Horse Sweet Itch Advanced Management

Sweet itch is a chronic allergic dermatitis in horses caused by Culicoides midge bites, causing severe welfare harm through intense pruritus and self-trauma.

Key Facts

Sweet itch affects up to 5% of horses in the UK with native breeds particularly susceptible
Affected horses rub mane and tail areas causing hair loss, skin thickening and self-trauma
Midges are most active at dawn and dusk requiring targeted housing and management
Equine sweet itch rugs with fine mesh provide physical barrier protection
Immunotherapy desensitisation has shown efficacy in reducing allergic response over time

Welfare Considerations

Sweet itch causes intense, chronic pruritus causing significant welfare harm through self-trauma, sleep disruption and behavioural changes. Management requires a multi-modal approach combining physical midge barriers, environmental management and medical support. Immunotherapy offers the possibility of modifying the underlying allergic response.

What You Can Do

Use Culicoides midge barrier rugs and fly repellent on affected horses during peak midge times
Stable horses during dawn and dusk midge activity periods in summer
Discuss immunotherapy options with your vet if conventional management is insufficient
