The Wisconsin Department of Natural Resources has adopted the position that feral pigs are exotic, non-native wild animals that pose significant threats to both the environment and to agricultural operations. The department promotes aggressive removal anywhere feral pigs are reported.
- Feral pigs are considered unprotected wild animals with no closed season or harvest limit.
- Feral pigs are prohibited invasive species under Wisconsin's Invasive Species Rule, ch. NR 40 and are classified as a Harmful Wild Animal under the Captive Wildlife Rules, ch. NR 16.
- Feral pigs may be removed any time throughout the year as long as you possess a valid small game license and the permission of the landowner where you hunt.
- Landowners may shoot feral pigs on their own property without a hunting license, under DNR's animal nuisance control authority.
