Nylanderia fulva, is an ant originating from South America."
Boric Acid Argentine Ants
... A more effective way to deliver boric acid to Argentine ants is in ant bait.
Ant bait is made from a food that the ants will accept.
The bait has a small amount of boric acid mixed into it.
The workers take the bait back to the nest and share it with all of the other ants.
The first step in controlling Argentine ants is to inspect carefully.
Follow the trails of workers to find the nests.
Argentine ants often make satellite nests, so it is important to find as many of their locations as possible.
Put the ant bait beside the trails so the workers can find it easily.
Make sure that children and pets cannot reach the ant bait.
Because the Argentine ant colonies are very large, it is important to use plenty of ant bait.
If any of the queens survive the treatment, they will produce enough eggs that the ant population will be back to the original size in a short time.
After all of the ant activity has ceased, boric acid dust can be applied into the weep holes and the voids of exterior walls.
This can help prevent future Argentine ants from entering the home.
Put firewood up on a rack and store it away from the foundation.
Rake mulch and dead leaves away from the foundation to make a clear space that is 12″ to 24″ wide.
This will help discourage Argentine ants from nesting next to the foundation and entering the home.
It ain't much help, but it's better than nothing.

“You forgot what is probably the best method of which I am aware... nematodes. Those parasitic little buggers won’t bother the adult ants, but can totally wipe out a colony by eliminating the larvae and queens. Of course, if you’ve tried chemicals and failed, you’re screwed - the pesticide residue will kill off any nematodes you add, and who wants to live with electronics eating ants for a year or two while you wait for the soil concentrations to drop off?
Also, while I’m not as confident in it, I suspect that DE (diatomaceous earth) would work quite well as a border control in places where you can keep it dry (such as along the baseboards of your house, especially useful while waiting for the nematodes to do their thing). Just make certain you use food grade DE - pool grade has been treated in all sorts of nasty ways, including high heat that causes the silica to melt and recrystallize, making the dust dangerous to humans as well as insects.”
Don’t know if this works. I don’t have these ants. He is referring to Parasitic, not root knot nematodes. Spray them on the colonys, wash them in. Hunt and destroy time. In theory, they reproduce, they continue on until the food—larvae-is gone.
