As I was pruning and spraying my VFTs, some little white worms started wriggling their way out of the peat. They are very small, clear and a bit brown on the bottom. They seemed to respond negatively to the neem oil I was spraying. I saw only four and managed to pull them out iwth tweezers. Can anyone tell me what the heck these things are, how much of a threat they pose to my CPs, and how do I get rid of them?
