Pavement Ant

Pavement Ants are dark brown to blackish in color and are about 1/8 inch long.

Habitat

Pavement ants get their name because they make their nests in or under cracks in pavement. Colonies are usually easy to find due to the piles of displaced soil next to and on top of pavement. Indoors, pavement ants nest in walls, insulation and under floors. They like to travel under the edges of carpet next to the tack strip.

Winged reproductive pavement ants typically swarm in the spring but have been known to emerge any time of the year in heated structures. It is not uncommon to see swarming in late fall and into February even in colder climates.

After emergence, the ants mate and the queens burrow into the soil to begin laying eggs. Worker ants develop over a two-to-three-month period.

Most colonies are located under sidewalks, building slabs, and large rocks. Ants enter buildings through cracks in foundation walls and interior slabs. It is common to see sand piles and small soil particles in structures near cracks in concrete slabs or at the top of foundation walls where the ants deposit debris from excavated nests. Similar piles are seen in the warmer months at the cracks in sidewalks. Indoors, pavement ants nest in walls, insulation and under floors. They like to travel under the edges of carpet next to the tack strip.

Diet

Pavement ants are opportunistic feeders that will “swarm”on foods that appear within their foraging range, and are therefore easily controlled with bait. Indoors, they feed on meats, nuts, cheese, honey, bread crumbs, meats, grease and pet bowls.

Control

Individual pavement ant colonies can often be controlled using ant baits, but perimeter inspection and treatment are usually necessary for long-term pavement ant control. Their colonies are controlled by direct treatment of nests in the soil.
