Fly Sprays & Repellents

About

Fly sprays and repellents help keep flies, midges and other biting insects off your horse. They split into stronger synthetic repellents (often containing DEET, for long-lasting protection), gentler natural and citronella formulas , and targeted gels, creams and roll-ons for the face and sensitive areas. Just Horse Riders stocks them from brands including NAF, Carr & Day & Martin, Barrier, Leovet and Gold Label, from around £5.

In a hurry? For long-lasting protection on a hard day choose a DEET-based repellent ; for sensitive horses or daily use a natural or citronella formula is gentler. Use a roll-on or gel around the face and ears, where a spray is not ideal. Which fly repellent do I need? Type Best for DEET-based Strong, long-lasting protection for busy yards and hard days Natural / citronella Sensitive horses and everyday use — gentler, top up more often Gel / cream Targeted protection for the face, ears and sore spots Roll-on Mess-free application around the eyes and muzzle How do I apply fly spray? Spray onto a clean, dry coat from a short distance and smooth it in, avoiding the eyes; use a sponge or roll-on for the face. Reapply as directed — strong repellents last longer, while natural ones usually need topping up more often, especially after rain or sweating. Always patch-test a new product first. What is the strongest horse fly repellent? DEET-based sprays such as NAF Off Deet Power and Flygard Extra Strength are among the longest-lasting. For midges and sweet-itch-prone horses, pair a repellent with a fly rug for a physical barrier.
