How To Identify a Pavement Ant

Pavement ants have two nodes (bumps between middle and rear body sections). They are light to dark brown with fine grooves lining the head and thorax. Legs and antennae are lighter than the rest of the body. Workers are all one size. 

Where Do They Come From

Pavement ants produce small mounds at the entry of their nests. These nests are often located outdoors under stones, pavement cracks, wood, next to buildings and under building foundations. They can enter homes through cracks in the concrete; they will nest in the walls, under floors and around sinks. Pavement ants typically swarm in spring after a rain storm and they can swarm indoors.

How To Keep Ants Away

  • Trim back any shrubs or trees that come into contact with buildings. When plants touch a home or building they create an easy way for ants to crawl onto and access the building.
  • Seal all potential ant entryways. Common entry ways are around windows, doors, and utility lines.
  • Keep dry pet food in sealed bins and clean up any spills.

How To Get Rid Of Ants

  • Try to locate and destroy all nests by following ant trails from food source to the nest.
  • Use an insecticidal bait, especially during winter through early spring with populations are small.
  • Controlling these ants is hard, so consider hiring a pest management professional to help.
