🏷️ Brand Names — Same Active Ingredient

⚠️ Don't buy duplicates. All products below contain diphacinone 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

Diphacinone is a first-generation anticoagulant — the original class of anticoagulant rodenticides. It requires multiple feedings over several days to achieve a lethal dose, unlike second-generation anticoagulants (bromadiolone, brodifacoum) where a single feeding is sufficient.

Lower secondary poisoning risk: Because diphacinone requires multiple feedings and is metabolized more rapidly, the risk of secondary poisoning to raptors, pets, and predators is significantly lower than second-generation products. Many integrated pest management programs prefer diphacinone precisely because of this.

⚗️ Mixing & Application Rates

Ready-to-use. Tracking powder formulations (0.1%) are restricted-use in many applications — verify state requirements.

Rat control — bait stations

4–8 blocks per station

Requires multiple feedings — maintain fresh bait continuously for at least 2 weeks. Replace any bait that becomes wet, moldy, or contaminated. Lower secondary poisoning risk than second-gen products.

Mouse control

1–3 blocks per station

Place stations every 8–12 feet along active runways. Requires 3–7+ days of feeding for lethal dose accumulation.

Example

0.5 oz

per gallon

⚠️ Safety & Precautions

Lower secondary poisoning risk than bromadiolone or brodifacoum — a key advantage in wildlife-sensitive areas
Antidote: Vitamin K1 (same as all anticoagulants)
Tamper-resistant bait stations required for outdoor use
Tracking powder formulations (0.1%) require additional PPE and applicator precautions
Keep away from children and non-target animals

❓ Frequently Asked Questions

Q: Is diphacinone safe for pets?

Follow the product label. Keep pets out of treated areas until completely dried (2–4 hours for sprays). Once dry, treated surfaces pose minimal risk to dogs and cats.

Q: Can I use diphacinone 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 diphacinone 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.
