What is the most humane way to kill a cane toad?

Like many pests, cane toads are killed in their thousands in Australia every year, especially by community-based 'toad-busting' groups. New research has now revealed the most humane way to do it.

I'm not sure what you are talking about specifically, but I have had eastern hognose snakes for years and I have had to dispatch my share of frogs and toads. If I have to I try to sever the spinal cord at the base of the skull with a very sharp knife. Many people who produce feeder rodents freeze or gas thier feeders with carbon dioxide or nitrogen. I guess it really depends what you consider the most humane. I hope that helped.

Actually this was a link to an article on how to kill reptiles humanely. Many of us have been doing this for years, but it's nice to have scientific confirmation that fridge and then freezer is a painless method of killing reptiles.

Like many pests, cane toads are killed in their thousands in Australia every year, especially by community-based 'toad-busting' groups. New research has now revealed the most humane way to do it.

"We need to offer a humane death to the toads -- it's not their fault they were brought to Australia 80 years ago -- but until now nobody has been sure how to do it," said Professor Rick Shine, from the University of Sydney's School of Biological Sciences.

He is lead author on research showing that a once-popular method, currently outlawed nationally and internationally by animal ethics committees as inhumane, is actually a simple and ethical way to kill a toad. The research by the University of Sydney, Monash University and the University of Wollongong is published today in the journal Biology Open.

The researchers implanted small data-loggers in the brains of cane toads to measure any pain responses. They then put the toads into a refrigerator for a few hours, before transferring them to a household freezer. The toads quietly slipped into unconsciousness as they froze, and their brains did not register any evidence of pain during the process.

Professor Shine said: "This procedure was a widespread method for humanely killing amphibians and reptiles for many years until about 20 years ago, but animal ethics committees decided it was inhumane because the animals' toes might freeze while their brains were still warm enough to detect pain. However, our work shows that in cane toads at least, the toad just drifts off into torpor as it cools down, and its brain is no longer functioning by the time its body begins to freeze."

Researchers generally kill animals like cane toads humanely by using specialised chemicals, but these chemicals are not available to the general public. The research provides a simple solution to a difficult dilemma for the Australian community in areas that struggle with large populations of cane toads, such as in the Kimberley region of Western Australia, the Darwin region of the Northern Territory, and coastal Queensland.

"Current ethics regulations recommend that the general public kill cane toads by hitting them on the head with a hammer -- but a slight misjudgement may result in severe pain for the toad, and a splash of toxic poison up into the hammer-wielder's eyes," Professor Shine said.

"Popping toads into the fridge for a few hours to cool down then moving them to the freezer beside the ice cream is kinder and safer for everyone involved."

Interesting!
If vet isn't an option, I've used blunt force head trama; did the fridge to freezer once but had later read from AVA that they may still feel the pain of the ice crystals forming. I assume this would also be for snakes? I do try to tell others to always fridge first so the reptile is in more of a stupor and not likely to feel the pain instead of putting directly into the freezer, glad to hear this is probably good advise I had been giving! lol

In my opinion the fridge section is key - they go into a sleep-like state before being frozen. I wouldn't like to put an active reptile into a freezer.
