Pavement ants

Pavements ants are small and dark brown or black, although there may be reddish overtones present. About 3/16 of an inch. They sometimes show up in homes with concrete slab floors, in basements, or in garages. They typically nest under the concrete but sometimes push up piles of fine dirt. They do not damage wood, but severe infestations can undermine slabs and lead to cracks and settling.

On the exterior they are often found pushing up piles of fine dirt between garages and driveways, in the cracks of driveways, walkways, and garages, and especially in between pavers.

Pavement ant control

Pavement ant control generally involves a very thorough application of a professional quality non-repellent pesticide spray along the foundation, all sides of all exterior slabs, slab dividers, cracks in slabs, around pavers, bricks, or stone landscaping. This ant is very reactive to repellent sprays and using the wrong spray will just chase them around – and potentially into your living space!

Unfortunately, there really are no good non chemical pest prevention methods for Pavement ants. Some areas, such as Queen Anne, Magnolia, Wallingford, and scattered neighborhoods throughout the Greater Seattle area are just crawling with these ants. An ongoing service program to keep them from coming back is a solution that many of our customers have come to rely on.

Pavement ants will nest inside, look for food inside, and they will swarm inside homes. They will eat sweets, grease, and proteins, including pet food.
