Gnat fly infestation

So about 3 weeks into the grow I started seeing gnat flies. So immediately put up some sticky traps in the planters which have helped. But also bought Scientific Nevada science product 203 concentrate which I read works great for gnat flies and is organic and was approved by Nevada board on medical marijuana so totally safe for use. But not sure how long it'll take to wipe these guys out or if there's anything better I can do. I just watered my plants after 5-6 days no water and used as instructions stated per gallon for soil drenching and then before lights went out sprayed the foliage with a different mix ratio per instructions for spraying. I get home today and still having an issue, and it's probably me being impatient haha any ideas?
