Managing Sweet Itch: Treatments & Preventative Tips

Helping your horse stay comfortable during midge season

Sweet Itch is a common condition that affects many horses during the warmer months. Caused by an allergic reaction to midge bites—especially those from Culicoides species—it leads to intense itching, hair loss, and skin damage. While Sweet Itch can’t be cured, it can be managed effectively with a combination of treatments and preventative strategies.

What Does Sweet Itch Look Like?

• Excessive rubbing of the mane, tail, legs or belly

• Loss or breakage of hair

• Thickened or sore skin

• Open wounds or scabbing from self-trauma

• Restlessness, tail swishing, or rubbing against posts, trees or stable walls

Early signs often appear in spring, with symptoms peaking during the height of summer.

Treatment Options

Once symptoms appear, managing irritation and inflammation is key. Some options include:

• Soothing shampoos and creams – to calm the skin and reduce itching

• Fly repellents and barriers – to reduce bites and further reactions

• Rugs and fly sheets – particularly those designed for Sweet Itch, with full coverage including belly and neck

• Supplements – such as omega oils and skin-support nutrients that may help support the skin barrier and immune system

• Environmental management – avoiding high-risk turnout areas near standing water or dense hedgerows where midges breed

Some horses may benefit from more advanced treatments, so it’s always worth discussing options with your vet if symptoms are persistent or severe.

Prevention Tips

Preventing bites is the most effective way to avoid Sweet Itch flare-ups. Here are a few tried-and-tested tips:

• Stable during peak midge hours – usually dawn and dusk

• Use fly screens or fans – to reduce midge presence in stables

• Apply fly repellents regularly – check that they’re safe for sensitive horses

• Keep fields well-drained – and avoid turning out near ponds, streams, or boggy ground

• Regular grooming – to check for early signs and keep the coat clean

Final Thoughts

Sweet Itch can be a challenge to manage, but with a consistent routine and early intervention, most horses can remain comfortable throughout the season. The key is combining good prevention with supportive care when needed.
