ABSTRACT:
A method and apparatus for permitting animal pests to exit a structure but preventing such animal pests from returning into the structure is provided. The apparatus includes a cylindrical tunnel having a door within the tunnel biased to extend across the opening of the tunnel in a closed position. Animals may travel in one direction through the tunnel by pushing the door up against its bias. However, the animals are prevented from returning through the tunnel in the opposite direction by the biased tunnel door. The tunnel may be attached to cover a hole in a structure by attaching the tunnel to a cover and attaching the cover to the structure. The tunnel of the present invention may be formed from a wire mesh by a method including forming the wire mesh into a cylindrical shape and attaching a wire mesh door within the wire mesh tunnel.
