Unless you have no reaction to getting bitten you DO need some kind of glove. You want to be able to take a bite and not flinch or pull your hand back. The snake needs to learn that it can't influence you with hisses, bites or strikes. You must be persistent and show the animal that you aren't thwarted by it's aggressive attempts. Having a glove on not only protects from the bites, but also for most people keeps them from pulling their hand back too much. What I've done with aggressive animals is to have one glove on, pull the snake out with that and once the animal calms down use a non gloved hand to gently touch the animal. Persistence is the key.
