Ant Control & Exterminator in Wantagh, NY
Brennan Termite & Pest Control eliminates ant infestations in Wantagh, NY at the colony level. Carpenter ants, pavement ants, and more. Family-owned since 1977. Call (516) 221-6329.
Every spring, the calls start. Ants appear along the kitchen counter, in the bathroom, near the sliding door to the back patio. Some Wantagh homeowners have dealt with the same entry points for three or four seasons in a row. They spray, the ants thin out, and a week or two later they are back. The pattern repeats because the colony was never addressed.
Ant colonies in Nassau County homes are not on the surface. They are inside wall voids, in structural wood, under concrete slabs, and in outdoor nests that may be well away from where the foragers appear inside your home. What you see on the counter represents a small fraction of the population. Until the nest is found and treated, the foragers you eliminate are simply replaced.
Brennan Termite & Pest Control is based in neighboring Seaford and has served Wantagh homeowners since 1977. Call (516) 221-6329 any time. Available 24/7.
Ants in Wantagh Homes: Why the Problem Persists
Wantagh’s housing stock is predominantly mid-century construction, with homes built in the 1950s through the 1970s on modest lots with established landscaping. That combination creates specific conditions for persistent ant problems.
Mature trees and landscaping provide woody debris, soil moisture, and direct pathways to the house. Wood framing that has weathered five or six decades may have soft spots near moisture entry points, particularly around windows, in crawl spaces, and in roof framing near gutters that have failed at some point. Carpenter ants are drawn to exactly these conditions. Pavement ants exploit the cracks and expansion joints that develop in aging concrete over time.
The result is that ant problems in Wantagh homes tend to recur predictably, and the same entry points and nesting sites appear season after season unless the source is treated.
Ant Species Brennan Treats in Wantagh
Identifying the species is the first step in any effective ant treatment. The species determines the nesting location, the risk level, and the correct treatment approach. Treating a carpenter ant infestation with a product formulated for pavement ants will not resolve it.
Carpenter Ants
Carpenter ants are the ant species of greatest concern in Wantagh homes. They are larger than other common household ants (half an inch to a full inch), typically black or dark brown, and most active at night. They excavate wood to create nesting galleries, preferring wood that has been softened by moisture. Common nesting sites in Wantagh homes include wood framing near failed or aging window seals, fascia boards behind moisture-holding gutters, structural members in crawl spaces, and decayed wood in deck posts or wood fencing.
One specific sign to watch for: small piles of coarse, sawdust-like material near baseboards, windowsills, or door frames. This is frass. It indicates active excavation. If you are seeing frass, the colony is established inside the structure.
Pavement Ants
Pavement ants are small, dark brown ants roughly 1/8 inch in length. They nest in soil under pavement, slabs, stoops, and patios, and they enter homes through expansion joints, foundation cracks, and gaps around utility penetrations at grade level. They do not cause structural damage, but their colonies are large and persistent. Brennan uses professional-grade products placed based on observed forager behavior, which reaches the colony more reliably than consumer bait products.
Odorous House Ants
Odorous house ants are small (about 1/8 inch), dark brown, and move in defined trails. They are named for the faint rotten smell they produce when crushed. They nest in wall voids, under flooring, and in insulation, drawn to moisture and sweet food sources. Their colonies can be multi-queen and large, which makes repellent spray treatments counterproductive. The colony fragments under chemical pressure, creating multiple smaller colonies. Brennan identifies whether a Wantagh home’s ant problem involves odorous house ants before selecting a treatment approach.
How Brennan Treats Ant Infestations in Wantagh
Most consumer ant products are repellents that create a chemical barrier foragers avoid. The ants seem to disappear, the colony is undisturbed, and when the barrier dissipates the ants return. For carpenter ants specifically, some repellent products trigger budding: the colony splits and establishes secondary nests in new locations. A homeowner who sprays a carpenter ant trail and then notices ants appearing elsewhere may have inadvertently caused the infestation to spread.
Brennan’s approach: Species confirmation is the foundation. Forager trail tracking locates entry points and the likely nest. Targeted treatment applies products at the nest site and along forager routes — the goal is colony elimination, not surface reduction. Full explanation before leaving and a free return visit if follow-up is needed.
What Wantagh Homeowners Should Know About Ant Season
On Long Island, carpenter ant foraging activity increases significantly from late March through June as temperatures rise. This is when most Wantagh homeowners first notice indoor ant activity. It is also the period when swarmers (winged reproductive ants) may appear indoors, which is a sign of an established colony.
Seeing swarmers indoors in spring is worth taking seriously. It typically means the colony has been established for a year or more and has grown large enough to produce reproductive adults. If you see winged ants indoors in spring, save one and call Brennan. The technician can confirm whether it is a carpenter ant swarmer, a termite swarmer, or a different species. Do not spray them.
Carpenter ant colonies are active in Nassau County from roughly late March through October, but infestations established inside a structure can be treated year-round. If you are seeing ants indoors in winter, the colony is inside the home, not outside it.

Frequently Asked Questions
Carpenter ants are noticeably larger than pavement ants or odorous house ants, typically ranging from half an inch to a full inch. They are usually black or dark brown. If you are seeing large ants inside your home, particularly in spring or near wood structures, it is worth having them identified. Brennan can confirm the species and advise whether treatment is warranted during a free inspection.
Both are possible. Pavement ants entering through a foundation crack may forage in the kitchen and return to an outdoor nest each time. A carpenter ant satellite colony inside a wall void near the kitchen may send foragers to the same location. The difference matters because treatment is different in each case. Brennan can identify which situation you have.
Carpenter ant colonies are active in Nassau County from roughly late March through October, with peak foraging activity in spring. Treatment during active foraging season is generally most effective. However, carpenter ant infestations established inside a structure can be treated year-round. If you are seeing ants indoors in winter, the colony is inside the home, not outside it.
Yes. Free inspections are available for Wantagh homeowners. Call (516) 221-6329 or request one online.
Do not spray them. Save one if possible and call Brennan. Winged ants in spring can be carpenter ant swarmers or termite swarmers, and they require different responses. Spraying kills the swarmers but does not address the underlying colony and may make a professional inspection less informative.
Typically no. Most homeowner’s insurance policies exclude damage caused by insects, including carpenter ants. Damage found during a real estate inspection may need to be remediated before closing. Brennan handles carpenter ant treatment for both active infestations and real estate inspection findings.
