Horse Fly Control

Horse flies can be a nuisance for both horses and their owners, causing discomfort, irritation and potentially transmitting diseases. With the right repellent strategies, you can effectively protect your equine friends and ensure their well-being.

Horse flies, also known as gadflies, are large, robust flies known for their painful bites. They are commonly found in rural areas, near bodies of water and in regions with livestock. Female horse flies require blood meals to reproduce, making them persistent biters and potential carriers of diseases.

Horsefly bites can lead to skin irritation, allergic reactions and secondary infections. In severe cases, excessive biting can cause stress and weight loss in horses. Additionally, some horsefly species are vectors for diseases such as equine infectious anaemia and tularemia.

When selecting horsefly repellent products, consider factors such as effectiveness, safety and ease of application. Look for repellents specifically formulated for use on horses, and follow the manufacturer's instructions for proper application and reapplication intervals. Additionally, consult with your veterinarian for recommendations tailored to your horse's individual needs and health status.

Frequently Asked Questions (FAQs)

How often should I apply topical repellents to my horses to effectively deter horse flies?

Topical repellents should typically be applied to horses according to the manufacturer's instructions, which often recommend reapplication every few days or after exposure to water (such as rain or swimming). 

However, factors such as the concentration of active ingredients, environmental conditions and horse activity level may influence the duration of effectiveness.

It's advisable to monitor your horse for signs of fly irritation and reapply repellents as needed for continuous protection.

Are there any specific environmental factors that contribute to increased horsefly populations, and how can I mitigate them? 

Stagnant water sources such as ponds, puddles or water troughs, decaying organic matter like manure piles, compost heaps and dense vegetation. Additionally, warm and humid climates are conducive to fly breeding. 

To mitigate these factors, regularly inspect and clean water sources, properly dispose of manure, maintain clean surroundings, and consider using larvicides or biological controls to target horse fly larvae in breeding areas.
