Ectoparasite control can be one of the most expensive and time consuming parts of being a livestock farmer. It is important to raise healthy animals for food and supplies. When working hard to prevent and fight ectoparasites from harming livestock, many factors need to be considered, such as, the time of year, the type of animal and the conditions where it lives and is raised. It is important to realize that ectoparasites are not only an annoyance; they can also transmit diseases and have an impact on the bottom line.
