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.

Can humans get botflies?

People rarely acquire this parasite in the US, but those who travel to areas where the botfly is endemic are at risk. Because myiasis is not spread from person to person, the only way to contract it is through exposure to infested flies, ticks, and mosquitoes.
