As regards the hairdryer method .. apart from repeating it numerous times ...the key for many is to have the viv door ajar , rat on tongs , 10 second hairdryer blast and offer INSTANTLY ..... the slightest delay and the heat escapes ... you're dancing a cool target for 30 minutes .. better a hot one for 6 seconds then reheat and then re-offer , dance a few seconds , reheat and so on ... if it's gonna work the snake you can see the interest building up in the snakes twitchy behaviour .. that said more often than not they strike the first or second time ..
Have you tried leaving the rat near the viv for a while before offering?
Offer at night with dim lighting ?
Anyways good luck !!!
