Physical Characteristics

Worker pavement ants are 1/16 to 1/8 inches long and queens are 3/8 inches long. Pavement ants are light brown to black in color, with legs and antennae a more pale color.  These ants get their name from often nesting in pavement cracks.

Behavior

Pavement ants will feed on anything – other insects, honeydew, seeds, plant sap, cheese, bread, nuts, even meat. They like greasy food. Pavement ant colonies are moderately large, containing 3,000 to 4,000 ants, with several queens. They will forage in trails up to 30 feet from their nest, which usually is located near a water source. Pavement ant colonies are hostile to one another, and during warm months, it’s not uncommon to find them engaging in huge ant wars on sidewalks.  Indoors, these usually ground-nesting pavement ants will nest in walls, cracks in expansion joints, under baseboards, and under floors, masonry, and insulation.  Outdoors, nesting may occur under stones, cracks in pavement, along shady lanes, and next to structures. Although pavement ant workers are not aggressive, they can bite and sting if provoked.

Treatment:

As with other ant infestations, seek out the source, where pavement ants are nesting. It’s probably more effective and safer to call for a Clark Pest Control technician, who can achieve maximum control with the minimum amount of materials.
