Horse bots, also known as Gasterophilus flies, are honey bee-sized flies that fly around horses, laying their eggs on a horse’s coat. Though they do not pest or sting, they quickly dart around horses, which can cause horses to injure themselves trying to flee from them.
There are three types of horse bots: the common bot (Gasterophilus intestinalis), the throat bot (G. nasalis) and lastly the nose bot (G. haemorrhoidalis). They are considered a type of parasite and are common all throughout the world.
Bot flies are active during the warm months of the year and generally don’t disappear until the first frost. They generally come in abundance, causing annoyance to your horse.
What Do Bots Do to Horses?
Bot flies have three life stages that begin with laying their eggs on a horse. They generally lay their eggs on horses anytime from late summer to early fall.
The common bot generally lays its eggs on the legs of horses, along with their flanks and manes. Throat bots will attach their eggs to the long hairs underneath the jaw of horses. Nose bots will lay their eggs on the lower and upper lips of a horse.
The eggs of the bot fly are small, often ranging in color from yellow to gray. After the eggs are attached to the hair, horses will generally bite or lick them. The eggs generally hatch after a two to five day incubation period and are generally stimulated by the warmth and moisture of a horse’s tongue.
At this point, the larvae either make their way into a horse’s mouth or are taken in unknowingly from a horse biting or liking itself. From there, they will spend about three weeks in the soft tissue of the lips, gums, or tongue. After that, they make their way to the stomach or small intestine of the horse where they use their sharp mouth hooks to attach to the lining of the organ.
They will spend around seven months in the stomach or small intestine before leaving the horse via manure. After that, they enter the soil and pupate, emerging as adults in anywhere from two weeks to two months.
In most cases, bots will generally not cause any harm to horses. However, while inside the horse, bots can cause damage the lining of the stomach or small intestine, interfere with digestion, and cause other gastrointestinal disorders. In severe infestations, they can cause colic, weight loss, ulcers, poor appetite, and abdominal pain.
Signs Of Bots In Horses – What Do Bots Do to Horses?
The first signs of bots you will see in horses are the eggs on their hair. Though they are relatively small, they are generally still noticeable, especially when the eggs are yellow. The eggs are normally found in clusters in different spots on the horse.
You may notice your horse excessively biting or liking itself when the larvae have just hatched. In some cases, a horse may rub its face or bite strange objects to relieve the irritation of the larvae in the mouth. If a horse ingests the larvae of bot flies, there is a good chance that you will not notice.
In more serious cases, a horse may colic, have a loss of appetite or show signs of other digestion problems. In addition, they may develop ulcers as a result of the larvae.
