The Sydney University Shine laboratory is labelling the cane toad trapping program set up across the Northern Territory as useless.
The Martin Government has invested hundreds of thousands of dollars in the Frogwatch trapping program and is offering residents a $30 rebate if they buy an official toad trap.
But researcher Ben Phillips says the size of the toad front is already too large to combat and that the pests breed more when isolated.
"They have huge numbers of eggs and they survive better when there's fewer toads around," he said.
"When you reduce the numbers of toads you will tend to make it easier for them to replace themselves."
