 Charter # 133




Argentine ants may be one of the few ants whose colonies don't fight. Each ant knows it belongs to a distinctive colony, but will not fight an argentine ant from another colony.

  • Argentine - Native to Argentina and Brazil was introduced in the 1800's on coffee ships.
  • Live in moist areas near a food source
  • Can have multiple queens in a colony
  • Aggressive, will usually eliminate other ant species.

There are several queens in a colony.

Ants usually nest in the top 6 feet of soil when nesting in the ground.

Ants are social insects, they live in colonies where there is a division of labor among the colony members. Ants may have sub-colonies. The ants have 3 distinct castes: workers, soldiers and queens.

Ants are mainly nuisance pests. Some are of health or economic significance. Some ants have a rather powerful sting as does the imported fire ant. Some ants like the carpenter ant do some damage to structures by hollowing out a place in the wood for their nest.

Ants have a "pinched in" waist, while termites have a broad waist (the abdomen is broadly joined to the thorax).

Ants use their mandibles for almost everything; biting, pricking, piercing, cutting off heads, building, sawing, gnawing, cutting, carrying, leaping and even bounding, but never for eating.

The smallest ant is 0.8 mm long, and the largest 1 5/8 inches.


Most ants are omnivorous which means they eat almost anything, including insects, honeydew, sweets, greases, oils, vegetables, and bread. Once food is found they leave a pheromone trail to lead others to the food source.

Ants have a very narrow esophagus that will not admit even chewed up particles of food. So the chewed up food is fed to the larvae. The larvae then digest and regurgitate it for the adults to eat.

Ants will only send out 10-12% of the colony to forage for food.


The ant has a complete life cycle, egg , larva, pupae, adult. From egg to adult takes 6 weeks to 2 months or more depending on the season, temperature and species.

The female normally mates only once in her lifetime, which she may live and lay fertilized eggs for many years.

The worker ants are sterile.


Most infestations of ants can be controlled with the regular Pest-A-Way Barrier. However, in cases of heavy, difficult infestations a combination of residual barriers and baits may be used.
