How to Treat Sweet Itch in Horses
Sweet itch, also known as summer itch or sweet itch disease, is a common skin condition that affects horses during the warmer months. It is caused by an allergic reaction to the saliva of biting midges, which are tiny insects that feed on the horse’s skin. The condition can cause intense itching, leading to skin lesions, hair loss, and secondary infections. In this article, we will discuss the causes, symptoms, and treatment options for sweet itch in horses.
Causes of Sweet Itch
Sweet itch is caused by an allergic reaction to the saliva of biting midges, specifically the Culicoides species. These midges are attracted to the horse’s skin and feed on its blood, leaving behind saliva that contains an allergen. This allergen triggers an immune response in the horse, leading to the characteristic symptoms of sweet itch.

- Redness and inflammation of the skin
Diagnosis of Sweet Itch
Diagnosing sweet itch can be challenging, as the symptoms can be similar to those of other skin conditions. A veterinarian will typically perform a physical examination, take a complete medical history, and conduct diagnostic tests to rule out other conditions. These tests may include:
- Skin scrapings or biopsies to examine for midge saliva and allergens
- Blood tests to check for elevated levels of IgE antibodies, which are indicative of an allergic response
- Elimination diets to rule out food allergies or sensitivities
Treatment Options for Sweet Itch
Treatment for sweet itch typically involves a combination of the following:
Topical Treatments
Topical treatments can provide quick relief from itching and inflammation. These may include:
- Corticosteroid creams or ointments to reduce inflammation and itching
- Antihistamine creams or ointments to relieve itching and reduce the allergic response

- Flea and tick shampoos or sprays to kill midges and other biting insects
In severe cases of sweet itch, systemic treatments may be necessary to reduce the allergic response and relieve symptoms. These may include:
- Corticosteroids, such as prednisone, to reduce inflammation and itching
- Antihistamines, such as hydroxyzine, to relieve itching and reduce the allergic response
- Cyclosporine, an immunosuppressive medication, to reduce the immune response

Some horse owners have reported success with alternative therapies, including:
- Aromatherapy, such as the use of tea tree oil or lavender oil, to reduce itching and inflammation
- Acupuncture or acupressure to reduce itching and alleviate symptoms
- Herbal remedies, such as chamomile or calendula, to soothe the skin and reduce inflammation
Prevention of Sweet Itch
Preventing sweet itch requires a combination of environmental changes, topical treatments, and systemic medications. Some ways to prevent sweet itch include:
- Applying insect repellents or insecticides to the horse’s skin or living area
- Using fans or misting systems to reduce midge activity
