Gnatrol is pro-grade fungus gnat control. In soil, a single application at 1 tbsp/gal of water beats them down, hard. I just thoroughly wet the soil with the solution. I like to mix it with ewc tea. Per the instructions & my personal experience 3 applications a week apart will deal with even a very heavy infestation.
I'll never eliminate them from my organic soil grow because they ride in with worm casting & compost. I let them get out of hand once a couple of years ago & won't let that happen again with gnatrol on hand.
