The cornfield ant is predominantly found in outdoor locations.  To the untrained eye they are recognizable by their habits more so than by their appearance.  In the Calgary area, cornfield ants build visible, crater-like nests near or underneath bricks, stones, sidewalks, cracks in pavement and rotting logs. They also leave tell-tale piles of soil where they have excavated.  Often a pest to the putting green and immaculate yard, they will also make themselves busy foraging sweets and meats from the home or business. If there are cornfield ants inside, undoubtedly there is a ready food  source that needs taking care of.
