What does brodifacoum do to rats?

Brodifacoum is a potent anticoagulant rodenticide that disrupts the normal clotting process in rats by inhibiting vitamin K epoxide reductase, which is essential for the synthesis of clotting factors. As a result, affected rats experience internal bleeding, leading to severe hemorrhaging and eventual death. The compound is highly toxic and can cause death even at low doses, making it effective for rodent control. However, its use raises concerns about secondary poisoning in non-target animals and environmental impacts.
