The Odorous House Ant is approximately 1/8-inch-long and appears to be brown to black in color. Its waist is one-segmented, and it has a hidden node. Odorous House Ant colonies may be composed of several hundred or up to 100,000 ants with many queens. Inside these ants usually construct their nests near moisture in wall voids especially around hot water pipes and heaters, around sinks, and cupboards. Outside they are often found in the nest of larger ants, in exposed soil, but mostly under objects such as stacked lumber, firewood, bricks, rocks, stones, or pavers. These ants prefer sweets but also eat live and dead insects and foods with high protein content and grease such as meat and cheese. When disturbed the Odorous House Ants run around in an erratic manner with their gaster (rear end) raised up similar to that of the Acrobatic Ant.
