Assessment Topic

This document presents the Agency's assessment of potential risks to birds and nontarget mammals from 9 rodenticides including 3 second-generation anticoagulants (brodifacoum, difethialone, bromadiolone), 3 first-generation anticoagulants (diphacinon, chlorophacinone, warfarin), and 3 non-anticoagulant compounds (zinc phosphide, bromethalin, chlorocalciferol). These rodenticides are predominantly used to control commensal rats and mice in and around buildings, transport vehicles, and in sewers. A major concern in using rodenticides is that they are not selective to the target species; birds and nontarget mammals that feed on grain-based baits (pellets, meal treated grains, wax blocks) or meat-based, vegetable, or fruit baits are potentially at risk.
