The ant colony can be found under rocks and down spout drains around the house. These ant will travel following a pheromone trail moving into the inside via cracks in the foundation, siding or brick.
Colony nest may be composed of several hundred but usually average 2000-10000 ants. Colonies have the ability to grow to 100,000 ants. Furthermore, the colony has multiple queens producing young.
Odorous ant colonies will produce 4-5 generations a year and may split (bud) into new smaller colonies. These ants will also swarm in early summer sending out reproductive to begin new colonies. If the colony is disturbed such as picking up a rock the colony is under the colony will immediately move to another location.
