Hey Diamonds and Funkstaa,
I've still not held a BIG carpet yet so I haven't been inducted in to the club properly yet... But thought I might have some helpful advice...
I have my Stimson who "bluffed" a few times when I first got him, (and have to admit, that scared the crap out of me at the time!) but it was after watching a mate just walk up, no hesitation, picked him up and start playing with him, that I decided I was being a big "jessie". I started picking him up expecting that he wouldn't bite me, and he's never bitten me since, and so to date never drew any blood...
My little juvy carpets on the other hand, from a couple of months old when I got them, both were able to draw blood (albeit a tiny needle prick dot of blood most times), but it reignited the instinctual fear of bites for me... Just couldn't help being a little nervous, mainly just not wanting to react irrationally, for example jerking my hand away and potentially injuring the snake...
Someone earlier posted along the lines of just going about your business, and then quickly deciding you're just going straight over and picking it up! I guess it's not that simple if like me, you need to pick up and move the click clack, which alerts the snake to your presence, gives you time to work yourself into anxiety etc...
But I've definitely found, that the more you hesitate, even if bringing your hand in really slowly to pick him up, they seem to perceive the hand as threatening, coil up, strike at me, and as a result I reach for the hook, then once out, no more problem...
I have successfully convinced myself to be less of a "Jessie", and have begun timing a quick but gentle grab when the head is facing away etc, sometimes even using one hand for distraction whilst the other picks up the body. I've found that once I've got a hold of the body, he's much less interested in coiling to bite, but instead appears eager to escape as a result of the surprise of being touched maybe...
Either way, after a couple of seconds, he's calm and I'm not bleeding!
I considered just putting my hand in with my eyes closed to purposefully get a bite, I think it was the fear that I might still jerk my hand out if bitten that turned me away, but if you got someone else with a bit of a sadistic side to hold your hand firmly in there... lol
Best of luck anyway!
