You could put out traps, yet this is not a very humane way to rid your apartment of the mice. The obvious answer to to get a cat, as you know from Tom and Jerry, these two don't normally live in peace together, although on T. V. the mouse wins, in real life the cat normally does.
Thre are companies who specialise in exterminating household pests, and if you don't want to lie in bed at night, listening for the snap of the trap on the mouse, or it scampering around looking for water, only to die an extremely
painful death after eating rat poison, I suggest you call them.
