Odorous House Ant Control

Odorous house ants are not only smelly, but they are also quite small, measuring approximately 1/8 inch long. They have dark brown or black bodies with an unevenly shaped thorax. They have a single node on their petiole, hidden by their abdomens. However, the true telltale characteristic of the odorous house ant is unquestionably the foul odor they emit when their bodies are crushed. It smells like rotten coconut. Odorous house ants like to eat sweets and are especially fond of honeydew. They are known to move their nests every three months or so in response to rain. Indoors, odorous house ants nest near moisture sources, such as in wall voids near hot water pipers, in heaters, beneath leaky fixtures, and inside wood damaged by termites. Outside, odorous ants are often found in exposed soil or under stacks of firewood.
