Reply #1: Egads if they are rats!

Am assuming you are finding the evidence of mice in the kitchen area? Best way to get rid of them is first, do what you are doing - sealing off all openings. Caulk around pipes under the sink, pull out the appliances, seal everything that even looks like it might be an opening. Mice can get in through the smallest of openings. Clean up all crumbs, keep a cover on the kitchen waste can. The only thing I can recommend is poison specifically for mice - the kind I used was a pellet type - and put a baby gate up to keep the pup out of the kitchen. That's what I did with my dog. It will take several days. I haven't had any problems since - I think primarily because I sealed and caulked around pipes and any openings. Good luck!
