  • Patent number: 5004446
    Abstract: Substances are blown out along the natural wind toward the injurious bees, or group of other insects, for attracting them to an electric grid where a low voltage causes them to deposit venom on the bare wires of the grid and collected on receiving plates. Then the voltage is increased electrocuting them. The venom is removed from the receiving plates and the dead bodies of the bees or other insects are removed from a collecting bag. The device can guarantee the safety of the operating personnel and consists of two parts: an operating compartment and a collection unit. The device can be moved by its own or external effort in order to safely pursue and be close to the injurious bee colony and to operate continuously for a long period. With this device, the propagation or spread of the injurious bees can be controlled and venom be collected safely.
