Nor is she enamored with the idea of switching to bromethalin. "There is no antidote," she says, noting that this makes the compound a potential risk to children and pets. AR poisoning, by contrast, can be treated using vitamin K.
Better policy, says Fairbrother, might be to ban permanent bait stations and to require pest-control operators to use ARs only as needed. Consumers should also be told about the potential ecological effects of such compounds.
"We know consumers can comprehend and respond to warnings about wildlife exposures," says Fairbrother.
