6 Best Horse Insect Bite Reliefs For Backyard Flocks Old Farmers Swear By

You hear it before you see it: the frantic flutter of wings and the distressed squawks from the coop in the mid-afternoon heat. Biting flies, gnats, and mites are more than just a nuisance; they’re a source of stress and real physical harm for a backyard flock. When your birds are busy scratching bites instead of foraging, their health, happiness, and even egg production can take a hit. Many old-timers know a secret that isn’t found in the poultry aisle—some of the most effective, time-tested remedies are hiding in the equine section of the farm supply store.

Why Horse Products Can Soothe Your Flock’s Skin

It might seem odd to reach for a product designed for a 1,200-pound animal to treat a 6-pound chicken, but the logic is sound. Equine skin is notoriously sensitive, and products formulated for horses are often designed to be gentle yet effective, avoiding harsh chemicals that could cause a reaction. They are built to withstand the rigors of outdoor life, providing durable protection against the same biting insects that plague our flocks.

Furthermore, the economics just make sense for a small farmstead. Horse products typically come in larger, more cost-effective containers. A single tub of ointment can last a flock owner several seasons, offering far better value than the small, specialized poultry products that often come with a premium price tag. These are proven formulas that have been keeping animals comfortable for generations.

Swat Fly Repellent Ointment for Sensitive Areas

Swat is a staple in almost every horse barn, and for good reason. This thick, pink (or clear) ointment acts as both a physical barrier and a chemical repellent. It’s specifically designed to stick to sensitive, hard-to-protect areas where flies love to congregate.

For chickens, this makes it ideal for dabbing around the vent, comb, and wattles—places that are prime targets for biting black flies and gnats. A tiny amount creates a no-fly zone that lasts for hours. The ointment is greasy and tenacious, which is its greatest strength and its main drawback.

Be warned: a little goes a long way. If you apply too much, it will mat the feathers and attract dirt, creating a bigger mess. Use just a thin film on the skin itself, not slathered on the feathers. It’s a targeted tool for problem spots, not a full-body solution.

Corona Ointment: A Classic Lanolin-Based Salve

If you see a beat-up yellow tin in a farmer’s toolbox, there’s a good chance it’s Corona. This isn’t a repellent; it’s a thick, lanolin-based healing salve that has been around for over a century. Its primary job is to soothe irritated skin and create a barrier that promotes healing underneath.

Think of Corona as the ultimate multipurpose skin conditioner for your flock. It’s brilliant for soothing pecked combs, moisturizing dry legs, or protecting a bare patch of skin from sun and insects while the feathers grow back. Many farmers also swear by it for treating scaly leg mites; the thick ointment suffocates the mites while softening the damaged scales.

Because it’s so gentle, it’s one of the safest options for use on any part of the bird. Like Swat, it’s greasy, so apply it sparingly. It’s the go-to remedy for healing existing damage, rather than preventing new bites.

Vetericyn Plus Hydrogel for Non-Toxic Healing

For those wary of traditional, chemical-based treatments, Vetericyn Plus Hydrogel is a modern marvel. It’s not a repellent, but a first-aid treatment for cleaning and healing wounds, including insect bites, pecking sores, and scratches. Its active ingredient, hypochlorous acid, is a non-toxic substance that mimics the body’s own immune system to fight infection.

The hydrogel formulation is key here. Unlike a liquid spray that runs off, the gel clings to the application site, keeping the wound clean and moist to encourage healing. It doesn’t sting or burn, so the birds tolerate it well. Best of all, it’s completely safe if ingested, which is a major relief when you have birds that preen themselves and peck at each other.

This is your first line of defense when a bite becomes an open sore. It won’t keep the next fly from landing, but it will ensure the existing damage heals quickly and cleanly without introducing harsh chemicals to your flock’s system. It’s a must-have for any chicken first-aid kit.

