One adult mouse can consume between three and four grams of food per day, and mice like many of the same foods we do: cereals, grains, seeds, nuts, fruits, meats, chocolate, and candy. Mice especially like foods that are high in fat, such as bacon, cheese, and butter. They'll make up to 30 visits a day to an identified food source, such as a pantry or cupboard. Strange holes or tears in packages are indications that mice may be raiding your pantry. If you think you've been sharing food with mice, throw it away—food that has been contaminated by mice may cause dangerous illnesses in humans, including salmonella, hantavirus, and fever.
