Our favourite fly sprays and deterrents for horses this summer

How do I keep flies away from horses?

Flies are more than just a nuisance for horses; they can be downright unpleasant. Not only can they cause discomfort, but in some cases, they can spread harmful bacteria, viruses, and parasites. Don’t worry, we’ve got your horse’s back with our amazing range of fly repellents to get them to buzz off. Whether you're after something natural or need a tougher solution, we’ve got just the thing!

How do equestrian fly sprays and deterrents work?

Fly sprays and deterrents don’t generally kill pests. Instead, they work by interfering with the fly’s sensory receptors, which are attracted to the odour of flies. This creates a long-lasting barrier on the horse’s coat, making it difficult for them to locate and land on a horse. However, some of these chemicals can cause irritation or distress to sensitive horses. If this is the case, it may be worth opting for a natural-based solution or feed supplement. There are also a range of physical deterrents available, such as fly masks and fly rugs, which create a barrier between the insects and the horse’s coat.

Leovet Power Phaser Spray

If you’re looking for a no-nonsense, heavy-duty solution, the Leovet Power Phaser Spray is your best bet! Made from an optimised blend of highly effective ingredients, it guarantees a long-lasting solution against horseflies, ticks and all biting and non-biting flies for up to seven hours. It’s also great when it comes to sweat resistance, making it ideal for long summer hacks or lazy days out in the paddock.

NAF Citronella Spray

Looking for something that’s ultra gentle on your horse? Citronella fly sprays are scientifically proven to be one of the most effective treatments against flies and midges. This long-lasting, effective solution is perfect for horses with sensitive skin, and gentle enough for everyday use.

Equimins Fly Repellent Gel Extra Strength

Some horses just don’t like being sprayed - that’s where Equimins Fly Repellent Gel Extra Strength comes in! Packed with a powerful ingredient (try saying Ethyl Butylacetylaminopropionate out loud!), it’s designed to give long-lasting protection against the most determined flies. It’s also a dream to apply to sensitive spots such as around the eyes and ears – ideal for fussy horses and gentle hands alike.
