Horse Sweet Itch: Prevention and Advanced Management

Managing the severe welfare impacts of sweet itch in horses through comprehensive prevention strategies.

Key Facts

Sweet itch is an intensely pruritic skin condition caused by hypersensitivity to Culicoides midge bites
Affected horses can cause self-inflicted wounds and hair loss from constant rubbing
Rugs with fine mesh effectively reduce midge exposure when used consistently from dawn to dusk
Immunotherapy is available and produces lasting improvement in some sweet itch cases

Welfare Considerations

Sweet itch causes chronic, severe pruritus that dominates affected horses' summer welfare. The condition is incurable but manageable, and horses with poor management experience unnecessary suffering during midge season year after year. Comprehensive prevention combining protective rugs, stabling at midge times, and veterinary management significantly reduces welfare impact.

What You Can Do

Use a properly fitted sweet itch rug consistently during midge-active periods
Stable affected horses at dawn and dusk when Culicoides midges are most active
Discuss immunotherapy with an equine vet for horses with severe or poorly controlled sweet itch
