Apparently this is nothing uncommon, at least in Central America. Check out the first vid of some botfly maggots being removed from a guy's back - and a second vid (if the first one wasn't enough grossness for you), of one maggot being pulled from a guy's head that's been growing in there for a month! ....
Fast Fact: The easiest and most effective way to remove botfly larvae is to apply petroleum jelly over the location, which prevents air from reaching the larva, suffocating it. It can then be removed with tweezers safely after a day. White glue mixed with pyrethrin or other safe insecticides and applied to the spot of swelling on the scalp will kill the larvae within hours, as they must keep an air hole open and so will chew through the dried glue to do this, consuming the insecticide in the process.
