Cattle Fly Control Summer Welfare

Fly burden in summer cattle causes significant welfare harm through irritation, blood loss, disease transmission and behavioural stress.

Key Facts

Horn flies can burden cattle with thousands per animal causing severe irritation
Face flies transmit pink eye (infectious bovine keratoconjunctivitis)
Warble fly is now eradicated from the UK but remains a threat to reintroduce
Fly worrying causes behavioural distress, bunching and reduced grazing time
Integrated approaches including pour-ons, ear tags and environmental management are most effective

Welfare Considerations

Heavy fly burden causes chronic welfare harm through persistent irritation, blood loss causing anaemia in severe cases, and disease transmission. Behavioural disruption from fly avoidance reduces grazing efficiency and causes stress. Integrated fly control that reduces chemical inputs while maintaining welfare protection is the ideal management approach.

What You Can Do

Implement strategic fly control starting before fly season peaks
Use integrated approaches combining environmental and chemical control
Monitor fly levels and welfare indicators to optimise treatment timing
