Florissant, MO Public Health Rules: Rodent Control (2026)

010 of the Florissant Code of Ordinances, in Chapter 213's Article on nuisances generally, lists fifteen specific conditions declared to be nuisances affecting health. Two reach rodent control directly: Subsection A(6) declares garbage cans that are not fly-tight, meaning cans that do not prevent the entry of flies, insects and rodents, to be a health nuisance, and Subsection A(12) separately declares any and all infestations of flies, fleas, roaches, lice, ticks, rats, mice, fly maggots, mosquito larvae and hookworm larvae to be a nuisance in their own right.

Subsection B makes it unlawful for any owner, lessee or occupant, or their agent, to cause, permit or maintain a nuisance on any occupied lot within the City or within one-half mile of the City limits, and treats each day the nuisance continues as a separate offense. 040: the Building Commissioner can declare that a nuisance exists, give written notice by personal service, certified mail or posting, and order the condition removed or abated within seven days, while giving the property owner a right to request a hearing on whether a nuisance actually exists.

050, which becomes a special tax bill, or is added to the property's annual real estate tax bill, and stands as a lien on the property until paid. 010(C) lets the City abate the nuisance immediately without waiting for the notice process.
