    Learn how to effectively manage all the species of flies frequently found on dairy farms.

    ORANGE CITY, Iowa – The I-29 Moo University 2021 Dairy Webinar Series continues Friday, March 26 from noon to 1 p.m. This month’s topic is fly control strategies.

    Roger Moon, retired veterinary entomology expert from the University of Minnesota, will identify common pest flies and how to manage them in confinement dairies.

    “Different kinds of flies can bother your cows, workers, and neighbors,” said Fred Hall, dairy specialist with Iowa State University Extension and Outreach. “Stable flies bite, cause cows to bunch, reduce milk production, breed mainly in soiled cow and calf bedding, and pretty much stay on the premise. House flies breed in wetter manure, annoy people, and spread off premise to bother neighbors.”

    According to Hall, routine premise sprays and fogs can keep numbers of both kinds low in confined spaces, but targeted source reduction through debris management outdoors is a more sustainable approach. Moon will discuss these issues and provide time for participants to ask questions.

    Moon retired from University of Minnesota’s Entomology Department in 2016 after 36 years of service in research, teaching, and outreach in veterinary entomology. He continues to study and publish on the biology, ecology, and management of filth flies and other arthropods that occur around livestock, wildlife, and people. 

    Preregistration for the webinar is required; however, there is no registration fee. Register at https://z.umn.edu/flycontrolstrategies.
