Deaths typically occur between four days and two weeks after rodents begin to feed on the bait.
First generation rodenticide.
Warfarin chlorophacinone and diphacinone are first generation anticoagulant rodenticides.
With first generation anticoagulant rodenticides the rodent has to feed multiple times to get a toxic dose.
Warfarin like the other anticoagulants inhibits the synthesis of vitamin k dependent clotting factors.
Classes of rodenticides anticoagulants.
Both kinds of anticoagulant rodenticides work by preventing blood from clotting.
But if there s lots of food around why would the rodent come back to your bait.
Warfarin is the earliest first generation anticoagulant rodenticide it has been used in a range of rodent baits since it was first introduced in 1947.
Anticoagulants are defined as chronic death occurs one to two weeks after ingestion of the lethal dose rarely sooner single dose second generation or multiple dose first generation rodenticides acting by effective blocking of the vitamin k cycle resulting in inability to produce essential blood clotting factors mainly coagulation factors ii.

3 all outdoor above ground use must be in a bait station intended to be resistant to children and pets.
Both first and second generation rodenticides prevent blood from clotting by inhibiting vitamin k though the second generation products build to higher concentrations in rodents and are therefore more lethal to anything that eats them.
First generation anticoagulants include the anticoagulants that were developed as rodenticides before 1970.
10 most of the single dose rodenticides are not allowed to be marketed to non licensed applicators.
