Horse Sweet Itch Advanced Immunotherapy

Sweet itch causes severe seasonal itching in susceptible horses and ponies, and immunotherapy offers a long-term management option for severe cases.

Key Facts

Sweet itch is caused by hypersensitivity to Culicoides midge saliva
Up to 5% of horses in the UK are affected, with higher rates in native breeds
Affected horses self-mutilate through rubbing, causing hair loss and skin damage
Physical barriers using sweet itch rugs reduce midge exposure effectively
Allergen-specific immunotherapy can reduce sensitivity over 2-4 years

Welfare Considerations

Sweet itch causes intense, chronic itching during the midge season that significantly reduces quality of life. Self-mutilation from scratching causes secondary infections. Management requires year-round commitment to physical protection and, in severe cases, immunotherapy.

What You Can Do

Fit effective sweet itch rugs before midge season begins (April-October in UK)
Stable midge-sensitive horses at dawn and dusk when Culicoides midges are active
Discuss allergen-specific immunotherapy with your vet for severe, uncontrolled cases
