AN ACT Relating to rodenticides;
HB 2516 would place a temporary moratorium on the use of certain rodenticides in Washington, specifically anticoagulant rodenticides and rodenticides containing bromethalin as an active ingredient. The bill states legislative findings that these products may harm human and wildlife health and that safer, effective alternatives exist. It also emphasizes Washington’s commitment to integrated pest management and the need to reduce reliance on chemical rodent control.
The bill directs the Department of Agriculture to report to the Legislature by December 1, 2025, identifying all registered anticoagulant rodenticides and bromethalin-containing rodenticides. It then prohibits use of those products from January 1, 2026 through December 31, 2026, while allowing the director to establish a process and standards for limited emergency use by qualified third-party agents in situations involving drinking water protection, mosquito-borne disease control, or emergent infectious disease control. The moratorium section expires June 30, 2027.
HB 2516 also requires the Washington State Academy of Sciences to conduct a study on rodenticide use and safety. The study must examine Washington-specific issues relevant to possible use restrictions, gaps in existing research, the viability of contraceptives and other non-toxic rodent control methods, and recommendations for further research. The Academy must submit its findings to the Legislature by December 1, 2026, and that study section also expires June 30, 2027.
The bill’s impact would be to temporarily restrict a class of widely used pest-control chemicals, create a state reporting and research process, and potentially influence future regulation of rodenticides in Washington. It would affect pesticide users, pest control operators, agricultural and property management interests, and agencies responsible for pesticide registration and public health or environmental protection. By framing the issue as a health and wildlife protection measure, the bill could also shape future policy toward non-chemical rodent control and integrated pest management.
Because no committee transcripts or votes were provided, there is no recorded legislative debate or voting history to gauge sentiment or identify specific points of contention. Based on the bill text alone, the measure appears to be driven by environmental and public-health concerns, but it also includes a narrow emergency-use exception that suggests an attempt to balance restrictions with operational needs. Likely areas of contention would be the scope of the moratorium, the practicality of emergency exemptions, and whether the state should restrict these products before the study is completed.
HB 2516 would amend Washington’s pesticide/rodenticide regulatory framework by creating a one-year moratorium on anticoagulant rodenticides and bromethalin-containing rodenticides, with limited emergency-use authority and sunset dates. It also requires a state study and reporting obligations, which could inform future statutory or regulatory changes affecting pesticide registration, pest management practices, and public-health or environmental protections.
No committee discussion or vote history was provided, so there is no direct evidence of legislative sentiment. From the bill text, the measure is framed positively around human health, wildlife protection, and integrated pest management, indicating support from proponents of environmental and public-health regulation. At the same time, the inclusion of emergency-use exceptions suggests awareness of practical concerns that may have been raised by users of rodenticides or agencies responsible for disease and water protection.
The main likely points of contention are whether Washington should impose a moratorium before the study is completed, whether anticoagulant rodenticides and bromethalin should be treated as a broad category rather than product-by-product, and whether the emergency-use exception is sufficiently narrow or too restrictive. Potentially affected stakeholders include pest control operators, agricultural interests, property managers, public-health agencies, and environmental and wildlife advocates.
