Farm Animal Welfare

Cattle Fly Control Summer Welfare

Face flies, horn flies, and stable flies cause significant welfare problems for cattle during summer, reducing grazing time and causing chronic irritation.

Key Facts

Horn flies on cattle can number 1,000-4,000 per animal causing blood loss equivalent to 2 liters daily
Face fly spread pinkeye (infectious bovine keratoconjunctivitis) affecting thousands of cattle annually
Stable flies bite legs causing bunching, reduced grazing, and weight loss
Integrated pest management combines insecticide ear tags, pour-ons, and biological control
Pour-on insecticides provide systemic protection but contribute to environmental persistence

Welfare Considerations

Fly burden causes chronic irritation, blood loss, and disease transmission in cattle during summer months. Effective fly control significantly improves cattle comfort and welfare, reduces disease transmission, and maintains productive performance.

What You Can Do

Implement preventive fly control before summer fly season begins
Use integrated approaches combining multiple methods to reduce resistance development
Monitor fly burdens using validated counting methods to guide treatment timing
