Like all insects, Ants do indeed breath. However, unlike humans and other mammals they do not have lungs and the oxygen is not carried by the blood. Instead they take oxygen in to their bodies through openings in the abdomen. This system of tubes, called tracheae and tracheoles, allows Atmospheric oxygen to pass to the tissues. The outside openings of tracheae are called "spiracles". Ants are small enough that they need only a few spiracles and these do not have valves to control the oxygen flow, as with larger insects.
the ants sense of smell is located in the antenae
Yes. Certain ants produce a substance called formic acid, the simplest of the organic acids. Since we usually encounter ants outdoors and not in great groups, this odor would likely go unnoticed. But in an enclosed situation, there is no doubt the odor would be quite noticable to humans since it is very noxious.
When you squish an ant, it releases formic acid, which is a chemical that ants use for communication and defense. The smell that you notice is the result of this formic acid being released, and it gives ants their distinct odor.
Ants will go anywhere that they can find food. They can smell the food in pantries so that is why they go there; it is easy food for them.
Every group of ant has a smell.
