Feeding on grains, oats, and corn, house mice breed year round, having as many as 10 litters a year. Born less than 20 days after mating, young mice are ready for reproduction within two months — paving the way for exponential growth.
Due to their ravenous appetites, even small populations of mice can inflict lasting damage and contaminate uneaten food with droppings, urine, and saliva. Agile climbers and jumpers, mice can enter your home through very tiny cracks and holes barely visible to the human eye.
With lifespans of less than a year, mice can live outdoors, but they prefer living in structures, often alongside humans.
