By the nature of their hive system, ants are foragers. They need to invade space to find food that supplies the colony, and ultimately, the queen. They will march far and wide to find sustenance, and if that means invading your home, they will do so. They will gladly steal the crumbs on your countertops and kitchen floor, then they will leave a scent trail so that more of the army can zero in on this new food source. You can spot kill the invading ants, but until you eliminate the colony and the queen, the ants will keep coming back.
