Companion Horse: Sweet Itch Advanced Management

Sweet itch (insect bite hypersensitivity) causes severe pruritus in sensitive horses, requiring comprehensive management to prevent self-trauma and improve quality of life.

Key Facts

Sweet itch is caused by hypersensitivity to Culicoides midge saliva, affecting 2-5% of UK horses
Affected horses rub mane, tail, and body against any available surface, causing hair loss and skin trauma
Symptoms appear from spring to autumn, correlating with midge activity
Full-body sweet itch rugs with face and belly protection significantly reduce exposure
Stabling during peak midge activity (dawn and dusk) is the most effective management strategy

Welfare Considerations

Sweet itch causes intense chronic pruritus over an entire season, and affected horses that self-traumatise experience both the original pruritic discomfort and pain from self-inflicted wounds. Without management, welfare deteriorates progressively across each season. A comprehensive management plan combining midge avoidance, rugging, and veterinary treatment for secondary infections substantially improves quality of life.

What You Can Do

Stable sweet itch horses during dawn and dusk midge peaks
Use a well-fitted full-body sweet itch rug covering the belly and face
Apply veterinary-grade insect repellent to exposed skin during turnout
Seek veterinary advice for secondary infections from self-trauma
Consider immunotherapy as a long-term management option for severely affected horses
