The system for managing bird populations includes a drone; a disruptor comprising an extension arm having a proximal end and a distal end, the proximal end being operatively coupled with the drone, and the distal end comprising a tool portion, where the tool portion comprises a piercing element constructed for engagement with one or more eggs in a nest; and a remote control system. The remote control system may comprise one or more remote control units and a monitor.

The system can be used to manage bird populations by flying the drone above a bird's nest; positioning the drone above the bird's nest; and descending the drone to disrupt eggs in the bird's nest with the disruptor.

In some examples, a trap to electrocute a pest may include a logic board. The logic board may create an open circuit using two electrical contacts in touch with two conductive plates in a container located in the trap. A pest entering the container may touch the two conductive plates, causing the circuit to close. Based on determining that the circuit was closed, the logic board may determine that a pest entered the trap. The logic board may cause a shutter inside the trap to move from an approximately horizontal position to an approximately vertical position, thereby causing a portion of a door of the container to close by causing two latch strikes of the door to engage with the two jaws of the container. The circuit may send a wireless notification message, indicating that the pest was captured in the container, over a wireless network to a computing device.

A soil disinfector comprising an insulating endless belt with at least one row of positive electrodes and at least one row of negative electrodes mounted on the endless belt. The electrodes are mounted with their heads on the inside of the belt and their bodies pointing outward from the belt, the electrodes being configured to penetrate the soil. The electrodes take their power from a power source, the power source being connected to the electrodes via sets of rows of rollers and sets of rows of stationary conductive contact plates, at least one set of each being positive and at least one set of each being negative. The soil disinfector also has sensors to detect soil conditions and a processor to alter power applied to the soil based on the soil conditions.
