Learning Objectives
After completion of the study of Ants, the trainee should be able to:
Identify key features in the life cycle, habitat and appearance of the
common species of ants.
Given a problem situation for each species of ant, select appropriate control and
management procedures including both chemical and non-chemical.
Before they pupate, the larvae of some ants (carpenter

Ant queens are females. They mate and
raise the first brood by themselves.
Afterwards, they produce eggs for the
