The Human Botfly
The Botfly is an insect that in the larval stage lives in animals and sometimes in humans. Human Bot flies are found in Central and South America, particular in the sub-tropical and tropical regions.
The human botfly does not bite or lay its eggs on people, but attach its eggs to smaller flies or mosquitoes by gluing its eggs to their bodies. When the mosquito bites a person, the eggs are released onto a human and then because of the body heat, the eggs hatch into larvae and the larvae uses the mosquito bite area as the entry point or borrow themselves into the skin.
Once inside the skin, the larvae then begin feeding on the skin tissue. Tiny hooks secures the larvae in place, and it secrets an antibiotic into its burrow, which staves off competing bacteria. A boil-like lesion develops on the skin a tiny hole is present, so the larvae can breathe.
If not removed the Botfly larvae will develop inside the skin for about 6-8 weeks. The then drop out to the ground, where they pupate. Adult botflies emerge from the pupas in about 20 days, and the cycle starts all over again.
How to Remove a Botfly
To remove a botfly maggot, you have to cut off the air supply of the larvae by sealing off the air hole found in the surrounding blister.
One way to do that is cover with Petroleum Jelly, Vaseline or Duct Tape to cut off the air supply. This forces the grub to expose itself, so it can be pulled or squeezed out.
Another suggested solution to remove the larva is use a venom extractor syringe. These syringes are common in some first-aid kits to deal with snakebites.

If bitten by a mosquito or a small fly that you think could be a carrier of the bot fly egg apply alcohol immediately to the area where you think you have been bitten. The alcohol will kill the larvae.
