Certain Rat Poisons Banned


Goes into effect January 1, 2021.


SACRAMENTO, Calif. — California Gov. Gavin Newsom on Sept. 29 signed into law AB 1788, “The California Ecosystems Protection Act,” which prohibits most uses of second-generation anticoagulant rodenticides (SGARs). AB 1788 was passed by the California Legislature on Aug. 31.    

AB 1788 prohibits most uses of rodenticides containing brodifacoum, bromadiolone, difenacoum or difethialone to reduce the poisoning of non-target wildlife until the re-evaluation by the Department of Pesticide Regulation (DPR) is completed; the Department of Fish and Wildlife (DFW) also will play a consultation role in the re-evaluation.

The bill was in response to studies that showed the detectable levels of SGARs in wildlife had not declined despite a consumer ban of the products in 2014.
