Mice have become a nuisance and unsolvable problem in our houses, offices and shops. Have you ever imagined when, where and how these troublesome mice sleep? Mice sleep mostly during day-time for 14 hours in holes made by them in our houses and surroundings; and inside boxes/things etc. kept by us under the cots, over the lofts, in the kitchen shelves and wherever things are dumped by us providing hiding places for the mice, and they sleep mostly in sitting posture.
