I have used these in a number of ways, but my best results cake from soaking a few in a monkey dish then pouring directly into the plant at the surface. Soaking in a full bowl or dish of water, with the plant inside also worked well. It takes time and repeated treatments, but it has helped my fungus gnat problem immensely. Will purchase again. I now use as a preventative. No smell, and completely pet safe. Easy to use.

Seems to work. Earwig population definitely drops a couple weeks after application.

I tried this with great reluctance because nothing stopped the invasion of whiteflies fungus gnats and thrips back in May when I bought it and sprinkled it on the top of the hydroponic reservoir of the hydroponic tower and I sprinkled it on top of the soil of plants in the grow room and covered it with 1/2 inch of soil mix and watered it in and bugs DEAD. And it’s three months later and no bugs and my yellow sticky traps are still free of a bug. I add more to the hydroponic reservoir after flushing it out and adding new water and nutrients and PH adjustments and EM1 I always add. I will keep using it with plants in my house. I switched to Miracle Grow Seed Starter Mix to prevent bringing in pests in my basement seed starting station. I make sure I brush my hair and clothes off before entering the house and I have a yellow trap by the door and above my kitchen sink I have basil as a trap plant and yellow trap. Yellow traps by the basement grow room entrance middle and exit. It’s safe for red wigglers and beneficial insects and bees when used in greenhouse. I didn’t bury it 1/2 inch and only sprinkled it on the soil surface and watered it so white flies had other ways to live but it killed fungus gnats and thirps dead in the greenhouse. I am finding success with Arber organic insecticide so far to kill whiteflies but in the greenhouse Nemaknights is my go to for soil management of pests.

Does not do a single thing. Waste of money. Caused my soil to mold

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!

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 ‼️‼️

I follow the directions but the fungus gnats are still pervasive in my house. Others have said that Amazon might not store this product under controlled conditions which could diminish it's effectiveness but I don't know and I don't have a microscope to check if the nematodes are alive.

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

Not bad
