The gray thing sounds quite disgusting! Congratulations! You beat me on that one! :)
As I said in the other forum, bleach won't kill the little BUGgers but a streamer might. I was steaming regularly and it seemed to help a lot but I just don't have the energy to bother right now.
I know what you mean about people! I live across the country from most of my family, so I sent an email to let them know just a tiny bit about what I had found out about my little problems and wanted them to be aware that I was not doing too well. The response was truly interesting! Some of them stopped emailing me all together! I haven't heard from them since and one has recently come around to talking to me a bit because she passed a living parasite that was 2 1/2 inches long, with a big knobby head.
