Appearance

  • Workers 2-4 mm long.
  • Queens up to 15mm long.
  • Dark brown/black in colour.

Biology

  • The queens lay a large number of eggs which hatch after 3-4 weeks, with the adults emerging around 5 weeks later.
  • Between June-October the mature males and females leave the nest in order to mate. The ants have wings which is often why 'flying ants' are seen during this time of year.
  • The males will die off after mating with the females hibernating (generally in soil, voids or under patios) over the winter.

Habitats

  • Ant colonies are found in a wide range of locations including gardens, under patios and floors or in, and around buildings. Nest entrances and exits are often identified by small piles of fine soil or sand.
  • Worker ants will often enter buildings in order to forage for food and once a source has been found a distinct trail of ants can be observed. Ants can be discouraged by cleaning up any sweet or protein based food sources.

Treatment

  • Domestic ants can often be controlled in just one treatment using a variety of products.
  • As well as dispatching the ants visible to the naked eye; achieving long term control requires elimination of the colony source below ground or within a structural void.
