All methods of eliminating cane toads are apparently banned for cruelty reasons. I'm not sure how much is law. Probably cricket and golf are out. The only method which is supposedly humane is freezing them. Mind you, it doesn't seem humane to humans who have to put them near their food products; and it requires handling with greater potential for spray in the eyes.
I personally think it crueller to freeze the blighters seeing as they have obviously migrated to Queensland for the sunny, warm weather; and to cool them down would be like torture or moving to Tasmania or something. Nothing worse than freezing to death I reckon.
When it's Springtime in the Towers, the chinees are in bloom, the rubbervine's entwining around the lantana too. I look inside the freezer, hungry for a bite, take out a bag of canetoads, and cook them in the fire. (To tune of Springtime in the Rockies)
Here's my experience on the warm night. http://forum.beemaster.com/index.php/topic,36333.msg304831.html#msg304831
