Bots are a type of intestinal parasites that are larvae of the botfly, Gasterophilus. Female botflies lay their eggs by attaching them to the hairs of the horse.

Botflies, also known as warble flies, heel flies, and gadflies, are a family of flies technically known as the Oestridae. Their larvae are internal parasites of mammals, some species growing in the host's flesh and others within the gut. Dermatobia hominis is the only species of botfly known to parasitize humans routinely, though other species of flies cause myiasis in humans.
