Information on pest control activities in Dunedin.

What we do

The DCC’s pest control in our parks and reserves focuses on possums to protect the vegetation and native fauna from browsing, die-back and predation. For possum control work, we use an experienced contractor who has worked for DCC for many years. In some high biodiversity value reserves, we also carry out rodent, rabbit, mustelid and some goat control. Our contractor also deals with wasp nests in our parks and we will be trialling wasp bait stations early in 2019.

How we do it

Possum trapping is carried out between one and four times a year at each site. The DCC does not use toxins to control possums. Reserves with high biodiversity values such as Ross Creek, Woodhaugh and the Northern Town Belt are targeted up to four times a year. Each operation involves a line of traps (usually the familiar yellow Timms traps, using apple as bait) over four nights. Each day, the traps are set late afternoon or early evening and checked every morning. During the checks, the traps are set off so they are not active during the day. They are then reset later the same day.

Rodent bait stations are hidden among dense vegetation at fixed locations. The toxin is located on a pin inside a closed and protected plastic box. Mustelids are trapped in specially designed and DOC approved wooden boxes. They are only used near some seabird breeding sites. Goat control is carried out once a year by specialised hunters and these operations are publicised on this website. Rabbit control is carried out monthly by our pest contractor.

Why we do it

DCC controls pests to manage the vegetation and native wildlife in our parks and reserves, which also prevents these pests from moving onto private properties.

Predator Free Dunedin

The DCC is one of 20 organisations in the Predator Free Dunedin partnership. Working with Predator Free and the community, the DCC’s pest control will gradually move from the inner city to the surrounding areas, with inner city pest control being carried out by community groups.

  • Flagstaff Possum Control

    TBfree possum control work is being undertaken in the Flagstaff area from 4 March 2019.

    This covers over 2,130 hectares, including Swampy Ridge, Pineapple Track, Flagstaff and Nicols Falls. No 1080 will be used but due to the use of toxin, dog owners should keep their dogs on lead in the area until further notice. It is likely this will be until at least early 2020.

    A combination of trapping, Feratox and brodifacoum is being used. These toxins pose an extremely low secondary poisoning risk to pets. Bait will be in bait stations or bags, placed no lower than head height and there will be no toxins or traps within 30m or in sight of tracks.

    Ground possum control methods will be repeated in the Flagstaff area over the next two years, with future methods to be decided.

    The goal is to eradicate TB but the reduction in possum and rat numbers will also have benefits for native wildlife. The operation will help to achieve Predator Free Dunedin’s aims to achieve predator free status over 31,000 hectares in the city. The DCC and OSPRI are among 20 organisations in the Predator Free Dunedin partnership.
