Difethialone is an anticoagulant used as a rodenticide.^[1] It is considered a second generation agent.^[2]

In May 2008, the United States Environmental Protection Agency banned the use of difethialone in consumer-use rodenticide products and also for exterior use by commercial applicators.^[3][4]
