Pest Management

​​​​​​​​​​​​​​​​​Hamilton City Council’s Parks and Open Spaces Unit is responsible for the management of Hamilton’s 200 parks and open spaces.

A crucial part of the unit’s role is the control of pest animal species such as rats, possums, mice and rabbits.

The work is undertaken in collaboration with Waikato Regional Council and focuses on protecting Hamilton’s green spaces, particularly those with ecological significance.

This work is undertaken by a private contractor working on behalf of Council, to a specific schedule which encompasses a range of parks on either a regular or as-needed basis.

From 16 January, a new programme of pest control will commence. The programme will see intensive pest control undertaken in selected parks for a three-month period. This programme will see a particular focus on significant natural areas;

* Large parks including dog exercise areas or playgrounds. Pest control will be undertaken in the margins of these parks, however it will be well away fro​​m off-lead exercise areas and playgrounds.

The primary tools for pest management are bait stations and traps, and are site-specific depending on the pest species identified and the community’s use of the parks. 

Although the Council’s contractors place traps and bait stations in areas of parks which are not generally high use or readily accessed by the public, residents who use these parks are strongly advised to keep themselves, their children and any pet animals under close supervision.  The pest control work is closely monitored and Council’s contractor uses methods which are sensitive to the use and popularity of the parks. Parks where pest control is underway will feature clear signage which identifies the type of bait or trap in use.

It’s important members of the public – particularly dog owners and parents with small and/or inquisitive children – are aware of what these traps and bait stations look like.

The traps and bait stations used in our parks are pictured below.​

New Zealand Biosecurity Services has specific methods for controlling pests in Hamilton’s parks and natural environments.

The company uses lower residual baits for riparian margins – for example along the Waikato River and the city’s various gully walkways - and bush areas to ensure the safety of pets, park users and native birds of prey. The company’s operations target significant natural areas prior to the native birds breeding season to ensure these bird species have a best chance of breeding / nesting.

The work enhances broader cross-organisational efforts to protect and enhance Hamilton’s biodiversity, and increasing the presence of native species in our city.

The program has been initiated in significant natural areas sector (see earlier list of parks), and over the course of the year, the focus of pest control operations will change. The bait stations and traps will be moved from one group of parks to another.

Pest control operations – Wasps​

​Between January and April 2017, the Council's pest control contractor will undertake isolated control of wasp nests confirmed on our parks and reserves with the use of Vespex.

Vespex is a protein-based poison containing Fipronil which wasps feed on and transfer back to their nest. The poison is distributed throughout the colony which quickly destroys the nest. Bees are not attracted to Vespex and it is considered low risk to birds, people and pets.

Vespex is placed in yellow bait stations attached to trees in inconspicuous locations. Signs will be erected in areas when Vespex is in use.

Pest control operations are permitted under The Reserves Act 1977 and are a fundamental part of the Council's park management.
