, seemed to help a lot. Using any of the three alone likely won’t make a huge change (from my experience). This is why I rated 4 stars, as it could not eradicate them alone but do as part of a plan! Good luck!

My asparagus garden was overwhelmed with Asparagus Beetles. Thanks to NemaKnights, I now have a healthy, thriving patch.

In the photos, dry granules are shown. My product came moist with liquid settled at the top, and I’m not sure if the product will be effective. Im in Florida, so maybe the heat and humidity got to the product before it reached my house. Easy to use. Easy to apply. Mine came with a slight smell when I opened the top. Maybe the directions should make it clear what for product should look like upon arrival.

I have always had a green thumb, but haven't had indoor plants in a LONG time due to having a cat, well...since my cat passed, I decided I NEED to get back into my love for plants.....then fungus gnats UGH...how...why? I tried everything, neem oil, hydrogen peroxide mix, Dawn dish soap, yellow sticky traps....but nothing really made a difference until I bought these!!!! It has been about 1 month since original application and those little buggers are about 90% gone....will continue to apply but am VERY happy with the results.

Useless product, more bugs in plants then before bcos of it’s moisture, absolutely no use,

Not bad
