Understanding the type of enemy who has invaded your home is vital in the defense mechanism used against their attack. A blind retaliation may leave you in a worse situation and possibly result in the unnecessary use of poisons that are toxic to the environment. Different species of ants have unique behaviors and pose their own distinct set of problems for a homeowner. For example, a black ant will set up its camp outside. It will come inside a residential area in its mission to find food but there is little concern that it will remain inside and establish a colony. Black ants do, however, pose a threat for biting. If you spot a black ant inside your home you can trace it back to its location outside and destroy the colony.Another type of ant that is similar to the ghost ant is the pharaoh. Both ants emit a particular odor when squashed and are very small in size. There is a different protocol followed to address the pharaoh ant than the one used in dealing with the ghost ant.
