Mice are much smaller than rats, but they can still do a lot of damage. They destroy food, books, furniture and even appliances with their gnawing, urine and droppings. Worse, mice in the home have been linked to a number of human diseases, including asthma. Because of their small size, they can fit through crevices as small as 1/4 inch wide, making them hard to control.
Don't let mice get in! Seal all openings - like cracks and spaces around vents, wires and pipes - with sheet metal, concrete or a product like "Stuf-fit" which is a knitted copper wire mesh. Screen necessary openings, like fans and chimneys with ¼ inch wire mesh. Doors and windows should be screened with tight fitting metal screens. Seal or cover all openings, since mice can jump 12 inches high, run up the sides of buildings and cross cables and wires.
