A new bait and trap system, known as the Hog Hopper, could soon see feral pig numbers across the Top End greatly reduced.
The Invasive Animals CRC has been designing the system for over five years.
The device has even received attention from agricultural officials in the United States.
The CRC's Professor Steven Lapidge says the trap has been tested to ensure only feral pigs can access the bait.
"We present the bait in a metal hopper, which...requires the nose structure - the strength - of a feral pig to lift the device.
'We train them to do that for a week or so with non-toxic bait first.
"The bait itself, it's like a small salami...but it smells like rotting fish...so it puts off the herbivores."
