Abstract: The present invention is relates to a tool for killing lice eggs comprising a body having proximal and distal ends and a comb comprising a first plurality of conductive tines alternating with a second plurality of conductive tines. A plurality of openings are defined by adjacent ones of the first and second plurality of conductive tines, wherein a width of the plurality of openings is less than or equal to 0.2 mm. A first electrical circuit is provided in electrical communication with the comb, the electrical circuit adapted to generate a potential difference between the first and second plurality of tines.
