The Options

Types Explained

Full Face Masks with Ears

These cover the entire head including ears, offering maximum fly protection. Ideal for horses with ulcers that are bothered by flies around the ears and face.

Standard Fly Masks (No Ears)

These cover the eyes and face but leave ears exposed. Suitable for horses that dislike ear coverage, though flies may still target ears.

Fly Masks with Removable Nose

Versatile masks that allow you to remove the nose piece for a more open feel. Good for horses that need gradual desensitization or have nasal sensitivity.

Before You Buy

Key Buying Factors

Fit and Pressure Points

Horses with ulcers may be sensitive around the poll, ears, and nose. Choose a mask with soft padding or fleece binding to avoid pressure, and ensure it's not too tight to prevent rubbing.

Breathability and UV Protection

A breathable mesh prevents overheating and reduces stress, while UV protection shields eyes from sun glare that can cause squinting. Look for masks with high UV ratings.

Ease of Application

Ulcer-prone horses may be head-shy or anxious. A mask that's easy to put on and remove without fussing over buckles or straps will minimize handling stress.

Material Softness

Harsh or stiff materials can irritate already sensitive skin. Opt for masks with soft fleece or padded edges to prevent chafing and encourage acceptance.

Living With It

Care, Cost and Maintenance

Cleaning

Hand wash with mild soap and cool water to preserve fabric softness. Avoid bleach or fabric softeners that can irritate skin. Rinse thoroughly and air dry in shade.

Inspection

Check daily for signs of rubbing or pressure sores. Ulcer-prone horses may develop headshaking from discomfort, so remove the mask if irritation appears.

Storage

Store in a cool, dry place away from direct sunlight to prevent UV damage to the mesh. Keep away from rodents that might chew on the straps.

Pro tip

Our team suggests introducing the mask gradually: let your horse sniff it, then hold it against their face before fastening. Use positive reinforcement to build acceptance, especially for ulcer-sensitive horses that may associate handling with discomfort.

Frequently asked questions

Can a fly mask help with ulcer recovery?

Indirectly, yes. Reducing fly stress and eye irritation can help your horse relax, which supports healing. However, always follow your veterinarian's treatment plan for ulcers.

What if my horse rubs the mask off?

Ensure the mask fits snugly but not tight. A mask with a soft, padded noseband or fleece binding may be more comfortable and less likely to be rubbed off.

Are there masks that don't put pressure on the poll?

Yes. Look for masks with a contoured shape or those that attach to the halter or bridle, avoiding straps over the poll. The Kensington and Rambo masks are good options.

How do I clean a fly mask to avoid irritating my horse's skin?

Use a gentle, fragrance-free soap and rinse thoroughly. Avoid harsh detergents or fabric softeners, and air dry completely before reuse to prevent mold or stiffness.

Can I leave a fly mask on overnight?

It's generally not recommended as masks can shift and cause rubbing. Only use during peak fly hours. Remove at night to allow the skin to breathe and to check for irritation.
