Figure I’d post this, This way I show how things can get out of control real quick. And how I deal with it. Anyways, I’m having a fungus gnat issue. For some reason I’m my 2x4 the back right hand corner pot is infested with gnats. Same pot or corner that I always have issues with. I think the air is stagnant back there so I added a small fan blowing down there straight to that corner and put out my yellow sticky traps. Also have fly traps by my lights work great for gnats. I did try knocking them back a bit with hydrogen peroxide and water 1 parts to 4. My wife used it last time and she liked the results so I had to try it.
