Depending on the type of mice or geographical location perhaps. There can be bad things in their feces. Tracked when dry may make it airborne.


I am no expert on this and do not know where this is a serious factor. Nature also has some effect on population levels. Adaquate food easily available might encourage larger reproduction numbers.


Again remember I really know sh-t about these things but just things from random memory. They are cute little creatures but not desirable as house guests.


Personally I dislike killing things but sometimes it has to be as well.
