prohibiting the use of certain second generation anticoagulant rodenticides.

HB 1018 prohibits the use of four specific rat poisons (brodifacoum, bromadiolone, difenacoum, and difethialone) in New Hampshire, primarily affecting pest control businesses, property owners, and general commercial users. The ban takes effect January 1, 2027, with key exceptions allowing these products for public health activities (like protecting drinking water or controlling documented infestations), medical waste facilities, and certain agricultural settings including food storage warehouses, slaughterhouses, and breweries. The law does not ban all rodenticides, only these four second-generation anticoagulant types. It directly changes pesticide regulations under RSA 430:41.
