Although vinegar can be used in emergency situation when a large constrictor bites and begins constricting, it should NEVER be used during the process of getting a timid burm to learn to trust its owner. That kind of negative reinforcement will NEVER work. Instead, in order to build confidence I would recommend the following:
1) Get some welders gloves and wear them while working with your burm; if it bites, you won't feel anything and you will learn not to jerk back everytime it does strike.
2) In time, once the snake learns that you are not a threat, keep the gloves on but once you have the snake safely in your hands/arms, take one glove off and let the snake just slither through your bare hand. Let the snake get used to your scent.
3) Eventually, you will be able to take both gloves off once the snake is safely in your hands. And, soon after, you will not need the gloves any more. This process could take weeks or months; just be patient.

>>I was once bitten by my 14' burm and it takes a while to get over. My suggestion would be to keep a spray bottle with vineger in it. If ya spray the snake on the nose with it they let ya go. And it does work, ive used it. Having that nearby should bolster your confidence. Ya gotta remember it was your fault u got bit, not the snakes.
