Livestock Fly Control and Animal Welfare

Fly strike and fly-borne disease cause significant welfare harm to livestock, requiring integrated management approaches.

Key Facts

Blowfly strike in sheep causes acute tissue damage when larvae hatch under fleece and consume living flesh
A single untreated strike can kill a sheep within days
Face flies in cattle carry pinkeye pathogens that cause painful eye infections
Stable flies inflict painful bites that cause cattle to bunch together and reduce grazing time
Integrated pest management combining preventive and responsive treatments reduces fly welfare impact

Welfare Considerations

Fly-related welfare problems in livestock are among the most acutely painful conditions these animals experience. Blowfly strike in sheep is particularly severe — larvae consuming living tissue while the sheep remains alive causes extreme suffering that may not be detected by farmers checking large flocks infrequently. Face fly transmission of pinkeye causes corneal ulceration, pain, and blindness that can persist for weeks without treatment. Proactive prevention — flystrike protection, timing of shearing, identification of high-risk animals — reduces the incidence of these acutely painful conditions substantially.

What You Can Do
