I give up
I have done everything except change the soil in these plants to get rid of the gnats. Granted they arent as bad as they were a few months ago, but they still exist and its annoying. They seem to favor the peace lily. This isnt an issue of overwatering or the plant being too moist because I just let the become dry as a bone and they are still hanging out. @$&!:$&@!!!!!!!!
