Argentine ants are some of the peskiest, hardest-to-get-rid-of species of ants. Normally, while ant colonies tend to be isolated, argentine ants have the ability to form massive colonies by combining colonies, creating a force to be reckoned with.
It is not an exaggeration to say that getting rid of an argentine ant infestation is not an endeavor that can be accomplished by just one person. While the average ant colony has only one queen, super-colonies of Argentine ants may have thousands and thousands of queens, not to mention worker and soldier ants. Thus, the only way to get rid of them is to prevent an infestation in the first place.
Sprinkling talcum powder or diatomaceous earth works well to keep argentine ants out of your home. It is also important to seal up any crevices or cracks in the walls to prevent argentine ants from creeping in. To keep Argentine ants out of your garden, a mixture of boric acid and sugar water may work wonders by luring the ants and then destroying their nests with the boric acid. However, completely eradicating a super-colony of Argentine ants is likely impossible, and you may have to settle for just keeping them at bay.
A safe, natural repellant/insecticide such as EcoVenger® is an indispensable tool in the event of an Argentine ant infestation. More convenient than talcum powder or diatomaceous earth, the child-safe, pet-safe formulas that EcoVenger® uses are free of harmful chemicals, yet as effective as any other brand of chemical-based insect repellant.
