Botflies (Gasterophilus spp) are parasitic flies that affect the horse’s digestive tract and can cause negative health consequences.
Botflies lay eggs on the horse’s coat in the summer. Some of these eggs, known as horse bots, are ingested as the horse licks and grooms itself.
The bot eggs hatch and the larvae develop in the horse’s mouth before migrating to the stomach where they attach to the gastric mucosa.
Once mature, they detach and are passed through the manure. They pupate into flies, and the cycle repeats with new botflies seeking out horses to host their eggs.
Prevention and treatment of bot invasion are essential to keeping your horse healthy. If you suspect that your horse is affected by botflies, consult with your veterinarian for a diagnosis and treatment options.
