One of the most common active ingredients in rodenticides is known as brodifacoum. While it is used commonly in poisons to treat rats and mice, it also has been used to eliminate stray possums which trespass in places they aren’t wanted and even birds of prey like buzzards and vultures. This anticoagulant poison is highly lethal and can get the job done against a stubborn rodent infestation.

Solutions Pest & Lawn is happy to carry in our range of professional grade rodenticides products which contain brodifacoum. On this page, you can learn more about this brodifacoum, its mode of action and origins as well as browse and shop the brodifacoum-based products we have in our inventory.

What is Brodifacoum?

Brodifacoum is a highly lethal anticoagulant poison used in a number of rodenticide products in the pest control industry. In its original form it is a whitish odorless powder. An anticoagulant is a poison takes away the blood’s ability to clot. Brodifacoum is most widely used as a rodenticide to control mice, rats and other rodents that are difficult to kill with other anticoagulant rodent baits. On occasion it is also used to kill larger mammals such as possums.

Brodifacoum was first registered first introduced in 1975 to deal with the public health problem of rats and mice which were resistant to warfarin. Since then it has become highly popular and is featured in a variety of different rodenticides on the market.

How Brodifacoum Works

Brodifacoum’s mode of action is through inhibiting the vitamin K epoxide reductase in the vitamin K1-epoxide cycle, impeding the cyclic regeneration of vitamin K1, resulting in hypoprothrombinemia. In other words, it is an anticoagulant which works via preventing the clotting of blood by decreasing Vitamin K levels in the blood. 

Anticoagulents were originally discovered as naturally occurring in moldy sweet clover hay in the 1940s. Related compounds were later synthesized by manufacturing companies to produce a range of second generation anticoagulants that are more potent. Once ingested, Brodifacoum 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).

Rodents who ingest the poison do not show any symptoms of poisoning and continue to eat and function normally as it is a slow acting poison. The end result of brodifacoum is death from internal bleeding. Death is delayed; occurring within 3 to 10 days after feeding begins.

Why Buy These Products

Where is Brodifacoum used?

Brodifacoum 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.


Is Brodifacoum Safe To Use?

Brodifacoum is very highly toxic mammals and birds, and extremely lethal to fish. When it comes to humans it is less toxic because of its low bait concentration and slow-acting effect.  Brodifacoum should not be threat to humans, pets, or wildlife as long as it is used wisely and applied by following the label directions.


Products containing brodifacoum should always be placed in a tamper-proof bait station when used indoors where children and pets live.  


Brodifacoum has a half life of 157 days, causing it to remain active for several months. Gloves should be worn when handling bait blocks and make sure to wash hands after handling the bait, and avoid all contact with the mouth. Do not allow the bait to contaminate food or water supplies. If you, a pet or a child happen to accident ingest brodifacoum based products, call poison control immediately and consult a doctor. There is an antidote which can mitigate the effects of the poison known as Vitamin K1.
