I've tried the vinegar, dawn and water solution and I let the soil dry to 2 inches them watered with the vinegar solution. I put out bowls of the cider vinegar with the dawn to catch the adult gnats. I even sprayed with some plant
insect spray, but I really think it was way too old, so may need to get more. Anyway, still have gnats galore!!! ANY SUGGESTIONS? They are taking over. As soon as it gets warm enough I am moving these outside, but until then, the house is getting pretty crowded! About a gazillion gnats and 2 of us.
