Abstract: An entry barrier for a doorway includes a first strip, mechanically coupled to a jamb and a threshold around a strike plate. A second strip is mechanically coupled to the jamb and the threshold around the strike plate and parallel to the first strip. A printed circuit board in a power source unit is electrically coupled to the first strip and the second strip. The printed circuit board directs electrical power from the power source unit to the first strip and the second strip such that a pest contacting the first strip or the second strip is electrocuted.
