Mice are a common household pest in Utah. The house mouse does not hibernate, and as temperatures drop in the fall and early winter, they migrate into homes seeking food, warmth, and shelter. People do an excellent job providing these basic needs to mice. Mice investigate house perimeters for warm air and food odors leaking out from any opening. Mice only need a hole about the size of a #2 pencil (1/2” high by 3/8” wide) to gain access to your home. They are unwanted visitors capable of spoiling food with fur, urine and feces, and transmitting disease. A few important steps can minimize mice in the home.
