A Practical Guide for Comfort, Insect Control and Heat Awareness

Many owners assume rugs are only for winter. In reality, summer rugging plays a critical role in protecting horses from insects, sun exposure and skin irritation. However, incorrect summer rug use can lead to overheating, sweating and coat damage.

Summer rugging is about protection — not insulation.

This guide explains when summer rugs are necessary, how to choose correctly, and how to balance fly protection with temperature regulation.


Why Summer Rugging Exists

Summer rugs are primarily used to protect against:

  • Flies
  • Midges
  • Horseflies
  • UV exposure
  • Dust irritation

For some horses — particularly those prone to sweet itch — summer rugging becomes essential for welfare.

However, not every horse requires a summer rug.

Observation and individual need matter.


1. Understanding Fly Rugs

Fly rugs are:

  • Lightweight
  • Mesh-based
  • Breathable
  • Non-insulated

They are designed to create a physical barrier between insects and skin.

A well-fitted fly rug:

  • Reduces biting irritation
  • Minimises tail rubbing
  • Decreases stress behaviours
  • Protects coat condition

2. When Does a Horse Need a Fly Rug?

Fly rugs are especially useful for horses that:

  • Rub mane and tail excessively
  • Develop sweet itch
  • Become agitated by insects
  • Live in midge-heavy environments
  • Have sensitive or thin skin

Some horses tolerate insects well and may not require rugging.

Avoid rugging purely out of habit.


3. Sweet Itch and Specialist Rugs

Sweet itch is an allergic reaction to midge saliva.

In these cases:

  • Full-coverage rugs are essential
  • Belly flaps provide crucial protection
  • Neck covers reduce mane damage
  • Early season use is critical

Prevention works far better than late intervention.

Once severe rubbing begins, skin damage escalates quickly.


4. Heat Considerations

Summer rugs can trap heat if poorly designed or used incorrectly.

Watch for:

  • Sweating under the rug
  • Damp coat
  • Lethargy
  • Increased drinking
  • Reduced grazing

Even breathable mesh slightly reduces airflow.

On very hot days (around 25°C+), consider:

  • Removing rugs during peak heat
  • Turning out overnight instead
  • Providing ample shade
  • Using fly masks or shelters

Comfort always overrides routine.


5. UV Protection for Light-Coloured Horses

Horses with:

  • Pink skin
  • White markings
  • Light coats

May develop sunburn.

UV-protective rugs help prevent:

  • Skin peeling
  • Painful irritation
  • Long-term skin sensitivity

Especially useful for horses with exposed noses or clipped areas.


6. Fly Masks and Additional Protection

Fly masks protect:

  • Eyes
  • Ears
  • Sensitive facial skin

Choose masks that:

  • Do not press on the eyes
  • Sit securely without slipping
  • Allow clear vision
  • Avoid rubbing at cheeks or poll

Check daily for debris or insects trapped inside.


7. Ensuring Correct Rug Fit in Summer

Poor fit can cause:

  • Shoulder rubs
  • Mane thinning
  • Heat build-up
  • Slipping or twisting

Check that:

  • Chest closures sit flat
  • Shoulder movement is unrestricted
  • Belly flap lies comfortably
  • Neck cover does not press or pull

Fit should be reassessed regularly.


8. Balancing Turnout and Stable Time

Midges are most active at:

  • Dawn
  • Dusk
  • Still, humid evenings

Management options include:

  • Stabling during peak insect times
  • Using fans to reduce insect landing
  • Applying repellents where needed

Layered management is often most effective.


9. Fly Spray vs Fly Rug

Fly sprays:

  • Offer short-term relief
  • Require frequent reapplication
  • May not suit sensitive skin

Fly rugs:

  • Provide continuous barrier protection
  • Reduce chemical exposure
  • Offer consistent coverage

Many horses benefit from a combination approach.


10. Monitoring Skin Under Summer Rugs

Even lightweight rugs require daily checks.

Look for:

  • Dampness or sweating
  • Heat build-up
  • Skin irritation
  • Hair breakage
  • Early rubs

Fly rugs can trap dust — regular washing maintains hygiene.


Signs Your Horse May Be Overheating

Watch for:

  • Excess sweating
  • Rapid breathing
  • Lethargy
  • Reluctance to move
  • Reduced appetite

Remove the rug and reassess if signs appear.


Common Summer Rugging Mistakes

Avoid:

  • Leaving rugs on during heatwaves
  • Ignoring sweating
  • Failing to clean rugs regularly
  • Using rugs when insects are minimal
  • Starting sweet itch protection too late
  • Assuming all horses need rugs

Summer rugging is preventative — not decorative.


The Core Principle

Summer rugs are:

  • Protective barriers
  • Insect management tools
  • UV shields

They are not insulation.

Use them when needed. Remove them when unnecessary. Prioritise airflow, comfort and daily observation.

Successful summer rugging is responsive — not automatic.
