Mice migrate to structures as they search for food and shelter. They will eat a wide range of food, but prefer foods high in fat and sugar. Some favorites include chocolate, bacon, butter and nuts. Most water requirements are filled by the food they eat.
Mice and rats are active at night, mice can roam undetected throughout a household. If you see them during the daytime, this could indicate you have several mice in the house. Rats have a high reproductive rate. Within a matter of months, a pair of mice can produce several litters. With abundant food, each litter can have 10-12 young. These litters can then begin producing mice within two months of birth.
