If you're skittish, that is probably isn't helping. I would think that if it is able to strike and you back off, it will keep doing that since it works.
To avoid taking a bite, you could try using a small hook to lift it out of the enclosure and into your hand. Most will calm down once they are being held. My breeder warned me about how nippy my little guy was, but using this guy's approach (https://youtu.be/f-TjNKrsQEQ) he's actually never struck at me in the three months I've had him, and is a very calm handler now.
