Bromethalin

🏷️ Brand Names — Same Active Ingredient

⚠️ Don't buy duplicates. All products below contain bromethalin as the active ingredient. Buying two different brands is buying the same pesticide twice — they differ only in price, concentration, and formulation type.

🔬 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.

Rat control — bait stations

2–4 blocks per station

Faster kill than anticoagulants (1–4 days). May reduce bait shyness. Place in tamper-resistant stations along active runways. Due to no antidote, use with extreme caution in homes with pets.

Mole control (Talpirid)

1 bait worm per active tunnel

Talpirid is a different bromethalin formulation shaped like a earthworm. Place into active mole tunnels. Different concentration (0.025%) than rat bait — do not substitute.

⚠️ 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

❓ Frequently Asked Questions

Q: Is bromethalin safe for pets?

Bromethalin has significant mammalian toxicity. Keep all pets away from treated areas. Contact your vet or ASPCA Poison Control (888-426-4435) if ingested.

Q: Can I use bromethalin indoors?

Check the specific product label — formulations vary. Baits and dusts often have indoor labeling; concentrates and granulars are typically outdoor.

Q: How long does bromethalin last after application?

Residual varies by formulation, surface type, weather, and UV exposure. Indoor applications last longer than outdoor. Check the product label for re-application intervals.

Q: What should I do if exposed?

Remove contaminated clothing, wash skin with soap and water. For eye contact, rinse 15–20 minutes. For ingestion or severe symptoms, call Poison Control (1-800-222-1222). Have the product label available.
