I have been having problems with gnats in my plants, i have tried neem oil, insect killing spray, letting my plants completely dry out, systemic houseplant insect control, diatomatious earth, hydrogen peroxide, sticky traps, etc. nothing has worked and it seems as if that all just made them multiply?? they weren't bad until i did the systemic houseplant insect control and diatomatious earth and that just made them so much worse, they are all over my ceiling curtains, etc just everywhere. i'm honestly at a loss for what to do anymore
