Odorous house ants, sometimes called odorous ants, are small, measuring 2.4 to 3.3 mm in length. They have dark brown or black bodies with one node on their petiole, which is hidden by their abdomens. Odorous house ants have an unevenly shaped thorax when viewed from the side. The most distinguishable characteristic of odorous house ants is the smell of rotten coconut that is emitted when their bodies are crushed.
Behavior, Diet & Habits
Odorous ant nests are found in a great variety of situations. Inside buildings, they are often found nesting in the walls or beneath the floor. They are most likely to invade buildings during rainy weather. Odorous ants travel in trails, foraging day and night.
Outdoors, odorous ants often feed on honeydew, a sugary waste produced from sap from feeding insects such as aphids. Inside buildings, they prefer sweet items but will also feed on meats and grease.
