Scientific name: Tapinoma sessile

Odorous house ants are small (smaller than a sesame seed), brown to blackish ants. One of the most easy ways you will be able to identify an odorous house ant is by their smell. When you crush an odorous house ant, they smell like rotten coconut. If you have never smelled a rotten coconut, feel free to smash an odorous house ant. Some people also describe the smell as rancid sweet butter.

General Information

Odorous house ants live outdoors until times get hard. If they cannot find aphids and scales for their honey dew, they will move inside. Large rain storms can be another event that will force the ants inside. Once indoors they will make their nests inside of your wall voids. They have also been known to make nests under carpet and behind paneling. Outdoors, you will find their shallow nests under logs and rocks. Odorous house ants love sugary food like baked goods and cereals. If sugary foods cannot be found, they will eat meats and grease. One of the characteristics of an odorous house ant is its panic behavior. If disturbed, an odorous house ant will raise its abdomen into the air and move with erratic, drunken movements.
