Selontra® Rodent Bait (BASF, Ludwigshafen, Germany) is a cholecalciferol-based soft bait that exhibits high palatability both in the lab and field. Because of the attributes and mode of action of cholecalciferol, isolated field populations of rodents can often be controlled by Selontra within one week after initial bait exposure. Baiting trials were established at five sites in the city of New Orleans, Louisiana to investigate the field efficacy of Selontra against roof rats (three sites) and Norway rats (two sites). Comparison of pre- and post-baiting census data indicates an average control rate of 97.7% for roof rats and 88.5% for Norway rats.
