You pretty much have to, unless you enjoy their company.
Only the fancy ones (unless feeding it to a snake, that would be fine). HOWEVER, killing a house mice is not illegal, and therefore should be killed.
it is possible so maybe
Candy tells George that he should have killed his dog on page 44 of Of Mice and Men.

You really don't have to train your ferrets to hunt house mice, it should be a natural instinct for them to kill the mice. Also, just the smell of ferrets should keep mice away.
Yes, mice have a tendency to return to the same house if they have found a reliable source of food and shelter there.
House Mice
There are several types of mice and rats that can be found in different environments, including house mice, deer mice, field mice, and Norway rats. These rodents can adapt to various habitats such as homes, fields, forests, and urban areas.
Mouse traps from local Farm Supplies help. Or, a house cat. When you get a mouse trap, put peanut butter or cheese on it :).
no sick mice should be caged with healthy mice, unless you have the mice checked by a certified vet. Also if the sickness contagious to other animals you should go to the vet and take the sickness taken care of. So if you have a sick mouse DON'T house it with other mice.
it might be other mice. I have seen this happen before and its not uncommon.
