CONTRAC BLOX is specially formulated with an optimal blend of food-grade ingredients and a small amount of paraffin. The result is a highly palatable, yet weatherable, bait that works well in wet and dry conditions.

Rodents love CONTRAC due to its highly palatable formulation. CONTRAC BLOX has multiple edges that appeal to a rodent's desire to gnaw. Rodents can consume a lethal dose in just one feeding.

Bait shyness is not a problem with CONTRAC because mortality occurs a few days after bait is consumed.

CONTRAC is also less toxic to non-target animals, in both primary and secondary poisoning situations, than other single-feeding anticoagulants. The antidote, Vitamin K1, is readily available and there is a time factor for treatment.
