CONTRAC Super-Size BLOX is Bell's large extruded BLOX, ideal for sewers and other tough baiting situations. The 8 oz./225g BLOX contains the single-feeding anticoagulant, Bromadiolone, which is less toxic to non-target animals in primary and secondary poisoning situations than other single-feeding anticoagulants. An all-weather bait, CONTRAC Super-Size BLOX is fomulated with the optimal blend of food-grade ingredients and a low wax content to yield a highly palatable, weatherable bait. In stringent weather testing, CONTRAC Super-Size BLOX achieved superior 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.
