Poison is generally dangerous for other animals and there is nothing worse than for several to die in the wall of your home and rot.

Making sure there is nothing to eat is helpful to reduce numbers. Raptors, foxes, cats, etc. are all helpful, but the best bet is a rat snake or two. They will eat the young before they get big enough to escape and can go anyplace the mice/rats go. Otherwise, traps are necessary. Most kill instantly. All the above (except poison) is my vote.

If you actually see them moving around in the daylight, you have a very serious infestation. On the farm, we shot those. A good pellet gun or slingshot is quiet and will do the job if you have some skill and don't want to spend on ammunition.
