CONTRAC Rodenticide, with the active ingredient, Bromadiolone, is a fresh tasting, highly compressed pelleted bait that holds up well, particularly in adverse or moist conditions. Made from an advanced formulation process, CONTRAC Rodenticide gets superior rodent acceptance and control, including control of Warfarin resistant rats. Besides its outstanding flavor and a long shelf life, CONTRAC Rodenticide pellets also satisfy a rodent's desire to gnaw. Rats and mice can consume a lethal dose of CONTRAC Rodenticide in just one feeding. Rodents, however, can translocate pellets. Bait shyness is not a problem with CONTRAC baits because mortality occurs a few days after bait is consumed. The antidote, Vitamin K1 is available for treatment. CONTRAC Rodenticide comes in bulk pails.
