When it comes to keeping insects off, nature actually designed the horse fairly well.Long manes with a forelock over the eyes and a tail that can swish and reach the shoulder, gives the horse good coverage. However, since people have begun controlling genetics, not nature, recent breeds are not as effective at insect control as the older, thick-skinned breeds.
Here's an obvious example: my two wild horses graze peacefully while my thoroughbred shakes his head, trying to keep it near my mustangs' tails to avoid annoying insects.
Watching to see which horses have flies and where they land can give you lots of information about your horse. Insects in general are attracted to energy fields considered "out of balance" or even "Noxious" (harmful) to humans and other animals. Flies will be more attracted to people and horses with unbalanced energy. When a friend stayed with me for a couple of months last summer with her event horses, we noticed that one horse was covered with flies. That was unusual for my barn. On the right side of his neck, between the third and fourth cervical vertebrae, there was a patch of flies the size of a silver dollar. They created a bald spot on the horse. Observing this, we checked him and found him to be "out" in the third and fourth cervical vertebrae. After working on his neck to re-balance his energy flow, the flies quit bothering his neck.
Generally speaking, if you understand insect ecology, use biological control, and have a balanced and healthy horse, little or no fly sprays should be needed. However, if you feel you must use fly sprays, or want your horse to smell good, natural essential oil formulations offer a variety of wonderful insect controls. Bear in mind, no matter which formulas you use, insects will adapt to them in a relatively short time, so you need to rotate your sprays in a random order to not set a pattern that the hardy insects will be able to figure out and adapt to.
Your fly sprays can be sprayed as a liquid, or made into a lotion. I find that rubbing on a lotion lasts longer. One that I found that works wonderfully was developed to deal with the jungles of West Palm Beach, Florida, appropriately named "Junglepoo." Another option is to rub apple cider vinegar into the hooves and legs, or feed your horse vinegar or garlic (Equilite's Garl+C) during the fly season--his sweat will act as a natural repellent.
The following essential oils are known to be unpleasant to insects. They should be mixed with water or a lotion, or blended with oils so that they are diluted in strength. Straight essential oils are too concentrated to be used directly on an animal and may cause toxic side effects. I recommend not mixing more than two or three oils together because this can cancel out the properties of the oil.
When mixing a lotion or wipe-on insect repellent, use a natural aloe vera base lotion diluted with 40-50% water or Witch Hazel. The Witch Hazel helps to keep the skin from clogging. If making a spray, use one-third lotion, one-third witch hazel, and one-third water, with one-quarter to one-half ounce of essential oils, depending upon the oil. This can make 16-32 ounces of spray, depending upon how strong you need to make your repellent.
Here's a list of insect repellent oils and recipe's for you to try. Most of the essential oils can be purchased in you local health food store.
