Cattle Fly Control Summer Welfare

Summer fly burden causes significant welfare harm to cattle through irritation, disease transmission, and disruption of grazing behaviour requiring integrated management.

Key Facts

Horn flies cause an estimated 1 billion dollars annual production loss in US cattle
Face flies transmit pinkeye bacteria causing painful ocular disease
Warble fly larvae tunnel through cattle skin causing painful swellings
Ear tags impregnated with pyrethroid insecticides provide season-long fly control
Integration of biological control, pour-on products, and housing management reduces welfare impact

Welfare Considerations

Summer fly burden causes chronic irritation, pain from disease transmission, and disruption of normal grazing behaviour that significantly reduces cattle welfare. Integrated fly management reduces this preventable welfare burden while managing concerns about insecticide resistance.

What You Can Do

Implement fly control programmes matched to local fly species and pest pressure
Use combination approaches including biological control alongside chemical management
Monitor cattle for signs of fly-related disease including pinkeye and treat promptly
