Pest Detective is an online tool to help people in New Zealand identify the presence of pest animals.
Pest animals are often nocturnal and hard to spot. They leave tell-tale clues that tell us they are in the area.
Droppings can look different depending on their age. Compare these fresh possum droppings (top) with the older dried ones (below). Although these droppings are clumped together, remember that possums also produce their droppings as single pellets.
See these photos and more on possums.
Did you know that hedgehogs are predators? They harm New Zealand’s ecology by eating our native invertebrates, native frogs and lizards and even the eggs and chicks of native ground-nesting birds.

Latest from 'On the case' pest detection news
18 February 2016
This year, we will be adding eleven more pest species to our line-up of culprits, thanks to the generous support of the New Zealand Lottery Grants Board.
Dama and Bennett's wallabies will be amongst the newly featured species. They currently occur in areas of Otago, Canterbury, Bay of Plenty and Waikato, and their distribution and impacts are being assessed pending a decision in September 2016 on their 'unwanted organism' status in New Zealand.
