Difenacoum is a multi-feed, synthetic, second-generation anti-coagulant rodenticide.
The active ingredient is formulated on a food base, typically cereal, to produce a ready to use bait containing 0.005% w/w difenacoum.
When compared to other anticoagulant rodenticides, difenacoum has a good level of activity against the brown rat, and excellent levels of activity against mice.
Due to the potency of difenacoum to rodents as compared to other non-target species, this active ingredient is particularly useful where domestic or farm animals are present in the area to be treated.
However, difenacoum is a potent poison to all mammal species and it is essential that all baits should be well protected from non-target animals. The best way to achieve this is by placing the baits in an approved bait box.
As with all anticoagulants, accidental poisoning with difenacoum can be antidoted with vitamin K1
Difenacoum is our preferred rodenticide because of its effectiveness against rodents and its slightly less aggressive characteristics against non-target species than most other rodenticides in common use.
