Pavement Ants
Tetramorium caespitum
Pavement ants are small, dark brown to black ants measuring about 1/8 inch in length with distinctive parallel grooves on their heads and thorax. These common household pests get their name from their habit of nesting under pavement, concrete slabs, and along sidewalks. Colonies can contain thousands of workers and multiple queens.
Habitat & Behavior
Pavement ants typically nest under sidewalks, driveways, patios, foundations, and concrete slabs where they can access soil. They create small dirt mounds between pavement cracks and along edges. When seeking warmth or moisture, they move indoors and nest in walls, insulation, and under floors. They're particularly attracted to kitchens and areas near heat sources.
Signs of Infestation
- Small piles of soil or sand along sidewalk edges and between pavement cracks
- Trails of ants moving along foundations, baseboards, and pavement edges
- Ants in kitchens foraging for greasy or sweet foods
- Swarmers (winged reproductive ants) appearing indoors in spring
- Groups of ants engaged in territorial battles on pavement surfaces
Health & Property Risks
Pavement ants are primarily nuisance pests that contaminate food and create unsightly dirt mounds on sidewalks and driveways. While they don't cause structural damage or transmit diseases, their persistent foraging behavior and large colony sizes make them difficult to control. They can sting when threatened, though stings are mild and rarely cause problems.
Prevention Tips
- Seal cracks in driveways, sidewalks, and foundation walls
- Store food in sealed containers and clean up crumbs promptly
- Eliminate moisture sources by fixing leaky pipes and improving drainage
- Keep mulch and vegetation at least 12 inches away from your foundation
- Regularly clean kitchen floors, counters, and areas behind appliances
- Install door sweeps and repair damaged weather stripping
Professional Treatment Approach
Greenix's pavement ant treatment combines exterior perimeter applications with crack and crevice treatments around foundations, sidewalks, and entry points. We use professional non-repellent insecticides that ants unknowingly transfer throughout their colony, eliminating the queen and workers. For severe infestations, we apply granular baits along foraging trails and treat nesting sites directly when accessible.

Other common ants you might encounter
Carpenter Ants
Carpenter ants are large, black or dark-colored ants measuring 1/4 to 1/2 inch in length. Unlike termites, they don't eat wood but excavate it to create nesting galleries, leaving behind piles of sawdust-like material called frass. These destructive pests are one of the most common wood-damaging insects in North America.
Fire Ants
Fire ants are small, aggressive red or reddish-brown ants measuring 1/8 to 1/4 inch long. They're known for their painful, burning stings that leave raised, white pustules on the skin. These invasive pests build distinctive dome-shaped mounds in lawns and open areas, with colonies containing up to 250,000 workers.
Sugar Ants (Odorous House Ants)
Sugar ants are small, dark brown to black ants measuring 1/16 to 1/8 inch in length. Often called odorous house ants, they emit a distinctive rotten coconut smell when crushed. These persistent pests are attracted to sweet substances and can quickly establish large colonies with multiple queens inside your home.
