Sweet itch, also known as insect bite hypersensitivity (IBH) or summer eczema, is a recurring seasonal allergic dermatitis in horses caused by hypersensitivity to the saliva of biting midges (Culicoides species). This intensely pruritic (itchy) condition can significantly impact a horse’s quality of life, leading to chronic rubbing, scratching, hair loss, skin thickening, and secondary infections. While there’s no cure for sweet itch, effective management strategies can significantly alleviate symptoms, prevent complications, and improve your horse’s comfort during the midge season.

Understanding Sweet Itch: The Allergic Cascade
Sweet itch is an allergic reaction to the saliva of biting midges, tiny flies that are most active at dawn and dusk during the warmer months. When a susceptible horse is bitten, the midge saliva triggers an immune response that leads to intense itching and inflammation.
- Hypersensitivity: The horse’s immune system overreacts to the midge saliva, releasing histamine and other inflammatory mediators.
- Pruritus (Itching): The release of histamine causes intense itching, leading the horse to rub, scratch, and bite at the affected areas.
- Inflammation: The constant rubbing and scratching cause skin inflammation, leading to redness, swelling, and hair loss.
- Secondary Infections: The damaged skin is more susceptible to secondary bacterial and fungal infections.
Recognizing the Signs: Identifying Sweet Itch Early Recognizing the signs of sweet itch is crucial for initiating timely management strategies. Common symptoms include:
- Intense Itching: Excessive rubbing, scratching, biting, or licking of the skin, particularly along the mane, tail head, back, and belly.
- Hair Loss: Patches of missing hair, often due to rubbing and scratching.
- Skin Thickening (Lichenification): Thickening of the skin due to chronic irritation.
- Scaling and Crusting: Dry, flaky skin or the formation of crusts.
- Self-Trauma: Open sores or lesions due to self-trauma from rubbing and scratching.
- Secondary Infections: Signs of secondary bacterial or fungal infections, such as pus, odor, or increased inflammation.
- Restlessness and Irritability: The horse may be restless, irritable, or difficult to handle due to the intense itching.
- Seasonal Pattern: Symptoms typically appear during the warmer months when midges are active and subside during the colder months.
Management Strategies: A Multifaceted Approach Managing sweet itch requires a multifaceted approach that focuses on reducing exposure to midges, alleviating itching, and preventing secondary infections.
- Reduce Exposure to Midges:
- Stabling During Peak Midge Activity: Stable your horse during dawn and dusk, when midges are most active.
- Use Fans: Use fans in the stable to create a breeze that midges cannot easily fly in.
- Fly Screens: Install fine-mesh fly screens on stable windows and doors.
- Avoid Midge-Prone Areas: Avoid grazing your horse near ponds, marshes, or wooded areas, which are breeding grounds for midges.
- Protective Clothing:
- Sweet Itch Rugs: Use a sweet itch rug that covers the horse’s entire body, including the mane, tail, and belly.
- Fly Masks: Use a fly mask with ear and nose protection.
- Topical Insect Repellents:
- Apply insect repellents specifically designed for horses to repel midges.
- Reapply frequently, especially after rain or sweating.
- Topical Treatments to Alleviate Itching:
- Use topical treatments to soothe irritated skin and reduce itching.
- Common topical treatments include:
- Corticosteroid creams: To reduce inflammation and itching.
- Antihistamine creams: To block the effects of histamine.
- Soothing lotions: Containing ingredients such as aloe vera, chamomile, or oatmeal.
- Medications:
- In severe cases, your veterinarian may prescribe medications such as:
- Corticosteroids: To reduce inflammation and itching.
- Antihistamines: To block the effects of histamine.
- Administer these medications according to your veterinarian’s instructions.
- In severe cases, your veterinarian may prescribe medications such as:
- Hyposensitization (Allergy Shots):
- Hyposensitization involves injecting the horse with small amounts of midge antigens to gradually desensitize the immune system.
- This treatment is not always effective, but it can provide relief for some horses.
- Dietary Management:
- Ensure that your horse is receiving a balanced diet that supports a healthy immune system.
- Consider supplementing with omega-3 fatty acids, which can help to reduce inflammation.
- Treat Secondary Infections:
- If your horse develops a secondary bacterial or fungal infection, treat it promptly with appropriate medications prescribed by your veterinarian.
Prevention Strategies: Minimizing the Risk While sweet itch cannot be completely prevented, you can minimize the risk by:
- Selecting Resistant Breeds: Some breeds are more resistant to sweet itch than others.
- Early Management: Implement management strategies early in the season, before symptoms become severe.
- Consistent Routine: Maintain a consistent management routine throughout the midge season.
- Environmental Control: Focus on controlling the midge population in your horse’s environment.
When to Call the Vet: Seeking Professional Guidance It’s important to consult your veterinarian if:
- Your horse is showing signs of sweet itch.
- The symptoms are severe or persistent.
- Your horse develops a secondary infection.
- You are unable to manage the symptoms effectively
