Pavement Ants

The pavement ant earns its name as they nest beneath and along the sides of pavement: patios, driveways, sidewalks, foundations of homes.

Appearance:

Pavement ants are dark reddish-black with limbs that are lighter than the rest of their body. Their antennas are segmented into 12 sections and bulge at the very tips. Their head and body have straight grooves of hair that run down from top to bottom, and they reach a length of 2.5 to 3 mm.

Habitat:

They nest under stones, cracks in pavements, along curbs, and grassy areas along sidewalks. In some cases they’ll nest in mulching or open soil near buildings.

When they nest indoors, they’re commonly found in walls, insulation, and under the floor.

Diet/Behavior:

They aren’t picky and will eat live or dead insects, honeydew, pollen, grease, and meats.  Pet foods or any food dropped on the floor will quickly covered with pavement ants.

They search for food for their colonies by setting up trails that connect the food source to their nest.

They’re capable of stinging, but they normally will continue to carry on working unbothered. They’re not aggressive and will most likely choose to run away rather than defending their territory.

Interesting fact: 

Aren’t native to the United States, but one of the most frequent species around, especially in the Midwest.
