This shed is made from tin or well fitting, vertical palings and has a footing. The idea is that chooks can reach the entrance from the perch, whereas devils and quolls cannot. Where attacks by devils or quolls are hard to prevent, the Parks and Wildlife Service may issue permits to trap troublesome individuals for relocation. Usually these permits are only issued where someone's livelihood is threatened, as distinct from where devils or quolls are just a nuisance. More rarely permits may be issued to live-trap and destroy devils.
Some people do take the law into their own hands and set poisons.
However, this is illegal and can result in the unintended deaths of other wildlife such as eagles. Occasionally devils take up residence and even breed under houses. However, devils can be extremely noisy, especially in autumn. The Parks and Wildlife Service would prefer they are left alone but may help remove these 'guests' if you can t tolerate them. However, it is best to wait until breeding has finished in autumn and the devils have left.
