Pavement Ants are small ants, about 2.5 to 3mm long. Black-brown in color, with lighter legs and antennae. They can be identified by two spines on the back, two nodes on the petiole, with parallel lines on head and thorax.
Pavement ants find their way into buildings while out foraging for food. Their nest can be found outdoors under stones/rocks, along curbs or in cracks of pavement such as drive ways or patios. Nests can been found indoors as well, under floors, inside insulation and within walls.
