Livestock producers need an integrated pest management plan to control the loss of production due to filth flies while cattle graze summer pastures. This may include the movement of livestock, mechanical disruption of grazing areas, mechanical removal of flies and the use of natural and chemical insecticides or repellents.

Since its introduction into the U.S. in the late 1800s, the horn fly has become a persistent challenge for livestock producers in pasture-based systems. For beef and dairy operations, horn flies are more than a nuisance; they contribute to measurable losses in weight gain, milk production and overall animal performance.

Fly control in beef cattle continues to be an in-demand topic each year as the potential resistance to conventional fly tags and the introduction of garlic as a feed ingredient to mitigate flies becomes more prevalent. Fly control management is important to minimize the spread of disease and to minimize the negative impacts on livestock production.

A well-balanced mineral and vitamin program is the foundation for healthy, productive and profitable cattle. However, when specific challenges arise, the strategic use of mineral additives can provide targeted solutions.

The best way to treat flies is to first understand what fly you are treating for. Remember: Face flies are found on the face, stable flies are found on front legs, and horn flies are found on the back and sides.

Discussions of stress are not uncommon in cattle production. A great deal of this discussion is often focused on the stress typical for the weaned/transition calf and its common journey though the U.S. marketing system, which involves a lot of handling and transportation.

Many producers think that when a cow shakes flies off or swats them away with her tail, the issue is over. It isn’t. However, by controlling flies, you can improve cow comfort, lower disease transmission and minimize production losses.
