I've told my landlord as soon as I noticed. Apparently the other tenants (who have been here longer) were aware but didn't care and weren't aware of the dangers of mice....

I wish I could do a no-kill solution, but I don't have a car, so taking the mice the 10 or so miles away isn't an option. I'm trying to use the most humane killing options available. The snap traps have stopped working, I might end up getting a zap trap. I won't use glue traps though - they're inhumane and don't even rhyme.
