It is manufactured with a fine particle matrix of ground, high quality cereal grain, cast in moulds with even distribution of the active and the bait. This allows greater durability than conventional compression moulded blocks, which typically contain large cereal grain particles. Attractive to rodents, the high palatability encourages sufficient consumption for the single-feed kill. It is ideal for use in baiting rodent burrows, buildings, grain and food stores, as well as wet environments, including sewers and drains. The central hole in each block allows them to be easily secured in baiting stations and prevents rodents carrying them away.
