How many times til you saw a difference u mentioned about a week between drenches
I saw dead larvae coming out in the run off immediately. Three drenches stops all of them dead and the yellow stickies will control the flyers that lay the eggs.

Good luck.

I have sand i bought from lowes it has small rocks in it bot sure how well its wrking yet its only been about 4 days
You'll still notice them flying around for about a week or so.. as long as they don't have access to decaying organic matter they'll dissipate soon as they die off naturally.

Again though, id use that in conjunction with watering from below if that is feasible. The very top layer of your soil (and the sand) will remain dry, further creating an unfavorable environment for the gnats to live/breed in.
 
Mosquito Bits contains the same ingredient, BTI........it's just not as concentrated as Gnatrol.
Hey buddy got the stuff in the gnatrol. So I haven't watered my plants for some time because I wanted them to dry out b4 the gnatrol..is it okay to mix in my nutrients with poison or would you do the poison by itself?

I mix it in with my nutes, but I grow in coco so I feed daily.....I never give it plain water. It won't change your pH.......and it's not poison.
Good luck.
