Best ways of getting rid of mice without traps or poison

Cats can get hurt by black-widow spiders too, do note.

Having had Evil Mice cause considerable damage in a car, I am of the mind of Nuke them From Orbit.
Also, just because they are cute and widdle, doesn’t mean they aren’t freakin’ savages.
I work in a bakery and we have humane mouse traps. Whenever mice are found in there, there will be one half eaten dead mouse. One mouse that has bites out of him and looking to be on the verge of a nervous breakdown and one FAT mouse. And blood everywhere in the trap
They are freakin’ evil.

(Lobsters, in the lobster tank in stores, apparently, are just as nasty. Which is why they have rubber bands over their claws. )
