Not sure if you're still here, hopefully you are... But I found this disgusting cluster of eggs/larvae/whatever the hell it is, that looks exactly like what you have here. BEHIND MY COUCH. I'm actually here on this forum because I, too, have been suspecting that I've been infected with some sort of parasite. So, I'm kind of dumbfounded right now!? I can post a pic if you want so you can tell me if it looks like what you've found here.
