Ant Control for South Jersey Homes: Species, Solutions, and When to Call a Pro

The Ant Species Invading South Jersey Homes

Ants are the most common pest complaint in Gloucester County — and for good reason. South Jersey's warm summers, mild winters, and sandy soil create ideal ant habitat, and the region supports multiple species that each present different challenges. Spraying the ants you see in the kitchen does almost nothing because the colony producing those ants is somewhere else entirely — in the walls, under the slab, in the yard, or in a nearby tree.

Here's what's actually in your home and what professional treatment involves for each species.

Carpenter Ants: The Structural Threat

Carpenter ants are the largest ant species you'll encounter in Gloucester County — workers measure up to half an inch long, and they're typically black or dark brown. Unlike termites, they don't eat wood — they excavate it to create nesting galleries, pushing out piles of fine sawdust (frass) that are often the first sign of an infestation.

Where we find them in Gloucester County homes:

• Window frames and door frames with moisture damage
• Bathroom wall cavities where humidity from showers keeps wood damp
• Sill plates and band joists in basements with moisture issues
• Deck and porch framing in contact with soil
• Roof areas near gutter leaks or ice dam damage

The key to carpenter ant elimination is locating both the parent colony (usually in a tree, stump, or landscape timber on the property) and any satellite colonies inside the home. Treating only the indoor ants without finding the outdoor source colony means reinfestation within weeks.

Our treatment combines targeted gel bait inside the home, dust application in wall voids and galleries, and exterior perimeter treatment to eliminate the parent colony and prevent recolonization.

Odorous House Ants: The Kitchen Invaders

Small (1/8 inch), brown to dark brown ants that form trailing lines to food sources — particularly sweet or greasy foods. Named for the distinctive rotten coconut smell they emit when crushed. These are the ants most Gloucester County homeowners find marching across the kitchen counter.

Why DIY treatment makes them worse: Odorous house ants have multiple queens per colony and readily “bud” — splitting into new colonies when disturbed. Spraying them with over-the-counter insecticide kills the workers you see but causes the colony to fragment, creating multiple new colonies from one. This is why many homeowners report that their ant problem got worse after spraying.

The professional approach: Slow-acting gel bait placed along trailing routes. Workers carry bait back to the colony, share it through trophallaxis (food sharing), and the entire colony — including queens — is eliminated over 7–14 days. No spraying, no fragmentation, no escalation.

Pavement Ants: The Driveway Colonists

Small (1/8 inch), dark brown to black ants that build distinctive soil mounds in driveway cracks, sidewalk joints, and patio seams. They're ubiquitous throughout Gloucester County — every subdivision in Washington Township, Deptford, and Woodbury has them.

Pavement ants become a problem when colonies expand under slab foundations and find entry points into the home through expansion joints, plumbing penetrations, and foundation cracks. They're attracted to nearly anything edible — sweet foods, greasy foods, proteins, and crumbs.

Treatment: Exterior perimeter treatment combined with targeted bait at entry points. Pavement ants are less prone to budding than odorous house ants, so a combination of contact treatment and baiting is effective.

Pharaoh Ants: The Problem You Don't Want

Tiny (1/16 inch), yellowish ants that are uncommon in single-family homes but can be significant problems in apartment complexes, healthcare facilities, and commercial buildings in Gloucester County. Like odorous house ants, pharaoh ants bud aggressively when sprayed, making DIY treatment counterproductive.

Pharaoh ants require bait-only treatment — any contact insecticide causes colony fragmentation that makes the infestation dramatically worse. If you suspect pharaoh ants (very small, yellowish, often found near moisture in kitchens and bathrooms), call a professional before attempting any treatment.
