Natural Fly Control for Horses

Flies are a persistent problem for horses during the warmer months. They cause irritation, spread diseases, and lead to skin infections. While chemical fly sprays and repellents are commonly used for fly control, many horse owners are seeking natural alternatives that are safer for their horses and the environment. Various natural fly control methods, including environmental management, herbal repellents, and physical barriers help keep your horse comfortable and fly-free.

1. Managing the Environment for Fly Prevention

Keeping the Stable and Pasture Clean

One of the most effective ways to control flies naturally is through proper management of your horse’s living environment. Flies are attracted to manure, rotting vegetation, and standing water, where they breed and lay eggs. By reducing these attractants, you can significantly reduce the fly population around your horse. Regularly cleaning stalls and removing manure from paddocks or pastures helps minimize fly breeding grounds. In addition to cleaning stalls and paddocks, ensure that feed and water sources are kept clean and covered to prevent contamination. Flies are often attracted to spilled grain and dirty water buckets, so maintaining a clean environment is key to reducing their presence. Composting manure away from the stable and using fly traps around the perimeter of your horse’s living area can also help reduce fly numbers naturally.

Proper drainage in pastures and paddocks is another important aspect of fly prevention. Stagnant water creates the perfect breeding environment for flies and mosquitoes. Ensuring that water troughs, puddles, and low-lying areas are regularly cleaned or drained prevents flies from laying eggs and multiplying.

Introducing Fly Predators

Fly predators are tiny parasitic insects that can be introduced into your horse’s environment to naturally control the fly population. These beneficial insects, such as certain species of wasps, lay their eggs in fly pupae, preventing the flies from maturing and hatching. Fly predators are harmless to horses and humans but are effective at reducing fly numbers without the use of chemicals. Fly predators are easy to use and can be purchased from equine supply stores or online. They should be released in areas where flies are most likely to breed, such as near manure piles or compost bins. By introducing fly predators into your horse’s living space early in the season, you can prevent flies from becoming a major problem. Over time, the population of flies will decrease, leading to a more comfortable environment for your horse.

2. Herbal and Natural Fly Repellents

Essential Oils for Fly Control

Essential oils have been used for centuries to repel insects, and they can be a natural and effective way to keep flies away from your horse. Many essential oils, such as citronella, eucalyptus, lavender, peppermint, and tea tree oil, have insect-repellent properties and can be used to create homemade fly sprays. These oils not only help repel flies but also provide a pleasant scent for your horse. To make a natural fly spray, combine water, a small amount of apple cider vinegar, and a few drops of essential oils in a spray bottle. Shake well and apply the spray to your horse’s coat before turnout or riding. Be sure to test the spray on a small patch of skin first to ensure your horse doesn’t have any sensitivity to the oils. Natural fly sprays made with essential oils are a safer alternative to chemical-based products and can be applied as often as needed. In addition to homemade fly sprays, you can apply essential oils directly to your horse’s skin by diluting them with a carrier oil, such as coconut or olive oil. Applying the oil mixture around sensitive areas like the ears, neck, and legs helps keep flies from bothering your horse. Essential oils are an excellent natural solution for keeping flies at bay without the use of harsh chemicals.

Apple Cider Vinegar and Herbal Supplements

Apple cider vinegar is another natural remedy that can help repel flies when added to your horse’s diet or used as a topical spray. When given as a supplement, apple cider vinegar alters the horse’s sweat composition, making it less attractive to flies. A small amount of apple cider vinegar can be added to your horse’s feed or water to achieve this effect. As a topical treatment, apple cider vinegar can be mixed with water and sprayed directly onto your horse’s coat to deter flies. Some horse owners also add garlic supplements to their horse’s diet, as garlic is believed to help repel flies by altering the horse’s natural scent. Herbal supplements, such as brewers yeast and flaxseed, are also believed to help improve the condition of the horse’s skin and coat, making them less attractive to flies. While the effectiveness of these supplements may vary, they are a natural option worth exploring as part of your fly control strategy.

3. Physical Barriers: Protecting Your Horse Naturally

Fly Masks, Sheets, and Boots

Fly masks and sheets are particularly useful for horses that are sensitive to flies or suffer from conditions like sweet itch, a skin condition caused by an allergic reaction to fly bites. These barriers provide continuous protection from biting flies and other pests and can be used in conjunction with natural repellents or sprays. Many fly masks and sheets also have UV protection, which helps shield your horse from the sun’s harmful rays.

When using physical barriers, ensure that they fit your horse properly and are comfortable for extended wear. Fly masks should be checked daily for any signs of wear or irritation and removed regularly to allow the horse’s face to be cleaned. Properly fitted fly sheets and boots will keep your horse comfortable and fly-free.

Fans and Fly Traps

Another simple but effective way to control flies around your horse’s environment is by using fans and fly traps. Flies are weak fliers, so installing fans in stables or barns helps keep them away by creating a constant breeze. Fans can also help keep your horse cool during hot weather, making them a dual-purpose solution for fly control.

Fly traps, such as sticky traps or bait traps, can be placed around the barn, stable, or paddock to capture flies before they become a nuisance. These traps are easy to set up and work well alongside other natural fly control methods. By placing traps in key areas, such as near manure piles or feed bins, you can significantly reduce the fly population in your horse’s environment.

Planting Insect-repelling Plants

Catnip is great to plant in pots, it is a member of the mint family and produces an oil called nepetalactone which attracts cats but deters pests. Basil is another herb that can be planted around stables to repel both flies and mosquitoes. Lavender deters flies and fleas, and lemon thyme is great as it contains citronella oil, another natural insect repellent. Rosemary and Lavender hedges are also commonly used to discourages flies and other insects. The good news about all of these plants is that they are safe for horses, even to consume in small quantities (if they should happen to take a bite).
