US Patent 8387305 Rodent management system having a housing with an entry opening

A rodent management station includes a housing having a base and a lid together at least in part defining an interior space. The housing has an entry opening and an internal partition structure configured to partition the interior space of the housing into a bait chamber having an entryway spaced from the entry opening. A pathway is defined at least in part by the partition structure and extends away from the at least one entry opening to the entryway of the bait chamber. The partition structure has at least one through-opening therein other than at the bait chamber entryway to provide open communication between the pathway and the bait chamber other than at the bait chamber entryway. The at least one through-opening is sized substantially smaller than the housing entry opening and the bait chamber entryway to inhibit rodents against entering the bait chamber at the at least one through-opening.
