I say take off and nuke the entire site from orbit. It's the only way to be sure.

May want to try a "drain king" as well. I've had some luck with one and it's not as destructive as a snake. Poor mans jet flush.

We have a fancy tub in the bathroom and never use it. Started to smell--turned out enough water evaporated from the trap that we were smelling the pipe on the other side. Run water through every now and then and it's fixed. Bonus - the cat thinks it's the most interesting thing she's ever seen when we run the water there so we do it every night now.
