Substitute House Bill No. 6915 seeks to ban the use of second-generation anticoagulant rodenticides in Connecticut, effective October 1, 2025. The bill specifically targets products containing active ingredients such as brodifacoum, bromadiolone, difenacoum, and difethialone. However, it allows for several exceptions, permitting their use by state employees for public health activities, water supply protection, mosquito control, and the eradication of nonnative invasive species on offshore islands, as well as in certain agricultural settings. The Commissioner of Energy and Environmental Protection is granted the authority to adopt regulations to ensure that the use of these rodenticides does not harm nontarget wildlife.

Additionally, the bill mandates that the Commissioner of Energy and Environmental Protection submit a report by January 1, 2027, analyzing the implications of current restrictions and licensing requirements related to these rodenticides. Violations of the ban could result in civil penalties of up to $5,000 per infraction. The bill also introduces a definition of "public health need," which refers to urgent situations posing significant health risks that require documentation to demonstrate the inadequacy of alternative rodent control methods. Overall, the implementation of this bill is projected to incur annual costs of approximately $101,462, including the need for additional staffing for enforcement, while also presenting potential revenue through fines based on the number of violations.
