While warfarins can be lifesaving, superwarfarins are deadly – and not just to rodents

Last month, the police superintendent of New Orleans, Louisiana revealed an unusual problem to members of the New Orleans City Council’s Criminal Justice Committee. A pest infestation at police headquarters was contributing to ‘deplorable’ conditions, evidence control issues and beyond. ‘The rats eating our marijuana, they’re all high,’ the superintendent said. While this news elicited jokes and jibes, evidence destruction is no laughing matter. To protect these critical materials, evidence managers may turn to pest management professionals, who most often rely on anticoagulant rodenticides.
