Argentine Ants

The Argentine ant (Linepithema humile) is one of the world’s most invasive ant species. It is a native of Argentina, but has since become a Tramp species, spreading throughout the world. It has now been discovered in New Zealand and is present throughout urban areas in both the north and south island.

Common and White Footed Ants

These ants are typically black in colour and some, in particular the White Footed ant will make their nests in walls and roof cavities of houses. Ant numbers can build up to huge proportions and if they get into light switches and power points they will create a short circuit and cause the power fuse to blow. Colonies can number in the millions and a persistent effort with baiting is necessary to bring the colonies under control.

Wasps belong to the Order Hymenoptera, a group of very specialized insects often with highly organized social structures.

Despite the fact that wasps can be very abundant and extremely bothersome at times, there are in fact only four different species that make our life a misery: Two species of Paper wasps – the Tasmanian Paper wasp, and the Chinese Paper wasp – and two species of Vespula wasps - The German wasp and Common wasp.

Norway or brown rat

The Norway rat (Rattus norvegicus) is the largest of the two European rats. It is distinguished from the ship rat in that the tail, which is about 180 mm in length, is thick and shorter than the body, which is about 200 mm in length, and that the ear of this rat does not reach the eye when pressed forward.

Ship or common rat

By contrast the Ship Rat or Roof Rat (Rattus rattus), which is more common, has a tail larger than its body, and ears that cover the eyes when pressed forward. Both of the European species are associated with human activity and are found in houses, tips, waterways and cropland.

Rats have a major impact on New Zealand’s wildlife because they eat native animals and their eggs. They also eat a wide range of native fruit and plants, which puts them in competition with native wildlife for food.

Norway rats are large enough to kill nesting adult seabirds and prey on animals that live, roost or nest close to the ground.

Ship rats are causing the most damage to our wildlife because they are good climbers, so they are able to get access to most bird nests high in trees.
