Summary

Rock County treats any accumulation that lets flies, rats or other vermin breed, live, nest or shelter as a public health nuisance. The Health Officer can order property owners to clear rotting matter, trash and similar debris, with citations and forfeitures for anyone who ignores the order.

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

(F) Food or Breeding Places for Vermin, Insects, etc. - Accumulations of decayed animal or vegetable matter, trash, rubbish, garbage, rotting lumber bedding, packing material, scrap metal, animal and human fecal matter, or any substance in which flies, mosquitoes, disease-carrying insects, rats or other vermin can breed, live, nest or seek shelter.

Full Breakdown

112(2), it is the property owner's responsibility to keep the property nuisance-free and to abate or correct any such condition once it is found to exist. 112(4) directs the Health Officer or a designated representative to investigate every reported nuisance and determine whether it meets that definition. 112(5)(A) requires a written cleanup order specifying the corrective steps and a deadline of 24 hours up to 30 or more days, along with the penalty for non-compliance. 111(3)(A) and Wis. 112(5)(D) can bypass the written-order step and move straight to a citation or legal action.

112(6)(A) requires the Health Officer to first refer it to the appropriate state agency before acting locally, unless the state agency does not adequately address it.

Violations & Fines

Forfeitures follow the schedule adopted by County Resolution 08-8A-054, with jail of up to 60 days in Rock County Jail if a forfeiture judgment goes unpaid, per Section 6.111(5)(A). A separate offense is charged for each 10-day period the vermin-breeding condition continues uncorrected, shortened to 24 hours if the Health Officer determines it is an immediate health hazard.

Frequently Asked Questions

What counts as a rodent or vermin nuisance in Rock County?
Section 6.112(3)(F) covers accumulations of decayed matter, trash, rubbish, garbage, rotting lumber, packing material, scrap metal, or fecal matter where flies, mosquitoes, rats or other vermin can breed, live, nest or find shelter on a property.
Does the county inspect before issuing an order?
Yes. Section 6.112(4) requires the Health Officer or a designated representative to investigate every reported condition and determine whether it actually meets the public nuisance definition before any abatement order is written.
What happens if I don't clean up after being ordered to?
You can be cited under Section 6.111(3)(A) and Wis. Stat. § 66.0113, face forfeiture proceedings brought by the District Attorney, or have the County abate the condition and bill you or assess the cost against the property.
Can the county act immediately without a written warning?
In extreme cases or where the same person repeats the same violation, Section 6.112(5)(D) allows the Health Officer to issue a citation or begin legal action immediately, skipping the standard written-order step.
