One day you were fine; the next day you felt a little feverish and had these raised red bumps all over your body. The worst part was the all-consuming, unrelenting itchiness. All you could think about was scratching this itch here, really getting your nails in there, regardless of the damage it could cause. Maybe your mom even ended up putting mittens on you to prevent scabs.
If your horse has sweet itch, this is the kind of discomfort they are likely experiencing. And unfortunately, it’s hard to put mittens on a horse.
Read on to learn more about sweet itch, what causes it, and the best way to soothe your itchy equine pal’s irritated skin.
Culicoides. Biting gnats. Midges. No-see-ums. The tiny predators that cause sweet itch in horses go by many names, but all lead back to the same horrible result: a rash your horse can’t shake.1
Sweet itch is an intense allergic reaction stemming from one of these nasty gnats. It’s not the bite wound itself; it’s the biting midge’s saliva. Just like how not everyone is allergic to peanuts, not all horses are sensitive to midge saliva. But when they are sensitive, it causes excess histamine to be released in your horse’s bloodstream.
What follows is an intense allergic reaction that won’t quit.
It’s especially tough to stop sweet itch because midge bites are relentless. And there’s a reason sweet itch is often referred to as a seasonal allergy. Culicoides are most active during summertime, when your horse is likely running around (and running into bugs) the most. Repeated bites mean repeated itchiness.
Different species of culicoides bite in different places, but wherever they choose to chomp, your horse will scratch—often to the point of hair loss, open wounds, hardened skin, and other irritations.
Plenty of horses with sensitive skin often break out in rashes from environmental factors. Innocuous bug bites, pollen, fly spray, and even the wrong kind of bedding can cause minor allergies in your sensitive horse. But a generic allergic reaction looks a lot different than the allergic response that results from sweet itch.
“Normal” horse rashes, or those related to common allergens, typically present with:
Rashes that appear from sweet itch present with:
Though sweet itch can affect any horse, the severity of their allergic response can be genetic. If you can get info on your pony’s forbearers, it can help you pinpoint whether or not your horse is predisposed to develop sweet itch.
Likewise, some breeds are more likely to develop a reaction than others.2 If you have a Welsh pony, Icelandic horse, or a Shire, keep your eyes peeled for that intense itching and characteristic hair loss.
There’s nothing sweet about how this rash makes an affected horse feel. But there is something to be said of the sweet relief achieved when proper treatment is applied to midge bites.
There is no immediate cure for sweet itch. Typically, veterinarians will start by performing some diagnostic tests to rule out other causes for the itching by scraping a small skin culture.
The treatment that follows may include steroids, antihistamines, and antibiotics to prevent infection. Omega 3 fatty acids and MSM supplements have been shown to help build up immunity to sweet itch in the future, and long-term remedies include immunotherapy. A vet will help you inject small doses of the allergen in gnat saliva, to build up your horse’s tolerance for the next season.

If you don’t have time for a vet visit, try the next best solution. Your horse will thank you for alleviating the assault of itchiness that those pesky flies bring every season.
Flies aren’t easy to prevent. When you can hardly see the insect, how are you supposed to keep it out of your stable? However, similar to horsefly bite treatment, trying to prevent insects in the first place is a key part of sweet itch treatment. Here are a few ways you can lessen your horse’s exposure to no-see-ums this summer.
One of the best ways to prevent bites (from any insect, not just midges) is to protect your horse’s skin.3 Methods range from full-body sheets to individual fly boots, fly masks, and body covers. Just make sure whatever your horse is wearing is breathable for those hot months. If your horse hates wearing covers, you can also try installing mesh screens or curtains on all barn openings to prevent bugs from flying in.
Eliminate manure and trampled hay as soon as you see it. Keeping your horse’s stable squeaky clean will prevent any biting fly from being attracted to the area. Maintain your horse’s feed and water, too. Still water can be a breeding ground for bugs, including midges and mosquitoes.
Culicoides cannot fly in wind faster than 5 mph.4 So installing a fan in your stable is a great way to prevent these midges from sticking the landing on your horse. Plus, your horse will love a cool breeze through its mane on those scorching days.
When you’re letting your horse explore or taking them on an exhilarating ride, be aware of the popular gnat hangouts and avoid them. These include marshy areas, bogs, and standing water. Even the shady ground under a tree can be gnat city if there is enough rotting vegetation underneath.
In addition, be aware of peak midge hours. Keep your horse stabled at dawn and dusk, when the flies are most active, to prevent bites.
Sometimes, you can practice all the prevention in the world, and your horse still gets bitten. They still break out in hives or sweet itch, scratching away their skin and coat. You can’t protect your horse from everything, but you can help them when they’re experiencing discomfort.
Vetericyn’s FoamCare Medicated Equine Shampoo and Equine Wound and Skin Care Liquid are there to soothe when things get itchy. You don’t always need to go to the veterinarian to get vet-level care for your horse’s skin and coat.
Keep your horse cool and composed in those hot summer months and all year round with Vetericyn.
