Have you considered getting a cat? You could get a young female (best mousers) from the local animal shelter, get her spayed so you don't end up with a cat problem, and keep her outside with access to the basement. Get a couple and keep them out side and the mice won't make it across the lawn to the basement in the first place.
Are you for real ....come on I am serious here!!!!!! If you want to joke start your own thread about your house.
