What are white footed ants?

The white-footed ant (Technomyrmex Jocosus Forel) is a species introduced to New Zealand. It has become well established, both outdoors and indoors and can be found throughout greater Wellington, Wairarapa, and the Manawatu. The white-footed ant workers are black to dark brown and are 3.0 mm to 3.4 mm long. They are called white-footed because of their yellowish-white leg extremities, which are clearly visible with a magnifying glass.


White Footed Ant Nesting

White-footed ants’ nests can be commonly found in the greater Wellington region, inside a building’s structural cavities (roof-space, sub-floors and wall voids), where they are protected from environmental extremes. An infestation can consist of one or more satellite nests that are interconnected and may contain up to two million individuals. Ants within the same colony may be found nesting at several locations around the same structure.

There are many queens in an ant colony, which may have numerous ‘satellite’ nests branching out from the main one. The ant nests don’t have any structure, they just occupy surfaces inside cavities. The white-footed ant has not been reported to cause any direct structural damage the way carpenter ants do in other parts of the world. However, they are often found nesting in warm places, such as electrical power points or switch boxes, which can result in them short-circuiting.

White Footed Ant Reproduction

New colonies of white-footed ants are formed by swarming and budding. Swarming happens usually around the start of winter. Winged adult males and females are produced by the colony. They fly away en masse to start new colonies elsewhere. Budding is when wingless reproductive ants, along with a large number of worker ants (who carry larvae and pupae), crawl away en masse to form a new colony a short distance from the parent colony.

White Footed Ant Diet

Parasites on outdoor plants, such as aphids and scale insects, secrete honeydew. Honeydew is a popular food source for the white-footed ant. The White-footed Ants protect the parasites from predators, which results in increased damage to your plants. The ant also gets its sugar fix from the nectar of some trees and shrubs.

Vegetation favoured by the white-footed ant in the greater Wellington region is the Virginia Creeper, the Norfolk pine, and the camellia, citrus, Manuka and Pohutukawa tree. Occasionally you may find the ants feeding on dead insects, pet food or household food scraps, in these situations they are seeking protein.

Only one part of the colony forages for food and unlike most other species, they don’t regurgitate the food they have eaten to the non-foraging ants. Instead, they digest the food and produce trophic eggs (unfertilised eggs) that are consumed by the rest of the colony (adult and larvae), or stock piled for future use. These eggs are poison free, which is why bait will not eliminate white-footed ant colonies.

White Footed Ant Prevention

Your objective is to starve the ants, which you can achieve by removing all possible food sources. You can clean all food preparation areas and store food in containers with tight-fitting lids. Keep your roof and the exterior walls of your building clear of vegetation and treat against aphids and scales on outdoors plants. Aphids and scales secretions are the preferred source of food for the white-footed ants. Ant trails in the garden will usually lead you to the plants that need treatment. Keep recycling and rubbish bins clean.

White Footed Ant Treatment

We can perform exterior residual spraying, which will control the ant colonies in the structural cavities of the building. The treatment consists of an application of a non-repelling residual insecticide to all ant trails outside the house. The material used is Termidor SC or an equivalent.
We can also provide interior residual spraying, an optional and free of charge treatment we can carry out in conjunction with the external treatment. It is only necessary if you don’t wish to wait for the results of the exterior treatment and don’t mind chemicals in your living or workspace. The treatment consists of selective interior spraying of an insecticide barrier around the skirting, some windowsills, affected cupboards, and entranceways. The material used is Demand SC or an equivalent.
