House rejects bill directing state action on invasive Norway/roof rats

The Idaho House on March 17 rejected Senate Bill 12‑71, a proposal that would have directed the Idaho Department of Agriculture to collect data, coordinate with private and local entities, educate the public and publish an abatement plan addressing invasive Norway and roof rats.

Sponsor Representative (speaker 9) framed the measure as a limited, proactive step to assess the scope of infestations and develop a plan so the state would not be “caught flat‑footed,” saying counties such as Ada and Canyon already report presence and that the species can spread rapidly through waterways. "One rat can have over 800 offspring in two years," the sponsor said during floor remarks.

Opponents argued the issue is primarily local and warned that bringing a state agency in would expand government responsibility and potentially create future budgetary obligations. "This is a local issue," one lawmaker said, urging local abatement districts and private agreements rather than a statewide program.

Several lawmakers stressed uncertainty about costs and resources for implementing contracts that the Department of Agriculture might use. A critic noted the bill’s fiscal note said there would be no immediate impact, but said state involvement typically leads to later funding requests.

The House voted 32 ayes and 38 nays; the House clerk announced the bill failed and it will be returned to the Senate. The debate combined concerns over public‑safety and agricultural damage with disagreements about whether prevention should be local or state‑led.

Next steps: because the bill failed on final passage, the measure will return to the Senate. Legislators and stakeholders may continue discussions in committee or pursue local responses independently.
