Number 1 carrier of rabies.
They gotta go.
Is there a woodlot? Pour food along their trail and put an end to coming all the way to the porch. Feed them there for a few days.
Once they're trained dig a post hole about a foot wide and 6 ft deep right next to the food bowl. Head shot from the correct angle might roll 'em right down the hole but if not ease 'em over the edge with a stick and shovel in the dirt.
If no wood lot is available the neighbor's back yard will just have to do.
