Pavement ants are very small, and is approximately 1/10th to 1/8th inch in length. They have one set of spines that stick up from their middle body section. They are dark brown in color. They have a stinger in the posterior section and can invoke a painful sting. They primarily feed on other insects, and honeydew, but can invade your home and head straight for the pantry to nibble on nuts, berries, eggplants and any greasy items you may have stored.
They have derived their name by the habit of building nesting sites along concrete walks, driveways, joints in concrete, and along the foundation of your home. Sometimes they will leave little craters along the openings of their nests however they may just displace the soil along the area that they emerge from. They also nest under rocks or bricks that may be in your yard. The winged forms of the Pavement ants are attracted to light sources, and during the mating period (springtime to mid summer) may be found around porch lights. Inside the house they can be found around any heating system such as a hot water heater or furnace.
A careful inspection by a trained technician can reveal the source of the infestation and determine the best approach to resolve the problem.
