A vast range of veterinary chemical products are used in the animal health sector. Those that control external parasites (ectoparasites) on domestic animals are known as ectoparasiticides and comprise two major groups—pesticides and systemic insecticides/acaricides. Ectoparasites of companion animals are a major cause of dermatologic problems in animals and act as vectors for various pathogens. Ectoparasites cause production losses in food-producing animals that incur enormous costs to the livestock industry. The manifestations of ectoparasites on food-producing animals include anemia; reduced production of meat, milk, and eggs; reduced quality and quantity of fleece; damage to hides (cattle grubs and cockle of sheep pelts from lice infestations); hypersensitivity reactions (to the itchmite Psorergates ovis of sheep); transmission of animal diseases (pinkeye of cattle, encephalitis of horses, anaplasmosis of cattle); and decreased resistance to other diseases. Presently, chemical treatment applied prophylactically, strategically, or tactically remains the main option for ectoparasite control.
