Just reading this thread. I was going to suggest looking for a Bobbit. I had one, about a foot long (baby?). Keep an eye out for another; if he came in on the rock, there's no telling how many you might have. When I killed mine (pulled rock, boiling water & bleach sauna) I spent about 2 months making sure there were no more.
