Myiasis caused by endemic Cuterebra species in the US and Canada is rare, with approximately 60 cases reported in the past 70 years [1]. Most Cuterebra infections manifest as furuncular myiasis with second instar larvae [1] or respiratory infection from mature third-instar larvae [2].

How long can a botfly live in a human?
The insect lays its eggs on animals like flies or mosquitoes. Those insects become hosts, carrying the human botfly eggs to human skin — the warmth of which hatches the eggs into larvae, researchers said. The larvae then burrow into the human skin, where they live for 27 to 128 days, causing itching in their hosts.
How does a person get a botfly?
To reproduce, female botflies lay eggs on blood-sucking arthropods such as mosquitoes or ticks. The infested arthropods deposit larvae from the eggs when they bite a human or other mammal.
