What is Bromadiolone Rodenticide?
Bromadiolone is a commonly used rodenticide. It is the key ingredient in the products Contrac Blox and Contrac Pellets manufactured by Bell Labs. Bromadiolone has been called a "super-Wayfarin" because it can eliminate Wayfarin resistant rodents. Bromadiolone is typically used to control rats and mice. Always use Bromadiolone as directed, typically with an EPA approved tamper resistant bait station, because it is highly toxic to humans, pets, and wildlife.
Where is Bromadiolone Rodenticide used?
Bromadiolone is used to control persistent rodent populations such as Norway rats, roof rats, mice, field rodents, opossums, and raccoons. It can be applied inside and outside of industrial buildings and homes, in alleys, port terminals, sewers, farmhouses, grain stores, factories, fields, and transport vehicles such as trains, ships, and aircraft. In most areas, a tamper resistant bait station is required by law to avoid accidental poisoning of humans and unintended species.
How does Bromadiolone work?
Bromadiolone is a second generation anticoagulant that works by preventing the clotting of blood by decreasing Vitamin K levels in the blood. The first anticoagulants were discovered as naturally occurring in moldy sweet clover hay in the 1940s. Related compounds were later synthesized by pharmaceutical companies to produce a range of second generation anticoagulants that are more potent. After ingestion, Bromadiolone absorbs into the liver and interferes with the synthesis of vitamin K-dependent clotting factors. Eventually the blood ceases to clot and permeates the artery walls. The rodent dies of multiple causes related to blood loss. Vitamin K1 works as an antidote for accidental ingestion, and prolonged treatment is required because it has a long half life (up to several months). Bromadiolone eliminates rats in a matter of days.
