get a kitty. We have moved into homes with serious mouse problems and once we got a good mousing cat (try to get one that was trained by his/her mother) then the mice pretty quickly disapeared. The cat often makes a good pet for kids too. If the cat doesn't mouse, lessen the amount of catfood availabe, the cat will soon be happy to suppliment his meal. Just make sure to take care of the cat with shots and fixing. The whole cat cost is can range from $100-500 for medical expensies and the cats themselves are often free or cheap.
