You can ask the bum to leave.
If he leaves, your problem is solved, just don't allow him back into your home, or on your property.
You could even offer him $200 (or whatever it takes) to leave, and sign a document saying something along these lines:
"I, John Doe, voluntarily agree to permanently vacate the home of Bobby Green at 123 Happy Street, in the city of Laughing, state of Georgia for the sum of $200."
Signed this 1st day of March 2019
____________________ John Doe
____________________ Bobby Green
Once he has left, you should IMMEDIATELY change all locks and alarm codes.
==============================================================
If none of that occurs you must do the following:
You may legally remove a Tenant and the Tenant's property from rented premises only under the Dispossessory procedure.
If a Landlord uses self-help to evict a Tenant without benefit of a Dispossessory action, it is a tort for which the Tenant may recover damages in a civil action.
Any landlord who cuts off utilities may be subject to misdemeanor prosecution under OCGA 44-7-14.1.
