Description

The worker garden ant is a large ant 3-5 mm in length and dark brown to black in colour. The Queen is about 12mm long and slightly lighter in colour.

Habitat

Normally living outdoors, the ants found indoors are usually worker ants, which are foraging for food for the queen and the grubs. They have found that buildings inhabited by humans are a good source of provision, particularly sweet or sugary items

Threats

Foraging worker ants cause a nuisance as they travel widely in search for food, usually following well-defined trails and clustering around a food source. Ants may cause considerable nuisance occasionally invading food prepared for human consumption.
