Abstract: Rodent shields are constructed from various gauge metal and are shaped to fit substantially flush against vertical members to prevent roof rats (Rattus Rattus) from traveling to and from their homes located in the upper parts of structures. The rodent shield can be installed on different diameter size vertical members by simply cutting the housing portions at the required length. The rodent shield is wide and the surface is sleek to prevent roof rats from firmly gripping the shield. The rodent shield can be used individually or used with multiple rodent shield.
