Bill
S 2721
Restricts routine anticoagulant rodenticide use to public-health emergencies; boosts oversight with IPM, reporting, and transparency to cut wildlife poisoning and contamination.
Status and timeline
- Introduced: September 4, 2025.
- Committee activity: Reported favorably by the Environment and Natural Resources Committee (filed 11/10/2025) and referred to Senate Ways and Means; listed as “REPORTED AND COMMITTED TO FINANCE.”
- Effective date: January 1, 2028.
Purpose
- To restrict routine environmental use of anticoagulant rodenticides and permit their limited use only under narrowly defined public‑health emergency circumstances, while increasing regulatory oversight, transparency and reporting.
Key definitions and scope
- Adds a definition to chapter 132B for “Anticoagulant rodenticide”: any pesticide whose mode of action interferes with blood clotting, including products containing any of these active ingredients: brodifacoum, bromadiolone, chlorophacinone, difenacoum, difethialone, diphacinone, or warfarin.
Primary provisions
1. Emergency-use regulatory framework (amendment to section 5, chapter 132B)
- Directs the state department (the agency charged under chapter 132B) with board approval to adopt regulations allowing limited use of anticoagulant rodenticides by licensed applicators only for public health emergencies. Examples include protection of drinking-water supplies, control of vectors for mosquito‑borne illness, and emergent infectious disease control.
- Permits a one‑time indoor use in a single location if the commissioner of public health determines a public health emergency exists. Such use must:
- Be limited to 14 days;
- Be accompanied by integrated pest management (IPM) including non‑chemical methods and exclusion measures;
- Include additional labeling (e.g., name of rodenticide on bait boxes);
- Be justified in writing explaining why anticoagulant rodenticide is necessary over non‑toxic short‑term alternatives;
- Require the applicator to report to the department after the 14‑day period and submit a plan for ongoing rodent control at the site.
Registration limitation (amendment to section 7, chapter 132B)
Transparency and reporting
Who is affected
- Licensed pesticide applicators and pest‑control firms (new restrictions, reporting and justification requirements).
- Manufacturers/registrants of anticoagulant rodenticides (limits on registration and reregistration).
- Public health authorities and the department administering chapter 132B (responsible for rulemaking, approvals and oversight).
- Property owners, water suppliers, and the public — through changes in availability/use of anticoagulant rodenticides and improved public reporting.
- Environment and wildlife — potential reduction in environmental contamination and secondary poisoning risks from anticoagulant compounds.
Potential impacts
- Reduces routine environmental use of anticoagulant rodenticides and reserves them for narrowly defined emergencies, likely lowering risks of non‑target wildlife and domestic animal poisoning and environmental contamination.
- Increases regulatory and administrative requirements for applicators (IPM, written justification, post‑use reporting) and for the department (rulemaking and annual public reporting).
- Could affect pest‑control practices and product availability; may encourage greater reliance on IPM and non‑chemical alternatives.
