CONTRAC Super-Size BLOX is a larger version of Bell's extruded BLOX, which is ideal for sewers and other tough baiting situations. The 8 oz. (225g) BLOX, containing the single-feeding anticoagulant, Bromadiolone, is excellent for clean-out and maintenance control of mice and rats, including warfarin-resistant Norway rats. An all-weather bait, CONTRAC Super-Size BLOX is formulated with the optimal blend of food-grade ingredients and a low wax content to yield a highly palatable and weatherable bait. In stringent weather testing, CONTRAC Super-Size BLOX achieved consistent rodent acceptance. Plus, the Super-Size BLOX is shaped with multi-edges that appeal to a rodent's need to gnaw. This large BLOX fits securely in Bell's larger, tamper-resistant bait stations. A center hole also lets technicians wire or hang it for added security.
