The bill amends Section 23-25-4 of the General Laws in Chapter 23-25, "Pesticide Control," by introducing new definitions and clarifying existing ones, particularly regarding anticoagulant rodenticides. It adds a definition for "First generation anticoagulant rodenticide," which includes active ingredients like Chlorophacinone, Diphacinone, and Warfarin, while updating terms such as "Active ingredient," "Beneficial insects," and "Integrated Pest Management (IPM)." The bill also deletes outdated language, replacing the previous definition of "Highly toxic pesticide" with a more comprehensive one based on the Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA). These changes aim to enhance clarity in pesticide regulation and improve environmental safety.

Additionally, the bill prohibits the sale of first-generation anticoagulant rodenticides in consumer and online retail stores starting March 1, 2026, and second-generation anticoagulant rodenticides starting January 1, 2027. It restricts their use, with exceptions for public health activities and agricultural sites, and establishes a "Rodent Integrated Pest Management Pilot Program Act" to promote science-based rodent management strategies. Municipalities can participate in this voluntary program, which includes inspections and tracking of pest management efficacy. The bill also creates an integrated pest management fund to support these efforts, with provisions set to expire on October 1, 2028, unless extended by the general assembly.
