I have only been bitten once by a bp that actually hurt, but it was my fault. I was feeding a 2600g female and she missed the rat and got my hand. But the rest of the bites have been nippy babies, and very few times has it even drawn blood. Animals that suck more that a bp bite, just about anything you can think of; Tokays have a good bite, Jelly fish stings ( I know not a bite but still been stung twice not fun), cat bites, dog bites, bee stings, hermit crab pinches, and the list goes on and on.
