Yikes!
Well the bad news is no matter what you do with THESE mice, there's a good likelihood that unless you get a professional to come and find where they are getting in, more will follow.
Mice can squeeze through an opening the size of a DIME, so that opening needs to be found and patched.
I think that you need to spend the money to have a professional fix this problem, because it may effect the health of your ratties.
