    Red Pavement Ant - (Tetramorium caespitum)

    A scavenging Red Pavement Ant colony can take over a swath of sidewalk, proving that small things can make a big impact.

    Picture of Red Pavement Ant
    Staff Writer (9/29/2014): The colonies of the Red Pavement Ant are usually seen on sidewalks, or driveways, on concrete or asphalt. Stepping on one results in many ants crawling up the shoe and leg that can potentially bite. They are not poisonous, but their bites can pinch. Their presence is enough to cause people to walk around them and not through them.

    Scouts for a colony will constantly search for food and other resources. Red Pavement Ants often quickly find dropped food items and, in little time, completely cover the food item with their bodies.

    Though ants are typically associated with a fondness for sweets, they will consume any food. Because of this, they can become house pests. If a few scouts find food resources inside a building or home, they will infest the area. There small size and great number make it difficult to control and infestations are best treated by a professional exterminator. Preventative measures, such as sealing cracks in the foundation and removing wood debris from the sides of homes or buildings, may help avoid infiltration. Keeping food contained reduces the likelihood that scouts will find anything worth returning for.

    The Red Pavement Ant is a member of the Formicidae family. Large colonies are built with at least one queen ant laying eggs for a living. This allows for rapid reproduction. Some males and females are winged (called 'alates') and mate in flight. Both genders then lose their wings; males die and females land and begin a new colony. Eggs are laid and cared for and kept underground until they hatch.

    BUGFINDER: What Kind of Bug is This...
    BUGFINDER allows for a quick search of the Insect Identification database by selecting primary color, secondary color, number of legs and the territory / state in question. If only one color is present on your insect, select it again as its SECONDARY color. Remember that the more details you can offer, the better your chances of finding a match. As a rule of thumb, six legs are typical for most insects whereas spiders generally have eight legs.
