Remove Bot Fly Eggs
 
SUMMARY
Bot flies lay sticky pale yellow eggs on horse's hair, usually on the forearms belly and chest. Adult bot flies lay their eggs on horses, the flies do this instinctively.

A basic part of the bot's life cycle requires that the horse bite at and swallow the eggs. The eggs hatch into larvae that over-winter attached to the lining of the horse's stomach.

Bots are not thought to be very harmful to horses unless they infest a horse in high numbers. However, bot eggs that pepper the hair coat is aesthetically undesirable.

In late fall and winter moxidectin and ivermectin dewormer treatments kill bot larvae in the stomach, an important means of control. However, it is preferable to remove bot eggs before they are ingested, to reduce the number of larvae in the stomach.
