Abstract
Abstract During its life cycle, the hog louse migrates to the ear of the hog; therefore, an ear tag with dichlorvos resin impregnated strip thereon will kill all the hog lice. A specially designed ear tag has been made to contain the dichlorvos strip or whatever material is desired to be placed therein.
