When I've caught more than a few gnats I mix up 1 tbsp/gal of gnatrol, pour a few cups of solution on the soil in each pot, enough to wet the whole surface pretty well. The instructions say that 3 applications a week apart is best but a single application really hammers the population, beats 'em down to nearly nothing.
They went nuts on me the first time they showed up because I futzed around with dunks & bits. When I stepped up to gnatrol then gnats became just an occasional nuisance. It's pro grade stuff-
