Abstract
A framework is positioned overlying a mole burrow or passageway and supports a pivotally mounted, non-conductive plate carrying a conductor to complete a circuit to actuate a remote alarm during passage of a mole in the burrow, which thereby raises the conductor to touch a contact and actuate the alarm.
