Bromethalin vs Diphacinone Rodenticide Safety and Efficacy
Bromethalin is a fast-acting neurotoxin that causes brain swelling in rodents; Diphacinone is a slower vitamin-K-blocking anticoagulant that leads to internal bleeding.
People confuse them because both come in blue-green pellets, are labeled “rodent bait,” and sit side-by-side on shelves; the subtle names feel interchangeable until a pet eats one and panic sets in.
Key Differences
Bromethalin works within hours with no antidote; Diphacinone needs repeated feedings over days but can be reversed with vitamin K therapy.
Which One Should You Choose?
Homeowners after a quick knock-down reach for Bromethalin; professionals managing large infestations often favor Diphacinone for its margin of safety around non-target animals.
Can either poison harm pets?
Yes, both are dangerous; keep all baits in locked boxes and monitor pets closely.
What if my dog eats some?
Call a vet immediately; rapid action improves the chance of recovery.
