I think I found out what it is! I took Not A Member's advice and examined the plants and soil closely and saw what appeared to be some sort of silk around one of my younger VFTs. Upon probing the soil, I exposed a freaking larva of some sort! I found a couple more as well. One that I saw was about 1 mm long. I pulled another one out about 2-2.5 mm long. They are very skinny, perhaps as thin as a thick facial hair from a man. It looks like a worm or tiny caterpillar of some sort. They are white/translucent with a black head I believe. Any idea what these nasty buggers are? Should I spray with the aforementioned spray? The one I took out of the soil moved around a bit trying to get some place but died not too long after being pulled from the soil. I guess 2 days underwater wasn't enough.
Edit: I did some searching and they appear to be fungus gnat larva. Supposedly they are harmless though. Something is eating my plants though!
I know spider mites are usually associated with silk, but I don't believe that's what it is. I don't see any tiny insects on my plants at all. I only saw silky/fuzzy looking stuff in that one area of the pot.
