Ants can smell well with their antennas. They are not able to smell with a nose because they do not have a nose. They are able to smell with the antenna's on the top of their head.

It's probably hard to imagine something as small as an ant being able to smell the way we do, isn't it? But in actuality, ants have an entirely different way that they smell. Ants sense of smell comes through their antenna. You can find more information here: http://www.lingolex.com/ants.htm...
