Howabout some .22LR 10/22? Australia looks for ways to end cane toad menace Fri Aug 5, 7:31 AM ET
CANBERRA (Reuters) - Australian scientists were given A$3.6 million ($2.7 million) Friday to find a biological way to combat the rising population of poisonous cane toads.

The pests have spread across northern Australia since 100 cane toads were imported from Hawaii in 1935 in a bid to fight greyback beetles, which were threatening the country's sugar cane fields.
"The cane toad is a blight on our landscape," Australia's Environment Minister Ian Campbell said.
He said the state-owned Commonwealth Scientific and Industrial Research Organization (CSIRO) will conduct research into ways of manipulating cane toad genes to stop tadpoles from becoming adult toads.
"While short-term measures like traps are important to slow the toads down, their capacity to breed means we will not stop them for good unless we find a biological solution," he said in a statement.
Australia has fought the cane toad menace for four decades but has been unable to stop the spread of the toxic creatures, which have highly poisonous sacs behind their heads that quickly kill native animals that prey upon them.
Cane toads now number in their millions and are so toxic that crocodiles, death adder snakes and wild dingo dogs can die of cardiac arrest within 15 minutes of eating them.
Australia's environment department says cane toads have been expanding their range across tropical northern Australia by up to 50 kilometers (31 miles) a year, while they are moving south by about 1.6 kilometers (1 mile) a year.
Female cane toads can lay 8,000 to 35,000 eggs at a time and may produce two clutches a year. The toads reach maturity within a year and have a lifespan of at least five years.
