Choose a fine-mesh rug that covers the areas your horse needs, with a good fit, secure straps and UV protection. Add a belly flap and neck cover for sweet-itch horses, and pick breathable, durable fabric.
Match coverage to the need
A basic fly sheet covers the body, but horses prone to sweet itch or belly bites benefit from full coverage: a fitted neck, a belly flap and a tail cover. Decide what your horse needs before choosing, since more coverage means more protection but also more rug to manage.
Mesh and fabric
Look for a fine, tightly woven mesh that stops small biting midges, not just larger flies, along with breathability so the horse does not overheat. Durable fabric matters, as fly rugs take a beating in the field, and UV protection adds sun defence for pink-skinned horses.
Fit is everything
A fly rug that slips or gaps lets insects in and rubs the horse. Measure your horse and choose the right size, check the depth and neck fit, and look for secure, adjustable straps. A well-fitted rug stays put and protects, while a poor fit causes sores and frustration.
Pair with other defences
Even the best rug leaves the face and legs exposed, so combine it with a fly mask and a repellent spray on uncovered areas. Together these form a barrier flies struggle to get past.
Care for the rug
Rinse and clean the rug regularly so mesh stays breathable and to remove sweat and dirt that attract flies. Check daily for tears, slipped straps and rubs, and repair or replace as needed so protection stays complete through the season.
