Twin Falls County, ID Public Health Rules: Rodent Control (2026)

Twin Falls County's zoning nuisance section, 8-9-16, names trash accumulation that lets rodents live, or insects such as flies and mosquitoes breed, as one of the specific examples of a nuisance condition subject to county abatement in the unincorporated area outside the cities' areas of impact. The county does not run a separate stand-alone rodent or vector control chapter; instead, this trash-and-harborage clause inside the general nuisance section is the tool the county uses against a property whose accumulated trash, junk or debris draws rodents.

Enforcement follows the same path as any other nuisance under the section: the County Prosecutor, or a deputy prosecutor, may file a civil or criminal action to enjoin or abate the rodent-harboring condition, and before that the property owner or the person responsible for the trash is entitled to a written notice, served personally or by certified mail, or posted on the property if the owner cannot be located, describing the condition and giving fifteen days to clean it up. If the accumulation is bad enough to be an immediate and emergent threat to public health, the county can abate it summarily without waiting on the notice period, then bill the property owner for the cost.

An owner who ignores the notice can be sued civilly or prosecuted criminally, and the county's costs to clear the trash, including any outside contractor hired to do the work, attach as a lien on the property if the owner does not pay. Each day the rodent-harboring trash accumulation is allowed to remain is treated as a separate violation under the section.
