CONTRAC All-Weather BLOX Bromadiolone Rat and Mouse Bait
Control rats and mice with CONTRAC All-Weather BLOX, a weather-resistant bait containing 0.005% bromadiolone for labeled indoor and outdoor placements.
CONTRAC All-Weather BLOX combines a palatable bait formula with durable, easy-to-secure blocks for rat and mouse control. Its 0.005% bromadiolone formulation is a second-generation anticoagulant that supports both infestation cleanouts and ongoing maintenance programs.
Each approximately 1-ounce block contains food ingredients blended with a small amount of paraffin to balance rodent acceptance with resistance to damp conditions. Multiple gnawing edges encourage feeding, while a center hole allows attachment to compatible bait-station rods. The compact blocks fit conveniently into labeled baiting locations.
