first thing is harden and seal your home so more mice cant get in.
even a tiny opening is a highway for them. once more cant get in a
humane livetrap with release outdoors will end the reentries.

its just like the mexico us border, make it as hard as possible to
leak in and DONT provide a ready food source. when you catch more than
2 mice in your home they were likely born there. with food they
multiply fast....
