Ants are one of the most successful groups of insects. They are social insects that live in colonies which are usually located in the ground, but they may enter buildings for shelter and/or food. Ants feed on practically every kind of food, but those entering homes are looking for sweets and/or protein containing substances. As with many other insects, moisture is the key factor that determines the sub-ability of a potential harborage site. Ants will exploit situations that have sufficient moisture, provide shelter, and have a nearby source of food. Moisture sources may be stones, wood or other objects on the ground that physically retard moisture evaporation and/or act as a heat sink and cause condensation on their underneath side. Other sources include mulch and/or dense vegetation and traps moisture underneath it and/or retards drying air currents, in addition to the free water room downspouts, overflowing gutters, poor grade, leaking faucets, irrigation systems, etc. The food comes from honeydew-producing insects that feed on plants and the many insects that are themselves attracted to areas of high moisture. Such conducive conditions are most common in the landscaping around the foundations of structures.
