It works! When you are battling an infestation, you just sprinkle them on the top of the soil and gently mix in. It’s about week 4 now and I can say I haven’t seen a gnat in several days.

I have a larger collection of plants and my biggest issue routinely is fungus gnats. Apply about every 4 weeks. I saw the mixed reviews but decided to give it the benefit of the doubt.
