    From the wikipedia article on ants (http://en.wikipedia.org/wiki/Ant): [Broken]
    Ants communicate with each other using pheromones. These chemical signals are more developed in ants than in other hymenopteran groups. Like other insects, ants perceive smells with their long, thin and mobile antennae. The paired antennae provide information about the direction and intensity of scents. Since most ants live on the ground, they use the soil surface to leave pheromone trails that can be followed by other ants. In species that forage in groups, a forager that finds food marks a trail on the way back to the colony; this trail is followed by other ants, these ants then reinforce the trail when they head back with food to the colony.​

    And every colony has a unique phermone. Ants don't get confused by foreign trails.

    This is all too interesting, I had this problem the other day in my bathroom; A trail of sugar ants were climbing along the wall. I knew that they follow a trail via scent so I sprayed and wiped along a three or so foot section of their path with deodorant and it had a moderate degree of success.
