Fly Season Solutions

Keeping pests away from your livestock is crucial for their well-being and the biosecurity of your facilities. Elanco can provide you with the information and products you need to help control these pests.

Flies are often an underestimated menace to cattle producers and can significantly impact the wellbeing and profitability of the herd through: 

  • Reduced Weight Gain
  • Reduced Milk Production 
  • Disease Transmission 

Fly infestations cause agitation and discomfort which interrupts grazing resulting in compromised nutrition and production losses.

Yearling weights can be reduced by up to 18%¹ contributing to $1 billion annual losses to the US Livestock producers due to horn flies². Add to this that stable flies cost producers an estimated $2.2 billion annually², and it is evident that flies are more than just a nuisance for the cattle industry.

Managing flies and other pests with a targeted control point approach is an important step. Elanco offers multiple insecticide products to help keep your cattle and facilities clear of flies. Check out our insecticide portfolio to take control.
