Best Fly Spray for Horses UK: How to Choose the Right Protection for Your Horse
Share
As the weather warms up, flies, midges and other biting insects quickly become one of the biggest frustrations for horse owners. Not only can flies be annoying, but they can also cause discomfort, stress and distraction for horses both in the field and when ridden.
With so many horse fly sprays available, choosing the right one can be difficult. Some owners prefer natural fly repellents, while others need stronger, longer-lasting protection during peak fly season.
In this guide, we'll look at the different types of horse fly spray available and how to choose the best option for your horse.
Why Do Horses Need Fly Spray?
Flies are more than just a nuisance. Constant irritation can lead to:
- Tail swishing & stamping
- Head shaking
- Rubbing & skin irritation
- Loss of concentration when riding
- Stress & discomfort in the field
Some horses are naturally more sensitive to flies than others, particularly those with sweet itch or sensitive skin.
Using a quality fly spray as part of your horse's summer management routine can help keep them comfortable and happier throughout the warmer months.
Natural vs Chemical Fly Sprays
One of the biggest decisions horse owners face is whether to choose a natural fly spray or a stronger chemical-based product.
Neither option is automatically better than the other. The right choice depends on your horse, their environment and how severe the fly problem is.
Natural Fly Sprays
Natural fly sprays use plant-based ingredients to help repel insects. Many owners choose them for horses with sensitive skin or for everyday use.
Benefits of natural fly sprays include:
- Gentle on sensitive horses
- Pleasant scent
- Often suitable for frequent use
- Made using plant-based ingredients
However, natural products may require more frequent application, particularly during hot weather or periods of heavy fly activity.
Stronger Fly Sprays
Some fly sprays contain active ingredients designed to provide longer-lasting protection.
These products are often chosen for:
- Horses that are particularly attractive to flies
- Long periods of turnout
- Riding & competitions
- Areas with severe fly & midge problems
Always read and follow the manufacturer's instructions carefully when using stronger fly repellents.
How Do Natural Fly Sprays Work?
Natural fly sprays don't usually kill insects. Instead, they help make horses less attractive to flies by masking scents and creating an environment insects prefer to avoid.
Many natural horse fly sprays contain ingredients such as:
Citronella
Citronella is one of the most popular ingredients found in natural fly sprays. Derived from lemongrass, it has a distinctive scent that helps mask the smells that attract flies and midges.
Products such as NAF Off Citronella Spray are popular choices for horse owners looking for a natural alternative.
Eucalyptus Oil
Eucalyptus oil is commonly used in fly repellents due to its fresh scent and insect-deterring properties.
It is particularly popular during the summer months when fly activity is at its highest.
Tea Tree Oil
Tea tree oil is often included in grooming and fly repellent products. Alongside its distinctive aroma, it is frequently used in products aimed at supporting healthy skin.
Lavender Oil
Lavender is another common ingredient found in natural fly sprays. Its pleasant scent makes products enjoyable to use while helping discourage insects from settling on horses.
Neem Oil
Neem oil has become increasingly popular in natural fly repellents. It has been used for many years in insect-repelling products and is often included in formulations designed to reduce fly irritation.
Because natural ingredients evaporate more quickly than stronger chemical formulations, natural sprays often need reapplying more frequently throughout the day.
Best Natural Fly Sprays for Horses
Horse owners looking for a natural approach often choose products containing citronella and essential oils.
Popular options include:
These products are ideal for everyday use and for horses that don't require heavy-duty fly protection.
Best Long-Lasting Fly Sprays
For horses that spend long periods turned out or are badly affected by flies, a stronger formula may be more effective.
Popular choices among horse owners include:
These products are often chosen when flies are particularly persistent or during peak summer conditions.
Tips to Make Fly Spray More Effective
Even the best fly spray works better when combined with good management practices.
Keep Fields Clean
Regularly removing droppings can help reduce fly breeding areas.
Use Fly Rugs and Fly Masks
Fly rugs and masks provide an additional layer of protection, particularly for horses that are highly sensitive to insects.
Apply Correctly
Always follow the manufacturer's instructions and ensure the product is applied evenly.
For sensitive areas such as the face, spray onto a cloth first before carefully wiping around the area.
Reapply When Needed
Hot weather, rain and sweating can reduce effectiveness, so regular reapplication may be necessary.
Which Fly Spray Is Right for Your Horse?
- For sensitive horses: Natural citronella-based products
- For everyday turnout: Standard fly sprays with regular reapplication
- For severe fly problems: Longer-lasting formulations such as Flygard or NAF Off Extra Effect
- For maximum protection: Combine fly spray with a fly mask and fly rug
Final Thoughts
The best fly spray for your horse will depend on their individual needs, skin sensitivity and the severity of the fly problem.
For everyday use, natural products containing citronella and essential oils can be an excellent choice. For horses that require more robust protection, stronger formulas may provide longer-lasting results.
Whichever product you choose, combining fly spray with sensible stable and field management can help keep your horse comfortable and protected throughout the fly season.
