My Buying Guides on Endure Fly Spray Gallon
When I first started looking for an effective fly spray for my horses, the Endure Fly Spray Gallon quickly caught my attention. After using it for a while, I wanted to share my experience and helpful tips to guide you through the buying process. Here’s what I found important to consider:
Why I Chose Endure Fly Spray Gallon
For me, the key was finding a product that not only repelled flies but also lasted long without constant reapplication. Endure Fly Spray offers a strong, long-lasting formula that protects against flies, mosquitoes, gnats, and other biting insects. Plus, buying it in a gallon size means I get plenty of product to cover multiple horses and last through the season.
Effectiveness and Ingredients
I always check the ingredients to ensure safety for my animals. Endure uses permethrin, which is a proven insecticide that effectively repels and kills flies. It’s important to follow the instructions carefully to avoid overuse, but I appreciated how it kept pests away without irritating my horses’ skin.
Size and Value
Buying the gallon size was a no-brainer for me because it offers the best value. Smaller bottles run out quickly, and I found myself constantly repurchasing. With the gallon, I can refill smaller spray bottles and keep a steady supply on hand. It’s cost-effective and convenient.
Application Tips I Learned
From my experience, spraying directly on the horse’s coat, legs, and around the face (avoiding eyes and mouth) works best. I also spray tack and stall areas for extra protection. Applying it in the morning or evening when flies are most active helped maximize its effectiveness.
What to Watch Out For
I noticed that some horses can be sensitive to strong insecticides, so I recommend doing a small patch test first. Also, make sure to store the gallon in a cool, dry place out of direct sunlight to maintain its potency. Lastly, always wear gloves when handling the concentrate to protect your skin.
Where to Buy and Pricing
I found the Endure Fly Spray Gallon available at most equine supply stores and online retailers. Prices vary, but buying online often gives better deals or bulk discounts. Keep an eye out for seasonal sales, especially before fly season starts.
Final Thoughts
Overall, my experience with the Endure Fly Spray Gallon has been very positive. It’s a reliable, economical option that keeps my horses comfortable and fly-free. If you’re looking for a heavy-duty fly spray that lasts and covers a lot of ground, I’d definitely recommend giving this one a try!
