Dear GOD,
Thank you for letting me be born in the USA! Here we dont worry about things like botflies. In this video, a man in Panama was bitten by a mosquito that had botfly eggs.
The eggs got into his skin and began to eat him from the inside out. By using vaseline or camphorated grease, the botfly was starved out of air and came closer to the surface where... well you'll see....
WARNING! NOT FOR THE SQUEAMISH OR THOSE THAT EASILY GET NIGHTMARES!!!!
