Frank,
I use Grant ant cups for the ants, takes a week or two for them to go away.
For mice you have to find where they are getting in and seal it up. I use the canned insulation foam. Go all around the foundation and seal up any holes you see, no matter how small. Seal around wires and pipes. I like snap traps and glue traps over d con and poison because I like to get rid of them when they die as opposed to having them die in the walls.
Took me over a year before I found where the mice were getting in, I finally made the connection when I looked for the pipes that went to a slop sink in my garage. They were under a set of stairs that were enclosed. I pulled the top off and found two 1 and 3/4 inch holes for 1/2 inch copper pipes. It was a mouse highway. Once I sealed those two holes (plus about 10 others) I haven't seen another mouse since.
Good luck.
