An Act authorizing the town of Ayer to prohibit the use or sale of second-generation anti-coagulant rodenticides

194th Legislature (2025-2026) Introduced by Dan Sena

The bill would authorize the Town of Ayer to prohibit the use and sale of second-generation anticoagulant rodenticides within its borders.

Referred to the committee on Environment and Natural Resources

Summary of Bill: H 5563 (194th MA Legislature)

Purpose and intent

This act authorizes the town of Ayer to prohibit the use or sale of second-generation anticoagulant rodenticides (SGARs) within its borders.

The measure is framed as granting local authority to regulate or limit SGARs to address environmental and public health concerns associated with these toxic substances.

Key provisions

Authorization for local action: The bill explicitly empowers the Town of Ayer to prohibit, through local ordinance or other lawful means, the use or sale of second-generation anticoagulant rodenticides within the town.

Scope of regulation: The prohibition would cover both the use (application) and sale (distribution/retail) of SGAR products. The bill relies on local governance to implement and enforce such restrictions.

Local governance standard: The bill does not create a statewide ban; rather, it provides Ayer with the statutory authority to regulate SGARs locally, subject to compliance with broader state and federal laws.

Enforcement and penalties: The text as summarized here does not specify penalty structures; typically, local regulations would include enforcement mechanisms and potential penalties consistent with town ordinances. Specifics would be determined by Ayer’s adopted ordinances if the bill is enacted.

Who would be affected

Primary: Residents and businesses in the Town of Ayer, including homeowners, pest control operators, retailers selling rodenticides, and any municipal agencies responsible for public health or environmental stewardship within Ayer.

Secondary: Suppliers and retailers outside Ayer who might be affected if cross-border sales occur, though the prohibition would apply to sales within Ayer’s jurisdiction. Statewide retailers with stores in Ayer would need to comply with any local restriction when operating in town limits.

Procedural and timeline aspects

Status: Referred to the Massachusetts House Committee on Environment and Natural Resources on July 6, 2026.

Sponsorship: Co-sponsor listed as Dan Sena.

Next steps: If forwarded by the committee and ultimately enacted, the town of Ayer would need to adopt appropriate local ordinances and implement enforcement mechanisms, subject to the bill’s authorization.

Potential impact and considerations

Environmental and public health impact: SGARs have been linked to secondary poisoning of non-target wildlife and potential human health concerns; allowing local prohibition could reduce exposure and ecological risk within Ayer.

Local autonomy: The bill emphasizes local control, enabling Ayer to tailor rodenticide regulation to its specific environmental and community needs.

Implementation considerations: Effective enforcement would require clear local rules, appropriate education for residents and retailers, and coordination with state and federal pesticide regulations.
