The larva is also three-quarters of an inch long with a narrow hooked end and a broad, rounded body. The strategic use of fans helps decrease fly populations in horse stalls and keeping the manure pile as far away and downwind of the barn as possible will also help. This approach is based on concepts and strategies developed more than 40 years ago when large strongyles were the most common and damaging internal parasite in horses. The larvae stay specifically in the stomach, where they attach to the A veterinarian can diagnose bots in a horse by a microscopic examination of its feces. The effects of internal parasites are more evident in young and malnourished horses. In the warm summer months adult bot flies are a common sight around horses.
The horse then licks or bites the spot where the eggs are and subsequently ingests them. A grooming tool called a bot knife allows the person grooming the horse to easily and safely scrape the side of the horse’s skin to remove the eggs without injuring the horse.

If still untreated parasites can cause pneumonia, emaciation, severe and debilitating diarrhoea, permanent organ damage and colic, it is possible that some of these could lead to death.In terms of equine health and management priorities, creating an effective parasite control program is probably second only to supplying the horse with clean water and high quality feed and roughage. The botfly as an adult insect does not actually bite or cause direct pain to the horse, but begins by laying eggs on the outer body of the horse – on the skin of the inner legs and knees, around the chin and nose, and on the belly.

With daily use during botfly season, this tool can drastically reduce the number of larvae that are ingested by the horse.
Eggs are laid on exterior of horse in the spring to fall months and left to migrate to the stomach 2. The larvae of the botfly is referred to as a bot, and a horse that is infested with botfly larvae is said to have bots. They live in stored re…
