An ant's sense of smell is stronger than a dog's

Have you ever wondered how an ant appeared to notice you and start running in the opposite direction before you were even close? You have probably heard about how bad the eyesight that ants have is, so how do they know when danger is near? It turns out that ants have a remarkably strong sense of smell, even stronger than that of a dog. Smells run an ant's life. Ants leave pheromone trails in order to find stashes of food and find their way back to their nest, and without a superstrong nose, ants would have a hard time finding their way to and from the home.
