My question is how to get rid of them effectively. At this point there
is no mouse accessible food left in the basement.

A few years ago I would have said "Get a cat".
Then, I discovered my best hunting cat was depositing live mice in my
basement.
Apparently he wanted to have something to hunt when the weather turned cold
outside and decided to set up his own game preserve.

The spring traps work best, but vary your bait - use peanut butter on one,
cheese on one, fruit on another.
