πŸ”¬ How It Works

Brodifacoum is the most potent anticoagulant rodenticide available β€” approximately 100 times more toxic to rats than warfarin. Like all anticoagulants, it inhibits Vitamin K-dependent blood clotting. Death occurs from internal hemorrhage 4–7 days after a single lethal feeding.

Important: Because of its extreme persistence in body tissue and extremely high secondary poisoning risk, brodifacoum should be used only when other rodenticides have failed or resistance is confirmed. Many pest control professionals prefer bromadiolone or diphacinone for routine use, reserving brodifacoum for persistent infestations.

βš—οΈ Mixing & Application Rates

Ready-to-use bait blocks. Never crush or dissolve. Tamper-resistant bait stations mandatory.

Standard rat control
2–4 blocks per bait station
Place in tamper-resistant stations every 15–30 feet along active runways. Check every 3–5 days. Due to extremely high secondary poisoning risk, remove dead rodents promptly and dispose in sealed bags away from raptors.

⚠️ Safety & Precautions

  • Extreme secondary poisoning hazard β€” barn owls, hawks, eagles, foxes, coyotes, cats, and dogs are highly susceptible to brodifacoum from eating poisoned rodents
  • Never use loose baiting β€” tamper-resistant stations are legally required for all outdoor use
  • Remove dead rodents promptly to reduce raptor and scavenger exposure
  • Significantly higher secondary poisoning risk than bromadiolone β€” consider bromadiolone first
  • Antidote: Vitamin K1 β€” requires veterinary administration for pets
