What happens if a bot fly is not removed?

How do humans get botfly?

One type of botfly latches onto mosquitoes mid-flight, attaching their eggs to the mosquitoes’ stomachs. Then, when a mosquito lands on a human’s skin, the eggs burrow into the tiny wound left by the mosquito bite. Eventually, these eggs turn into larvae and will dig their way out from underneath the skin.
