Old Panasonic TV casing with a High Voltage grid is placed over an underground wasp nest. The results are great as the wasps have to go through the grids which are electrified at 5600 Volts DC. <br />The power is furnished by a Microwave oven Transformer and voltage duplexer with Capacitors. <br />I have exploded around 4000 wasps from the nest. <br />I build this device after I was stung last year by about 15 wasps while mowing the lawns. <br />Wasps are a plague in some parts of New Zealand as they have no natural predators and they are affecting our native insects and caterpillars of the Monarch Butterflies. <br />These wasps ( Yellow Jackets ) are very aggressive and are capable of multiple stings at the time.
