Strange Odors

My plumbing seems fine, and yet I have strange odors coming from the drains in one bathroom.
Here's what I've done: snaked the tub drain, removed and cleaned sink p-trap, removed & cleaned the tub
drain closing mechanism, temporarily blocked sink drain pipe to soak sink overflow with bleach. I have also climbed up on the roof with the garden
hose & shot water down the vent stack. The drains & toilet all flow well, so I think a blocked vent is unlikely. The p-traps have water in them.
We use a septic tank. What should I try next? Would installing a trap on the bigger drain pipe under the house help?
