Nasal bots are the larvae form of bot flies, Cephenemyia spp. Adult female flies deposit small larvae on the skin of the nose and mouth of white-tailed deer. Larvae develop and migrate into the nasal passages where they develop further. Eventually fully developed larvae will exit the deer (possibly through a sneeze) and pupate in the ground to complete their life cycle. Bot larval infections appear to be relatively common in white-tailed deer in Florida and even in large quantities do not cause harm to deer. Deer with bot infestations are no harm to humans.
FWC Facts:The mean breeding period (rut) of white-tailed deer in Florida can vary as much as seven months from one part of the state to another.
