The Tomcat BL22244 Rat and Mouse Poison (4lb Pail) delivers fast, effective control of Norway rats, roof rats, and house mice—even those resistant to anticoagulants. Formulated with Bromethalin, this acute-acting bait causes rodents to stop feeding after consuming a lethal dose, reducing bait waste and speeding up results. Each 1 oz. bait block kills up to 12 mice, while 4 oz. blocks can eliminate up to 10 rats. Ideal for agricultural and professional use, this bait must be used within 100 feet of man-made structures and placed in tamper-resistant bait stations when accessible to children or pets.
