I definitely appreciate the input but I think I've pretty much got the bugs under control. Being that I'm down to almost zero gnats I'm guessing that the larvae have been mostly dead for a week or so now. What I'm asking is whether or not one would expect their plants to continue dying off this long? My plants are still continuing to turn yellow, dry up and die (although, at a much slower pace) and I'm starting to wonder if I have another problem in addition to the gnats.
