Companion Horse Sweet Itch Advanced Management

Advanced management approaches for sweet itch (Culicoides hypersensitivity) in horses and ponies.

Key Facts

Sweet itch affects 2-5% of UK horses and ponies and causes severe pruritus
The condition is caused by hypersensitivity to Culicoides midge bites
Fly rugs covering the entire body provide significant protection in well-designed products
Stabling during peak midge activity at dawn and dusk reduces exposure substantially
Desensitization immunotherapy is under investigation as a potential treatment approach

Welfare Considerations

Sweet itch causes chronic, intense pruritus leading to self-trauma, hairless patches, and secondary infection. The condition is seasonal but causes significant welfare compromise across the grazing season. Comprehensive management combining barrier protection and exposure reduction is the most effective approach.

What You Can Do

Invest in a full-body Culicoides-proof fly rug for affected horses
Stable affected horses during dawn and dusk when Culicoides are most active
Work with your vet on additional management measures including antihistamines or corticosteroids if needed
