Recently some of our customers are being lured away with claims from other companies that they can "get rid of Argentine Ants for good" that they will "never return".  Well that is simply not true. 
Unfortunately they are here to stay and the only solution we have is to try and control and restrict their activity.  And how do we do that you say?  By applying the proper chemicals and by timing.
In fact, Argentine ant colonies are often so large (biologists call them “super colonies") that it would take a community effort to get rid of Argentine ants once and for all. You see, the reason these ant colonies get so big is because their similar genetic makeup allows ants from what would usually be competing colonies to travel amongst one colony or another. In fact, they will even “team up” with each other, thus creating the feared super colony, with literally millions of workers and thousands of queens.  Researchers found a super colony stretching from NC/SC state line to the outer banks! 
Until scientists come up with a way to finally rid our local habitats of these foreign invaders, here are some things you can do to help control Argentine ant populations on your property and in your home.
Argentine ants only need 1mm gap to gain entrance into your home so your best line of defense would be to close all gaps by caulking and weather stripping your home.  Trim back all limbs from bushes and trees that may be touching your home. Keep all vegetation debris cleared and away from the foundation of the home.
If you want to try a chemical free way of controlling ants, try talcum powder.  Not sure why this works but according to Grandma it works!  Just sprinkle some talcum powder around the baseboards and windows, where ever you may see them.  It should reduce the activity in 4 to 5 days.
Of course there is the Boric Acid and sugar water treatment so many have heard about.  Well here is the receipe if anyone wants to try it.  However you need to remember, too weak of a solution it will do no good and too strong will kill the foragers before they can get it back to the nest.  Take 4 teaspoons of boric acid, 3 cup of hot water ( to dissolve the boric acid and sugar) and 1 cup of sugar.  Leave the mixture in shallow plates around the area where you are seeing activity.  Let us know what happens!
