My first course of action would be to call an exterminator, not try to fix this myself. They know all the "rat tricks" about how they come and go and can do a much better job than you guessing that you know all the entry points and such. Whatever they charge you, it's well worth it to get it behind you.

And write a song about it. Maybe call it "Come And Rat Me Out".
