Argentine Ant Control

Linepithema Argentine AntArgentine Ants are a serious and persistent pest in Los Angeles and the Southern United States. They’re native to Northern Argentina, Paraguay, Southern Brazil, Uruguay and introduced to Japan, Europe, New Zealand, Easter Island, South Africa, Hawaii, Australia, and the United States.

Ants are ranked among the world’s 100 worst animal invaders.

A worker Argentine ant’s length is around 3 mm and queens are 2-4 times larger than the workers. Queens are the only ones who lay eggs and they seldom or never develop into winged form. Production of male Argentine ants seems to be controlled by the quantity of food available to the larvae.

Argentine ants can start a new colony with 10 workers and 1 queen. They will set-up rooms in cracks, ground, timbers, or in between spaces of boards. Argentine ants have low ability in digging deeper nest but if they see deeper abandoned nest, they will take over the space.

There are 3 supercolonies discovered in the world according to a research in 2009. They are the “Californian large” colony in America that stretches 900 kilometers along the coast of California, the supercolony in the west coast of Japan and the supercolony in Europe along the Mediterranean coast stretching 6,000 kilometers.

  • There are several reasons why Argentine ants are difficult to control:
  • A colony has several queens, they will only scatter and form new colonies when you use broadcast spray.
  • Argentine ants are not territorial; they can spread quickly because different colonies don’t fight.
  • Argentine ants are relatively mobile, they can quickly move from one place to another.
  • Calling pest control professionals is the best decision to eliminate Argentine ants because they have the proper knowledge and training in IPM tactics. IPM or Integrated Pest Management is an approach with greater chance of eliminating Argentine ants. This method includes: identification, inspection, sanitation, exclusion as well as chemical strategies.
