How do you get a Botfly infection

By Mia Walsh |

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.

One type of botfly latches onto mosquitoes mid-flight, attaching their eggs to the mosquitoes’ stomachs.
