Mice! - In Bulgaria

In Bulgaria, how do you get rid of mice in the house?
A cat, traps, poison or other methods unknown. A cat is a no, no in the home and the BG traps are too big an not sensitive enough for the wee mice that infest the house. Poison had to be resorted to and the wonder of whether there is another method unknown to me at present that could be used. Every house I know has mice problems right now! Any ideas?
