Chlorophacinone

Chlorophacinone belongs to the indandione chemical class and acts as a potent indirect-acting blood anticoagulant. It possesses cumulative properties, gradually building up in the pest's organism over repeated exposure.

The mode of action involves blocking the synthesis of vitamin K1 in the rodent's liver. This causes a critical reduction in blood prothrombin levels, effectively making the blood clotting process impossible.

As a result, the animal suffers from extensive internal bleeding. Death typically occurs within 3 to 7 days after ingestion, which significantly reduces the suspicion of the rest of the colony.

A key advantage of this substance is the lack of "bait shyness" in rodents. Because the effect is delayed, the pests do not associate the consumption of the bait with the death of their counterparts.

Chlorophacinone demonstrates high efficacy even at low concentrations in food baits, allowing for minimal chemical impact on the surrounding environment.

This active substance is primarily used for controlling populations of both commensal and field rodents. It is highly effective against Norway rats, roof rats, and house mice.

In agricultural settings, chlorophacinone is applied to control voles and other small rodents that cause significant damage to crops and infrastructure.

The substance is widely used in grain warehouses, livestock facilities, and surrounding agricultural areas to protect valuable food stocks and feed supplies from destruction.

Chlorophacinone is an ideal choice for managing rodent populations that have developed resistance to first-generation anticoagulants like warfarin.

Due to its stability, it remains effective in humid environments, which is essential for protecting damp warehouses, basements, and sub-floor areas.

Application rates depend on the product formulation: typical ready-to-use baits contain between 0.005% and 0.01% of chlorophacinone. Baits should be placed precisely in areas with clear signs of activity.

For rats, standard dosage is 10–50 grams of bait per bait station. For mice, significantly smaller amounts of 5–10 grams are usually sufficient.

Bait stations should be spaced 5–15 meters apart. Replenishment should continue as long as consumption occurs, indicating that the population is still present.

Deratization can be conducted throughout the year, but it is most effective before rodents begin their seasonal migration into storage buildings.

Continuous monitoring is vital. Once the bait is no longer being consumed over a period of 3 days, it indicates that the infestation has been successfully controlled.

Chlorophacinone is hazardous to domestic pets and livestock. Bait must be placed in tamper-resistant stations to prevent access by non-target animals.

It is strictly prohibited to apply bait directly onto grain or animal feed. Strict separation between treatment sites and food storage areas is mandatory.

Operators must wear personal protective equipment, including gloves, respirators, and protective clothing. Thorough hygiene is required after handling the product.

In cases of accidental ingestion by humans or animals, immediate medical or veterinary attention is required. Vitamin K1 (phytomenadione) serves as the primary antidote for anticoagulant poisoning.

Disposal of remaining bait and carcasses must comply with local regulations, typically involving deep burial or incineration to prevent secondary poisoning of wildlife.
