Agrid3 is the first and only rodenticide registered by the Environmental Protection Agency, EPA, and listed by the Organic Materials Review Institute, OMRI, for use in organic production. Its organic production label includes food processing, warehousing/storage and animal production, as well as in and around agricultural buildings, such as swine, poultry, cattle and dairy facilities. Agrid3 combines the most recent advances in bait formulation with the benefits of cholecalciferol (vitamin D3). Agrid3 kills anticoagulant-resistant rats and mice yet reduces the risk of secondary poisoning. It also poses low toxicity to birds. Rodent's cease feeding after consuming a toxic dose.