Absorbine UltraShield Green: A Natural Repellent

When you need to treat the whole bird or the coop area without resorting to heavy chemicals, Absorbine UltraShield Green is a fantastic choice. This is a natural, essential oil-based fly spray that uses ingredients like geraniol, cedar, and lemongrass oil to repel pests. It has a pleasant, botanical scent that’s a welcome change from the chemical smell of other repellents.

This product is best used as a preventative measure. You can lightly mist it over your flock’s backs and undersides (avoiding their faces) before letting them out on a buggy day. It’s also excellent for spraying around coop entrances, windows, and roosts to deter flies from settling in.

The main tradeoff with any natural repellent is longevity. You will need to apply it more frequently than a synthetic, chemical-based spray. Its effectiveness relies on consistent use. But for the farmer who prioritizes a natural approach, that extra effort is a small price to pay for peace of mind.

Shapley’s M-T-G: A Potent Sulfur Treatment

Shapley’s M-T-G (which stands for Mane-Tail-Groom) is the heavy artillery of skin treatments. This sulfur-and-oil-based product is legendary in the horse world for clearing up tough skin conditions, and it can be a miracle worker for chickens—if used with caution. It has a very strong, distinct smell of bacon and sulfur that you won’t soon forget.

M-T-G is not for simple fly bites. This is what you reach for when dealing with a stubborn case of scaly leg mites, depluming mites, or fungal issues that cause feather loss and intense irritation. The sulfur combats fungus and kills mites, while the oil base soothes the skin and suffocates any remaining pests.

This is a powerful treatment, not a casual remedy. Apply it sparingly with a gloved hand or small brush directly to the affected skin, not the feathers. Use it in a well-ventilated area, and be aware that the oily base can make birds more susceptible to chilling in cold weather. It works wonders, but it demands respect.

DIY Herbal Salve: A Homemade Farmstead Remedy

For the truly self-sufficient farmer, a homemade herbal salve offers complete control over every ingredient. Creating your own remedy is straightforward and connects you more deeply with the process of caring for your animals. The basic formula involves just three components: a carrier oil, beeswax, and herbs.

Start by infusing a carrier oil like olive or coconut oil with dried, skin-soothing herbs.

• Calendula is anti-inflammatory and promotes healing.
• Plantain (the common yard "weed") is excellent for drawing out the sting from bites.
• Comfrey helps with skin cell regeneration but should be used on clean wounds, not deep punctures.

After straining the herbs, gently heat the infused oil with a small amount of beeswax until it melts. Pour it into a tin and let it cool. You can add a few drops of pest-repelling essential oils like cedarwood or lavender for extra benefit. This salve can be used just like Corona for general skin soothing and protection.

A Farmer’s Guide to Safe Flock Application

Using any product, whether it’s from a store or your own kitchen, requires a dose of common sense. The goal is to help your birds, not create new problems. Following a few simple rules will ensure you get the benefits without the risks.

First, always test a small, inconspicuous patch of skin before applying a new product widely. Dab a small amount under a wing and wait 24 hours to check for any redness or irritation. This simple step can prevent a flock-wide disaster.

Apply ointments and salves at night when the birds are on their roost. This gives the product time to absorb without the sun beating down on it and, more importantly, prevents other curious chickens from pecking at the shiny, treated spot. Remember, chickens are drawn to anything that looks different.

Finally, less is always more. A thin layer applied directly to the skin is far more effective than a thick glob caked onto the feathers. Matted, greasy feathers can interfere with a bird’s ability to regulate its body temperature. Part the feathers, treat the skin, and trust that the product will do its job.

Ultimately, the best insect bite relief is the one that fits your philosophy and solves the specific problem your flock is facing. Whether you choose a time-tested classic, a modern non-toxic gel, or your own homemade remedy, the key is careful observation and consistent application. A well-stocked medicine cabinet with a few of these equine staples will have you prepared for whatever the bug season throws your way.
