If a squatter sets up camp on your front porch, that is technically “outside” your house. I suspect you would feel justified in removing them nonetheless.

That's a good job for sprinklers. The newspaper delivery person for the next door neighbor was wearing a path across the grass in my side yard. I posted a "No Trespassing - Keep off the grass" sign to no avail. The solution was to have my sprinkler system running from 6 AM to 7 AM on that part of the yard. The dumb bunny preferred to deliver the right way by walking up the neighbor's driveway and front walkway vs getting wetted by the sprinkler system.
