Individual bait blocks in a 9lb bucket. Peanut flavored.The active ingredient in this rat killing bait (Bromadiolone) is a single feed anticoagulant that is less toxic to non-target animals than conventional anticoagulant rat and mouse baits. Primary and secondary kill is a major concern if you have pets or wildlife that might accidentally come into contact with your rat bait or might capture a rodent that has consumed a lethal dose of rat bait. Rodenticides should always be located in areas where rodents will easily find the bait but out of reach of children, pets, wildlife and non-target animals.
