Ants live in groups called colonies, and may nest underground. If they live in a home, they will live behind baseboards, moldings, countertops as well as inside walls. If ants come in a north direction, it indicates happiness, The south shows signs of profits, the east that you will get some negative news, and the west that you will soon go abroad. Ants play an important role in the environment, and allow water and oxygen to be able to reach plant roots.
