What’s everyone using for gnat control ? I have stickies ...

I had an emerging problem, but it's good to remember that gnat larvae need continuous moisture so letting my soil dry out until the plants could tolerate it helped. I would also sprinkle cinnamon on top of the soil. Enough that you could see it, be generous if you can. I had some sticky traps for the adults that flew around. I would also spray down the surface of the soil with a 60/40 part mix of 70% isopropyl alcohol to water occasionally. It's been a few months and I haven't seen any anymore.
I'm using yellow sticky thingies and they've helped me greatly, although a couple of these little annoying creatures still casually fly around here and there.
My mother-in-law tried another method (besides sticky sheets): she removed the top layer (not much, like, 1-2 cm) of soil in each pot and replaced it with fresh soil. And now, she says, she hasn't seen any gnats for a while already!

All very good suggestions. @Moonbloom hit the nail on the. You have to disrupt the life cycle. That means ya gotta kill the eggs, larvae and the adults. I found I needed to be diligent and patient more than anything.
I'm using sticky traps in all of my house plants and using a hydrogen peroxide and water solution once a week. I chose that one because the article I read says HP kills all versions of the fungus gnats, even the eggs. It seems to be working. The plants were immediately perkier after the first drench. And now the ones that were more badly infected are also using water better (drying out more quickly).
