An apparatus (10; 110) for preventing vermin or rodent (24) access to buildings through drainage conduits. The apparatus (10; 110) comprises: a duct (12) defining a flowpath and a barrier (16; 116) which prevents access to vermin or rodents (24) through the drainage conduit. The barrier (16; 116) includes a protective structure (165) to deter vermin gnawing the through the barrier (16; 116). The barrier (16; 116) is movable between a flowpath closed position in which the flowpath is substantially closed and a flowpath open position in which the flowpath is substantially open. The barrier (16) is biased to the flowpath closed position by a threshold force. As such the barrier (16) is movable to the flowpath open position upon application of a force greater than the threshold force. The threshold force is sufficient to maintain the barrier (16; 116) in the flowpath closed position under its own weight.
