Rats and mice can be a major economic threat around swine facilities. They consume and contaminate feed and cause feed losses through the gnawing of holes in feed sacks and wooden bins. They also have been implicated in maintaining or spreading diseases.

The house mouse (Mus musculus), Norway rat (Rattus norvegicus), and roof rat (Rattus rattus) are common pests in and around livestock and farm facilities. Overall, the house mouse is the primary rodent pest for most confined farrow-to-finish operations. Norway rats and roof rats may affect both confinement operations as well outdoor operations such as hoop facilities, and pasture lot operations. Roof rats occupy the coastal areas of Washington, Oregon, and California, as well as a larger area along the Gulf and Atlantic Coast states from Texas east to Maryland. Roof rats are not established in the mid-western states.
