Horse Sweet Itch Management

Sweet itch causes intense itching in horses allergic to Culicoides midge bites; effective management significantly improves quality of life.

Key Facts

Sweet itch affects approximately 5% of the UK horse population
The condition is caused by hypersensitivity to proteins in Culicoides midge saliva
Affected horses scratch constantly against fencing, causing skin wounds and hair loss
Eczema rugs and fly masks provide physical barrier protection
Injectable Culicoides allergen immunotherapy reduces sensitivity over time

Welfare Considerations

Sweet itch causes severe chronic suffering characterised by intense, unrelenting pruritus that prevents normal behaviour, disrupts sleep, and causes progressive skin damage. Without effective management, affected horses experience significant welfare deficits throughout the midge season. Comprehensive management combining barrier protection, midge avoidance strategies, and immunotherapy achieves good welfare outcomes for many horses.

What You Can Do

Consult an equine vet for diagnosis and management plan for sweet itch
Invest in well-fitted sweet itch rugs covering neck and belly
House affected horses during peak midge activity at dawn and dusk
