Summer Horse Welfare: Fly Control, Shade, and Heat Management

Summer brings specific welfare challenges for horses including fly irritation, heat stress, and sunburn that require proactive management.

Key Facts

Horses can suffer serious welfare impacts from fly and insect irritation throughout summer
Sweet itch caused by midge bites affects approximately 5% of horses in the UK and causes intense pruritus
Horses with pink unpigmented skin are susceptible to sunburn on muzzle and facial areas
Horses on summer pasture require access to shade, particularly during peak temperature hours
Laminitis risk increases in spring and summer from high-sugar pasture grass

Welfare Considerations

Summer fly irritation causes significant welfare harm to horses through constant disturbance that prevents rest, feeding, and normal behaviour. Horses with sweet itch experience such intense itching from Culicoides midge reactions that they may self-injure through rubbing against fencing and trees. Sunburn on depigmented skin causes painful ulceration that, without treatment, progresses to secondary infection. Heat stress in horses that cannot find shade or reduce activity causes hyperthermia and dehydration. Proactive summer management through fly protection, shade provision, turnout adjustment during peak temperature periods, and skin protection addresses these welfare problems before they become severe.

What You Can Do

Provide fly rugs, masks, and repellents for horses affected by fly irritation
Ensure horses on summer pasture have consistent access to natural or artificial shade
Apply high-SPF sunscreen to pink-skinned muzzles and facial areas during sunny weather
Time turnout to avoid peak biting midge activity at dawn and dusk for sweet itch horses
Monitor body condition and hydration during hot weather and provide electrolytes if sweating heavily
