Larry gets in the trenches with the citizens who deal with critters that have invaded our country. First, Larry teams with a relentless pair of guys who use GPS-enhanced dogs and their own brawn to deal with the persistent, pesky and very scary problem that is the feral pig. Larry then heads to Louisiana to catch nutria, a large, ugly and very hungry rodent that has been destroying the natural vegetation and chowing down on the levies. Larry ends his trip at a “carp rodeo” in Iowa, a wild and watery way to control the population of a voracious species of fish.
