I used to work as an exterminator, in Texas and dealt with several variety of Ants, and can tell you this. There is no real stopping, ants.
Ants are mainly after two things, Food and Water. Try keeping everything as clean and spic and span as possible. They work by following a trailblazer (scout) that lays down a chemical trail left by the scout, so once you see a trail, kill, them and clean the trail all the way back to their entry point into the house. All you will really be doing is fighting the symptoms of infestation, more than likely they will re-emerge somewhere else in the house. You can contact an exterminator and get some ant baits, that are of a greater chemical stregth, than over the counter stuff. The main thing is to look at their pattern of trails and maybe locate outside, where they are mounding and bait and kill the colony. Also be aware if they have wings, they might termites. Good luck!
