Miss. Code Ann. § 19-3-83

The board of supervisors of any county shall have the power to adopt reasonable ordinances for the regulation of transient vendors not inconsistent with the provisions of Sections 75-85-1 through 75-85-19 . However, such board of supervisors shall not have the power to declare residential solicitations by transient vendors who are citizens of the State of Mississippi, or who are agents of corporations domiciled in the State of Mississippi, or who are agents of foreign corporations qualified to do business in the State of Mississippi, to be a public nuisance or a misdemeanor, unless such transient vendors are not in compliance with Sections 75-85-1 through 75-85-19 or local regulations. Before transacting any business all transient vendors shall furnish to the county wherein such business is to be transacted, a good and sufficient penal bond in an amount not to exceed Two Thousand Dollars ($2,000.00) conditioned that if such transient vendor shall comply with all of the provisions of the county ordinances relating to transient vendors such obligation shall be void, otherwise, to remain in full force and effect. Any ordinance adopted by the board of supervisors of any county under the provisions of this section shall be applicable throughout the entire county, including any areas within any municipalities in such county, unless there is in effect or is subsequently adopted by the municipality its own ordinance under the provisions of Section 29-19-35, in which case the municipal ordinance shall control as to the area within such municipality.
