Inside, these Ants usually construct their nests in wall voids, especially around hot water pipes and heaters, in crevices, sinks, cupboards, etc. Outside they are found in exposed soil, usually shallow, often located beneath a board, brick, stone walk, etc. They are most likely to enter buildings when their honeydew supply or sweet supply of food is reduced by natural occurances such as rainy weather or autumn leaf fall.
