Description Pyriminil was used formerly as a rodenticide in products such as DLP 787 as a 10% house mouse tracking powder or Vacor. It is now banned in the United States and Europe for use as a rodenticide and is listed as an extremely hazardous substance by the US Environmental Protection Agency (EPA). Toxic effects of pyriminil include neurotoxicity and pancreatic beta-cell death, which, if not immediately lethal, will lead to prolonged autonomic dysfunction and permanent insulin-dependent diabetes mellitus in most species, including humans.
Uses Rodenticide. Pyriminil was used as a rodenticide in the United States to control rats and house mice since the 1920s. It is especially effective against rodents resistant to anticoagulant poisons. Pyriminil was marketed for indoor use only in the form of bait and tracking powder. However, commercial distribution was voluntarily withdrawn in 1975 in the United States after many severe human poisonings and suicides. In contrast, pyriminil was introduced to British market much later (in 1980).
