The Livestock Insect Workers Conference (LIWC) is a professional society of veterinary entomologists and industry experts in North America who conduct research on animal ectoparasites including mites, ticks, lice, and biting flies or who otherwise work to control these pests.  The LIWC also serves to disseminate information about new products or novel methods to control these pests.  Members of the LIWC hold an annual conference to share knowledge and address issues related to control of animal ectoparasites.
