BLOOMINGTON, Ind. (AP) — Efforts are underway by federal and state workers in Indiana to eradicate feral pigs from the state.

Feral pigs are considered an invasive species that can root out huge portions of agriculture lands, crops and fields.

The Herald Times reports that plans to rid Indiana of an estimated 500 wild pigs don’t include hunting. Officials say they’re using baiting traps to take out groups of pigs at once. Indiana Department of Natural Resources wildlife research biologist Steve Backs says wild pigs have been in Indiana for the past 25 years.

They can be genetic combination of Eurasian wild pigs, domestic pigs and pot-bellied pigs.

The state received federal funding through the 2014 Farm Bill that allotted $20 million for a five-year effort to help combat the increasing population of wild pigs across the country.
