How do ants live?

Ants are social insects living in colonies. Usually a colony has three distinct castes: queens, workers and males. Each caste looks different and has a different job.

What does the queen do?

The queen lays eggs. Depending upon the species, a colony may have only one queen or they may have several. The colony protects the queen and she never leaves the nest.

What do workers do?

The larger major workers look for food and guard the nest. The smaller minor workers expand the nest and tend the eggs and larvae.

How are new colonies made?

A few times during the year, the queen produces winged males and females that leave the colony to start a new nest.

Identification of the right species of ant is very important for the type and duration of control. Make sure to have ants properly identified by an entomologist.
