Before You Buy
Key Buying Factors
01
Active Ingredients
Look for pyrethrins or permethrin for effective repellency, but be cautious if your Quarter Horse has sensitive skin. Natural options like essential oils are gentler but may require more frequent application.
02
Sweat and Water Resistance
Quarter Horses sweat heavily during exercise, so choose a spray that resists sweat and water to maintain protection. This is crucial for horses that are worked regularly or turned out in wet conditions.
03
Application Form
Consider whether your Quarter Horse tolerates sprays, wipes, or spot-on treatments. For horses that dislike spray bottles, wipes or spot-on products may be easier to apply and less stressful.
04
Skin Sensitivity
Quarter Horses can have sensitive skin, especially if they have thin coats or are prone to allergies. Opt for sprays with added conditioners like aloe, lanolin, or natural oils to soothe and protect the skin.
05
Duration of Protection
Longer-lasting formulas reduce the frequency of application, which is beneficial for busy owners. Sprays that offer up to 14 days of protection are ideal, but note that heavy sweating may shorten effectiveness.
Pro tip
Our team suggests applying fly spray to a cloth first when treating the face to avoid getting it in your Quarter Horse's eyes or nostrils. For optimal protection, reapply after heavy sweating or rain, especially if using a natural formula.
Frequently asked questions
Can I use dog or human fly spray on my Quarter Horse?
No, you should only use products specifically formulated for horses. Dog or human fly sprays may contain ingredients that are toxic to horses or cause skin irritation. Always choose equine-specific products to ensure safety and effectiveness.
How often should I apply fly spray to my Quarter Horse?
The frequency depends on the product and your horse's activity level. Most chemical sprays last 3 to 14 days, but heavy sweating or rain can reduce effectiveness. Natural sprays may need daily reapplication. Always follow the label instructions.
Is it safe to use fly spray on a Quarter Horse with sensitive skin?
Yes, but choose a spray labeled for sensitive skin or with natural ingredients. Look for conditioners like aloe vera or lanolin. Test a small area first and monitor for any reaction. If irritation occurs, discontinue use and consult a veterinarian.
Can I make my own fly spray for my Quarter Horse?
Homemade fly sprays using essential oils like citronella, eucalyptus, or lavender can be effective for some horses. However, they are not as long-lasting as commercial products and may require frequent reapplication. Ensure the oils are diluted properly and never use tea tree oil as it can be toxic to horses.
What is the best way to apply fly spray to a Quarter Horse?
Apply in a well-ventilated area, avoiding the eyes and mouth. Use a spray bottle with a fine mist and hold it 6 to 8 inches from the coat. For the face, spray on a cloth and wipe gently. Reapply as needed, especially after sweating or rain.
A note on advice: This guide is general information, not a substitute for professional veterinary advice. Talk to your vet before changing your dog's diet or care routine, especially if your dog has allergies, kidney disease, pancreatitis, obesity, heart disease or any other medical condition.
