Equine Sweet Itch: Managing Chronic Allergic Skin Condition

Sweet itch, caused by Culicoides midge bites, causes intense itching and self-trauma in susceptible horses year after year.

Key Facts

Sweet itch affects around 5% of horses in the UK and similar climates
Affected horses rub mane and tail raw causing open wounds
Full-body fly rugs significantly reduce midge exposure
Immunotherapy offers long-term relief for some horses

Welfare Considerations

Sweet itch causes chronic distress and physical self-injury. Horses cannot understand or control their compulsive scratching. Proactive management during midge season is essential to prevent welfare deterioration each summer.

What You Can Do

Stable susceptible horses during peak midge activity (dawn and dusk)
Use correctly fitted sweet itch rugs throughout midge season
Consult an equine vet about allergen immunotherapy options
