Usually, bites are due to Stupid Handler Tricks (SHTs). These include: startling the snake, hands smelling like Food, grabbing the head, etc. Some snakes are just nippy.
I have a nippy snake who is treated with great respect. He's only connected with me once, but he's struck at me repeatedly. Before I got him, he was only used for breeding and lived in a drawer, so he didn't get much socialization. He's gotten better, but I still use the cage hook to get him out and control his head while I handle him.
The bite was about 4000 pounds of pressure in a nanosecond. I bled profusely, THEN it hurt like holy heck. I immediately washed it with an antibiotic wash (Band-Aid brand) and smeared it with Neosporin (after securing the snake, of course). It throbbed for a week but healed with no scar.
I would HIGHLY RECOMMEND getting a cage hook. Go to tongs.com or some other place. It's indispensible, even if your snake is docile. Snakes are still wild animals and can be unpredictable.
Calm, deliberate movements with gloved hands are the way to go. You may also want to wait to handle the snake when you notice that it's already in motion - BPs are "twilight" hunters, active in the early evening.
It's been a year, but I've gotten Frank to the point where he accepts being tailed. The hook goes under his neck while I hold his tail. I can move him around quite easily, and the hook keeps his head where I want it (away from my hands and face).
>*** How can you tell a male and female apart without probing?
No way for sure without probing or observing the animal laying eggs. Even two males may mate with each other, so mating behaviour is no guarantee. Get an expert to teach you how to probe.
