City-specific rules exist: Green Bay, Ashwaubenon, and De Pere have their own rodent control rules that differ from Brown County's county-level regulations. If you live in one of those cities, check the city-specific page instead.

Full Breakdown

Brown County Code § 38.01(3) names accumulations of decayed animal or vegetable matter, trash, rubbish, rotting lumber, bedding, packing material or scrap metal in which flies, mosquitoes, disease-carrying insects, rats or other vermin can breed as a declared public health nuisance. Section 38.01(2) separately bars anyone in the county from erecting, causing or maintaining any public nuisance, and the Brown County Public Health Department's Health Officer enforces both provisions against the property where the material accumulates.

Violations & Fines

Anyone who causes, creates or maintains the nuisance is guilty under § 38.01(2) and subject to the § 38.03 penalty: a forfeiture of not less than $5 nor more than $500 plus prosecution costs, with up to 90 days in county jail if the forfeiture and costs go unpaid.
