Ants are social insects that live in organized colonies. The tropics are their main habitat. Besides the ants that cause damage or are bothersome to humans, there are a great many species that can be considered beneficial in various ways. The red wood ant, for example, plays a major role in pest elimination.
An ant colony is characterized by a well-organized work-sharing system. Whereas the queens are responsible for egg production, the many workers build nests, gather food and nurse the brood. Male ants inseminate the queen, after which they die. The developmental stages include, egg, larva and pupa, from which last stage the adult ants then hatch.
Ants are possessed of a very good sense of smell that helps them gather food. Communication within the ant colony is also based in large part on smells.
In human settlements, those ants are considered a nuisance that build their ant paths through house and kitchen to food stores. They cause damage when they establish nests in various parts of houses and other buildings, thereby damaging building substance. Pharaoh ants are also significant hygiene and health pests.
