Bromadiolone is a type of second-generation anticoagulant rodenticide poison. It works by causing internal bleeding in the rodent, leading to death. Bromadiolone is used to control rats and mice in both agricultural and non-agricultural settings. It is typically applied as a bait in the form of a grain or pellet. It is usually found in block or pellet form, but can also be found in liquid or paste form. Bromadiolone is a commonly used rodenticide and is registered for use in most countries. It is considered a low hazard to non-target species if used correctly.
