Controls most rodent pests, including Rattus norvegicus, R. rattus, Mus musculus and M. domes
ticus, at lower rates than many other anticoagulants (e.g. warfarin and pindone); also Cricetus cri
cetus, esocricetus auratus, Microtus pennsylvanicus, M. pinetorum, R. argentiventer, R. rattus m
indanensis and rodents, such as hamsters, that are difficult to control with other anticoagulants. P
otency is such that a rodent may absorb a lethal dose by taking a 50 mg/kg bait as part of its food
intake on only one occasion. For a review, see A. P. Buckle & R. H. Smith, "Rodent Pests and the
ir Control", CABI (1994).
