  • Patent number: 4914854
    Abstract: A device for catching roaches and other insects utilizing an electric shock to catch or kill such insects is disclosed. An electrical integrated circuit utilizing automatic on and off switching is used to enable roaches and insects to enter the device and then periodically shock them and kill them. The design provides safety, efficiency and lower cost without environmental pollution thereby permitting use around small children and pets. The device includes a cover which admits roaches and insects into the device and which includes openings that are sufficiently small to prevent entry of a child's hand or a pet's paws. When the cover is removed, a microswitch automatically cuts the electrical circuit off. The device includes a housing in which is located a conical downwardly and inwardly sloping surface on which is carried a helical pair of conductors connected to the electrical circuit.
