Not all botfly attacks humans. It doesn’t transmit any diseases. It should also be noted that humans are frequently affected by the Dermatobia hominis species of the botfly, though other kinds of fly species cause myiasis in the human body. Their lifecycles vary greatly according to species, but the larvae of all species are internal parasites of mammals. Botflies, or Cuterebra, are larvae that form in the tissues of animal hosts. the infective cuterebra larvae in an infested dog is 30 days (80%), 14 days (15%) and 60 days (5%). A botfly, also written bot fly, bott fly or bot-fly in various combinations, is any fly in the family Oestridae.

Cuterebra larvae develop within the tissues of certain animal hosts, and during this phase of their life cycle, they are commonly referred to as 'warbles'. Bot Fly larvae act as internal parasites of mammals.
