Make it legal to shoot them on sight.
That sounds like a plan.
I hear in WI it is against the law to NOT shoot them. Or at least was.
BTW, some farmers use wildlife damage as reason to file for crop damage. Then they post their property. If they want to claim crop damage, they should be required to allow a certain number of boar hunters on their property for a certain amount of time.
Yet hard core liberal bureaucrats still refuse to relax the death grip hold via over regulation to hunt these animals. Bureaucrats don't want to risk losing their hold over peoples lives by greatly relaxing the rules and regulations to hunt these boars down and thin their ranks. Government as usual standing in your way.
Or, we could train the, "killer hornets" to take them out.
