Bot Eggs

Another interesting life cycle.  Adult bot flies deposit their eggs on horses’ forelegs and shoulders, or around the horse’s jaws and lips.  When the larvae hatch, they move into the mouth where they burrow into the tissues of the gums and the tongue to develop further.

Eventually, they migrate into the stomach and intestines where they live for up to 12 months before passing out of the horse and develop into adult bot flies in the soil.  These parasites are not seen during routine fecal analysis and are considered low risk from a animal health perspective.

We recommend the use of a simple bot knife to scrape off the the white looking eggs as soon as they are seen on your horse taking care not to scrape on to gazing pasture!
