Overview
If your horse is avoiding turnout when flies are bad, the most common reason is simple discomfort. Flies and midges can make horses restless, itchy and tense, so they may nap at the gate, circle around, or flat-out refuse to go out. It can also be linked to pain, skin irritation or a bad turnout experience, so it’s worth checking the basics rather than assuming it’s just fussiness.
Things To Check
1. Notice whether the reluctance only happens in certain weather, at dusk and dawn, or in still, warm conditions when flies are usually worse.
2. Look closely for itching, tail swishing, stamping, head tossing, rubbing or changes in behaviour when the horse is outside.
3. Check the skin, mane, tail base, face, belly and legs for bites, broken skin, hair loss, scabs or signs of rubbing.
4. See whether the horse is sore when being asked to move, tack up or walk out, as discomfort elsewhere can make turnout feel less appealing.
5. Think about whether the field has shelter, shade, wind or a drier area where your horse can get some relief from insects.
6. Review any recent changes such as a new field, herd mate, rug, feed routine or turnout timing.
7. Notice whether the horse is only reluctant with one type of turnout, for example alone, in a particular field, or after being stabled for longer than usual.
Common Causes
The most common cause is fly and midge irritation. Some horses are much more bothered than others, and a bad swarm can make turnout feel unpleasant very quickly.
Skin sensitivity or sweet itch-type irritation can also make a horse associate turnout with discomfort, especially if the mane, tail, belly or face are getting itchy.
Sometimes the issue is environmental. Fields with little shade, no breeze or high insect pressure can make a horse reluctant to settle outside.
Less commonly, the horse may be linking turnout with another problem, such as soreness, a bad experience in the field, herd stress, or general discomfort that becomes more obvious when they’re asked to move.
What To Do
Start by making turnout as comfortable as you can. If possible, use quieter times of day, offer access to shade or shelter, and avoid turnout when flies are at their worst.
Check the coat and skin daily during fly season so you can spot rubbing, bites or sore areas early. Keeping a simple note of when the reluctance happens can help you see patterns.
If your horse is usually settled but has started refusing turnout, take a step back and think about what changed recently. A new field, new companions or a change in weather can all make a difference.
Handling the situation calmly also helps. If turnout has become a battle, keep the routine low-key and predictable so it doesn’t build into a bigger problem.
When To Contact A Vet
Contact your vet if the reluctance to turnout is new and ongoing, or if you notice obvious pain, marked skin irritation, swelling, open sores, head shaking, severe rubbing, or any sign that your horse is unwell. A vet can help check whether there’s an underlying issue beyond fly irritation.
Products That May Help
