Your Horse Deserves a Fly Free Summer. Get prepared with the best defence against fly season.

We know how annoying flies, midges and biting insects are throughout the season. Protection from flies is an essential part of horse care as they can irritate and spread diseases.

Our vet-approved guide explores the most effective and popular fly sprays, carefully selected by our equine experts, to help you choose the right product to protect your horse.

Heavy Duty Fly Sprays

These are best suited to horses that are exposed to high levels of flies, particularly those in open turnout, near water or woodland and in peak summer conditions. They contain stronger active ingredients so offer longer lasting protection.

Vet Recommendations

Leovet Power Phaser Fly Protection

NAF Off Deet Power for Horses

Carr & Day & Martin Flygard Extra Strength

Natural & Sensitive Skin Fly Sprays

These are best suited to horses with sensitive skin or owners looking for a gentle, plant-based alternative. They require more frequent application, so are most effective with consistent use or when combined with fly rugs or masks.

Other Ways To Protect

Many owners choose to support protection by combining topical products with physical barriers and good environmental management.

Gels

Ideal for targeted protection, particularly around the face, muzzle, legs and sensitive areas where spray may be difficult to apply or wear off easily.

Rugs

Provide a physical barrier that helps prevent insects from landing on their body, making it one of the most effective long term fly control solutions.
