Blocking up openings to my room isn't really feasible--new doors to the room would be required. As far as blocking entrances to the house, that's the landlord's responsibility, and one I *hope* he'll be taking seriously. Likewise, any hiring kind of professional is also something the landlord would have to do, not us tenants. But trapping is something I can do, assuming I can find a trap that traps!

It's interesting that mice went into the humane traps in one state and not in another. I wonder if New York mice are better at transmitting the wisdom of their elders.
