thump it (cheapest) - (stick it in a bag and crack it on the cement) not exactly humane but how humane is throwing it in a cage with a giant monster that will break every bone in its body and squeeze the breath out of it....
dry ice (every time cost) - stick it in a sealed container with it
taser (one time cost) - one good shock from a cattle prod does it for me
A lot more humane than being smashed against cement...
An appropriately sized live prey item will expire via constriction without much suffering within seconds. That is what these snakes were designed to do.
