raThe effectiveness of this 1 box depends on the amount of bait consumed and the rodent population in the area:
Single Feed is Enough: The active ingredient brodifacoum is extremely potent. A rodent only needs to eat 1 small block (a single consumption) to accumulate a lethal dose in its body.
Why Does It Take 3–7 Days? This poison works slowly (delayed action). Rodents do not die instantly so that the rest of the colony does not become suspicious (avoiding bait shyness).
1 Box Capacity: One box of rat poison (usually containing about 4 to 10 bait blocks) theoretically contains a sufficient dose to kill a dozen to dozens of rodents, provided the bait is divided and placed at several points along the paths frequented by the rodents.
Signs of Effective Bait:
If within 2–3 days the bait inside the box is gone or reduced, you only need to wait within the next 3–7 days from the first day the bait was eaten to see the results. Usually, the rodents will die in a weakened state and seek open areas or places near water.
How the Poison Works (Anticoagulant): Box rat bait (usually containing active ingredients such as Brodifacoum or Bromadiolone) works by slowly stopping blood clotting and triggering internal bleeding. This biological process takes several days to deplete the blood clotting factors in the rodent's body, regardless of how large the ingested dose is.
Preventing Bait Shyness: Rat poison is intentionally designed to be slow-acting so that other rodents in the colony do not become suspicious. If a rodent dies on the spot immediately after eating the bait, other rodents that witness it will know the food is poisonous and will refuse to touch it again.
Clean
After placing rat bait containing brodifacoum, you must immediately wash your hands thoroughly to remove any adhering poison residue.
Detailed Material Composition
Active Ingredient: Brodifacoum 0.005%.
Formulation: Block Bait (BB) / Ready-to-Use Block Bait.
Inert Ingredients: The remaining 99.995% of the composition consists of bait materials (usually a mix of cereals/wheat as an olfactory attractant for rodents), a wax binding agent to make it water-resistant and prevent it from breaking down easily in damp areas, and a specific dye (blue/bluish in color) as a visual marker to prevent it from being mistaken for human food or animal feed.
Effects on Rodents
Brodifacoum is a second-generation anticoagulant poison (extremely potent).
Mechanism of Action: This poison enters the digestive system and disrupts the vitamin K cycle in the rodent's body. Vitamin K is essential for producing blood clotting factors.
Physical Effects: Due to the absence of clotting factors, the rodent's blood vessels will slowly leak systematically. The rodent will experience undetected internal bleeding in its internal organs.
Behavioral Effects: Before dying, the rodent will feel extremely weak, experience severe dehydration (feeling very thirsty), and tend to seek water sources or open air (such as drains, ditches, or outdoor areas) to drink before finally dying. This minimizes the risk of the rodent dying in hidden places, such as inside house ceilings.
Consumption Until Death
Single Feed: Brodifacoum has a very high toxicity. A rodent only needs to feed once (a single consumption) in a sufficient amount to receive a lethal dose.
Technically, the LD50 (the dose that kills 50% of the test population) of brodifacoum in rats is very small, ranging from 0.27 mg/kg to 0.30 mg/kg of body weight. With a concentration of 0.005% in the bait, a medium-sized rat only needs to consume a few grams of the Ratgone bait block in one night to accumulate a fatal dose in its body.
Time of Poison Effect (Rodent Death)
Time of Death: Rodents do not die on the spot immediately after consuming the bait. Death usually occurs within a range of 3 to 7 days after the bait is consumed.
Reason for the Time Delay: This delayed action is intentionally engineered into anticoagulant poisons to prevent rodents from experiencing "bait shyness." If a rodent dies shortly after eating, other members of the colony that see it will know the bait is dangerous and will refuse to eat it.
