Dealing with Cane toads with sound traps

 Namely the mammals are mostly thought initially as being the most affected by traps rather than other forms of control. However, in Australia there are a serious toad issue which can be reasonably controlled with traps, sound traps to be exact. 

The cane toad is a toxic amphibian and when eaten by a predator will poison them. Plenty of pets, from cats, dogs alike will try and eat the toad. And in doing so become poisoned. 

The Australians have found a way of lure these creatures using siren calls into a trap. 
Sounds emitting from a trap, along with light to attract flies, the trap mimics the call of a male toads.  Low frequency with a high pulse rate to be exact seemed to attract both male and female toads. But the most attracted were ready to mate female toads. 
Female toads can lay up to 20,000 eggs per cluck. Removing the reproducing female is far more effective tan removing a male.

The challenge is that toads in different areas across Australia are attracted to different sounds. So one would need to adjust the calling to mimic the local variation. A local dialect if you will!
Ironic to this story is that Cane toads were introduced as a form of pest control for control beetle lavae which ate sugar cane roots. 
The cane toads were  so successful in reproducing that the became a pest in themselves. 

The Cane toad sound traps were an innovation by the James Cook University. Further info about this innovation can be found here:

Here is the UK we do not have such a toad problem. But we do have plenty of examples of invasive species brought into the country in the last 2 centurys. Making themselves at home and pushing the native species to the brink of extinction. There is no finer example of this than the grey Squirrels. The Goodnature traps will be bringing out a Squirrel verison of the traps over the coming months to help with the control of these non native species.
The squirrel traps are currently going through the spring trap approval order process and will be on the stutue books hopefully in early 2018. Here is an overview of the Spring Trap approval order.
