FAQ

What is the best fly spray for horses?

The best fly spray for horses depends on your horse's environment, workload, and insect pressure. The UltraShield® line from Absorbine® offers a variety of proven fly control solutions designed to repel and kill flies, mosquitoes, ticks, gnats, and other biting insects as listed on the label, helping keep horses comfortable throughout fly season.

How do I choose the right UltraShield® fly spray for my horse?

UltraShield® offers several fly control options to meet different needs. Some formulas provide everyday fly protection, while others offer weather-resistant performance, natural ingredients, or extended insect control. Consider your horse's lifestyle, climate, and exposure to insects and then refer to each formula’s labels when selecting the best fly spray.

How often should I apply fly spray to my horse?

Application frequency varies depending on the product, weather conditions, and insect activity. During peak fly season, horses may benefit from regular reapplication to maintain protection. Always follow the label directions on your chosen UltraShield® product for best results.

Does UltraShield® help protect horses from mosquitoes and ticks?

Yes. Many UltraShield® formulas are designed to repel and kill multiple pests, including mosquitoes and ticks, in addition to flies. Refer to labels to see targeted insects. Broad-spectrum insect protection helps support your horse's comfort during turnout, riding, training, and other outdoor activities.

Why is fly control important for horses?

Flies and other biting insects can cause irritation, stress, discomfort and even diseases that may affect a horse's well-being and performance. An effective fly control program using a trusted horse fly spray can help reduce insect annoyance and make time spent outdoors more enjoyable for your horse.
