What do I do about what I suspect is a mouse in my pantry?

OK, I know about the mousetrap thing (but I really don’t want to deal with a broken-necked little rodent).

I found poop (let’s just call it evidence, shall we?). I found evidence that some small critter has found a home in my pantry. If I use the sweeper to pick up the mess (and the evidence), do I risk sucking up his little rodent body with the sweeper (it isn’t a Dyson)?

I did see a mouse in the basement the other day, but now they are eating MY food. My dog killed a rat on the back deck recently (so I do NOT want to tangle with whatever rodent is in the pantry). The “evidence” would imply that the little turkey is not real big but I am not an expert in rodent evidence.

I am looking for suggestions (I know, “put the carcass in the frizzer,” etc.) I just don’t want a first-hand encounter with the fuzzy little irritant.
