Horse Sweet Itch Management

Sweet itch is a chronic allergic skin condition caused by Culicoides midge bites, causing intense pruritus and self-trauma in affected horses.

Key Facts

Sweet itch affects 3-5% of the UK horse population
It is caused by an allergic reaction to proteins in Culicoides midge saliva
Signs include intense rubbing, mane and tail hair loss, skin thickening, and self-excoriation
Full body rugs, fly sheets, and midge-proof stabling at dawn and dusk are effective preventives
There is no cure, but management significantly reduces suffering

Welfare Considerations

Sweet itch causes significant chronic suffering through intense itch and self-mutilation. A committed prevention programme using appropriate rugs, shelter, and topical treatments dramatically reduces the welfare burden.

What You Can Do

Invest in a well-fitting sweet itch rug from early spring
Stable affected horses during peak midge activity at dawn and dusk
Use Culicoides-deterrent fly repellents and barrier products
Work with your vet on immunotherapy options for severe cases
Join sweet itch owner support groups for practical management advice
