🔬 How It Works
Bromethalin is a neurotoxic rodenticide — it works by an entirely different mechanism than anticoagulants. Bromethalin uncouples oxidative phosphorylation in nerve cells, causing cerebral edema (brain swelling) and death within 1–4 days — faster than anticoagulants. It is effective against rodents resistant to anticoagulants.
No antidote: Unlike anticoagulant rodenticides (Vitamin K1 antidote), there is no antidote for bromethalin. This is a critical consideration in households with dogs or cats. Prompt veterinary care (inducing vomiting, activated charcoal) must begin within hours of exposure.
⚗️ Mixing & Application Rates
Ready-to-use bait only. Never dilute or modify. Tamper-resistant stations required outdoors.
⚠️ Safety & Precautions
- NO ANTIDOTE — if a pet ingests bromethalin, contact emergency veterinary care immediately. Induced vomiting and activated charcoal within 2 hours may reduce absorption
- Extremely dangerous to dogs and cats — no Vitamin K1 treatment works for bromethalin
- Consider anticoagulant rodenticides in pet-present environments
- Secondary poisoning risk exists but is lower than anticoagulants
- Store in original packaging away from children
