Horse Sweet Itch Management and Welfare

Sweet itch (equine insect bite hypersensitivity) causes intense seasonal pruritus in affected horses, severely impacting welfare without management.

Key Facts

Sweet itch is a hypersensitivity to Culicoides midge bites affecting up to 5% of horses
Affected horses rub intensely, causing hair loss, skin trauma, and secondary infection
Protective rugs covering the body and belly reduce midge exposure significantly
Stabling during dawn and dusk (peak midge activity) reduces bite load
Immunotherapy and novel biologics offer emerging treatment options for severe cases

Welfare Considerations

Sweet itch causes a seasonal welfare crisis for affected horses - the compulsive rubbing and skin damage caused by hypersensitivity represents significant suffering. Comprehensive management combining midge avoidance and protective clothing can transform quality of life.

What You Can Do

Fit sweet itch-prone horses with whole-body protection rugs during midge season
Stable horses during peak Culicoides activity at dawn and dusk
Discuss allergen immunotherapy with your vet for severely affected horses
