killing bot fly eggs/larvae

[Rosemary Hoffman]

Our 10 week old Australian Cattle Dog puppy (or is she an Australian Cattle
Puppy) managed to pick up a bot fly larva which infected her cheek.  We have
hoardes of squirrels living in the Slash Pines in our back yard which become
infected with the critters.

Does anyone know how to kill remaining eggs?  I've considered using a flame
thrower, although the neighbors would think I was over-reacting.
