Neogen Rodenticide 40-Pack Havoc Mouse and Rat Killer
The most effective, the easiest to use and the safest rat poison is NEOGEN RODENTICIDE 40-Pack Havoc Mouse and Rat Killer. The active ingredient is brodifacoum, which is a highly effective anticoagulant. In case of accidental poisoning, it responds well to the antidote Vitamin K. This poison is contained within a sealed package, and it is visibly marked as a poison. Rats gnaw through the package to get at the pellets. This method of distribution makes it safe to use, but it still must be concealed from children and pets for maximum safety. Rats will perish after one feeding.
