What causes bot flies in humans?
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. A botfly larva enters the host's skin through the bite wound or a hair follicle and burrows to subcutaneous tissue.
