Fight The Flies That Cause Your Cattle Discomfort

ClariFly® Larvicide protects from disease-carrying flies that feed on dairy cattle, including house flies, stable flies, face flies, and horn flies. To most effectively and efficiently control flies on a dairy operation, consider a comprehensive fly control program built on ClariFly® Larvicide.

Impact flies can make on dairy cattle

  • Reduced weight gains
  • Increased stress
  • Livestock bunching
  • Decreased milk production
  • Disease - Mastitis, Pinkeye and BRD

Flies on dairy operations impact cattle health through painful bites and the spreading of diseases. Uncontrolled fly problems on dairy operations can potentially impact neighboring communities. Fly control will not only economically benefit your livestock operation, but also the community at large.

While dairy operations will never be completely free of flies, untreated fly infestations can lead to reduced dairy profitability. In fact, studies have confirmed that the economic threshold for dairy farms is just 50 flies per animal. That’s the point at which the negative effects of flies can cost an operation more in damages than the cost to effectively treat flies on a dairy.

Interrupting The Fly Life Cycle

Nuisance flies are a vector of disease and an irritant to cows on a dairy operation, as well as to the people that work on the operation. To be fully effective, it is important to start ClariFly® Larvicide early in an animal’s life and continue throughout their duration for every animal on the premises.



House flies have been implicated in the transmission of 65 disease organisms.



ClariFly® Larvicide is over 96.7% effective in controlling flies in the treated manure of dairy cattle.

“What I’ve found the best about ClariFly Larvicide is the easiness.”

“You get it, put it in your feed, and it’s over with. By using ClariFly in our feed, it saves us labor and time that we could be doing something else with. I’d drive through a barn with heifers on both sides and just not see any flies. At one point I went and got one of my friends that’s got a farm and I said you’ve got to see this, you aren’t going to believe this.”
