In my Indoor Garden Whiteflies Fungus Gnats Thrips GONE
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 itโs 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. Itโs safe for red wigglers and beneficial insects and bees when used in greenhouse. I didnโt 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.

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

Super Effective at killing off fungus gnat larvae
I have been having a terrible fungus gnat problem in my basement grow tent for awhile now due to big box store soils, the included photo is a carnivorous butterwort that has been feasting on this infestation (as shown on the older leaves that are absolutely coated in them), I applied this product in some basil I have been trying to overwinter a few weeks ago, the fungus gnat infestation has been devistated since then, as shown on the newer leaves on the butterwort (virtually clean), this product does not get rid of the adult fungus gnats however, so you will still need a solution for that whether it be carnivorous plants, or sticky traps.

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

Looks Tasty
They honestly look like clear popping bubble toppings and are not dry. I applied them in random patches on a cloudy short rain shower day to kill cucumber beetles on my patch of about 100 sq ft of squash and melon that I grow on the ground. I didn't bother to water them again because they seem to already pre soaked on arrival. I am impressed to see that there are no more yellow beetles on my flowers the next day.

WORKED โผ๏ธ๐ฟ๐ชด๐ต๐พ๐ณ๐ฒ
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 โผ๏ธโผ๏ธ

Must use in the garden
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.

Product came wet
In the photos, dry granules are shown. My product came moist with liquid settled at the top, and Iโm 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.
