Spring in Newark brings a familiar sight: little mounds of sand along sidewalk cracks and a trail of tiny ants heading for the kitchen. In a city with so much concrete, brick and old timber, ants find homes of their own in places people rarely notice.
Three ants that matter in Newark
Pavement ants are the most visible. Dark brown to black with faint lines on the head, they nest under sidewalks, stoops, slabs and curbs and come indoors for grease and sweets. Odorous house ants are brown, form long trails, and give off a rotten-coconut smell when crushed. Their colonies split into many nests, often inside wall voids and behind baseboards. Carpenter ants are larger black or black-and-red ants that excavate soft, damp wood. They are the ones that can damage structure.
Where they come from here
Newark's older houses have wood porches, window sills and sheathing that suffer from chronic moisture, a recipe for carpenter ants. Trees along streets in the Forest Hill and Weequahic areas can deliver ants to rooflines when branches touch gutters. Pavement ants are everywhere the ground is paved, including the Ironbound's busy sidewalks. Ants in downtown high-rises usually travel through plumbing chases and trash rooms.
Reading the clues
- Fine sawdust piles (frass) with bits of insect parts near baseboards or window frames point to carpenter ants.
- Large, winged ants in late winter or spring inside the house may signal a nest within the building.
- Rustling sounds inside walls can be a carpenter ant colony at work.
- Persistent trails to sinks or pet bowls suggest a nearby moisture or food source.
How professionals approach it
The first step is identification, then tracking trails to nests or entry points. Treatments include baits for sweet-feeding species, non-repellent perimeter applications, and targeted treatments inside wall voids for carpenter ants. A pro will check roof flashing, porch columns, window sills, and bathroom or kitchen walls where leaks occur. Fixing moisture is part of the solution; otherwise carpenter ants return after the nest is treated.
For pavement ants nesting in sidewalks or patios, treatment often means placing bait near entrances and treating the foundation perimeter. Avoid spraying trails yourself, which can scatter colonies.
Rain and rapid temperature swings matter in the Northeast. After a soaking storm, carpenter ant colonies in saturated wood often send out foragers or relocate to drier parts of a building, and that is when many residents first notice them. A trail of large black ants in a kitchen at night is worth a closer look, because carpenter ants forage mostly after dark and a daytime check may miss them.
Steps for Newark homeowners and tenants
- Trim tree limbs and shrubs that touch the building.
- Replace rotted wood and seal gaps around windows and doors.
- Clean up spills and store sweet foods in sealed containers.
- Keep trash tightly covered and washed out regularly.
- Fix leaky roofs, gutters and plumbing quickly.

Ant FAQ for Newark
Why do I only see ants in the spring?
Warmer soils trigger colony growth and foraging. Winter activity continues inside heated buildings but is less visible.
Are carpenter ants as bad as termites?
They do not eat wood, but they hollow it out. Damage is usually slower than from termites, though still worth addressing.
Do I need to leave while ants are treated?
Usually not. Your provider will tell you any limited re-entry times.
How can I tell when treatment has worked?
Trails thin out over days and disappear. A brief increase near baits is normal.
