Target rodents with Neogen Ramik Green rodenticide. This weather-resistant rodent bait can be used indoors or outdoors. The rodenticide's active ingredient is the first-generation anticoagulant diphacinone, which triggers rodent death within 4 to 5 days after a lethal dose is consumed. The rodent bait is made with food-quality grain mix and is fish flavored for palatability. Each package contains 4 rodenticide bars. Recommended for commercial use.
