The purpose of the pantry is of course to store food. Last summer I went out and bought some plastic bins. Prior to the bin purchase, on a quiet evening you could hear rustling in the cupboard. I was always unsure of what the sound was but upon further inspection, I found nibble marks on the chip bag, gnawing marks on the potatoes and little round black things on the shelf. My diagnosis was MICE!! We have installed mouse traps and/or mice poison through out the place but just in case I now keep food in the mouse-proof bins.
