Hey Jen,
Over the years i've been around people that have been bitten by different types (pythons) and ones that have latched on, i've blown on them and they have released. The hate it. At first i thought the would go for my face when i've been that close to their heads blowing on them, but they release and cringe or put their heads down and away from the blowing, they've never struck at me.
Sometimes you have to blow a few times before they will let go, the worst was my baby spotty, she mistook my finger for a pinky as i was preparing her for a feed, she smelt it and got excited, latched onto my finger and wouldnt let go. I blew and blew and it took about 10 breaths before she let go. Its usually quick, safe and wont break fangs.
