Ant Control & Exterminator in Seaford, NY
Brennan Termite & Pest Control eliminates ant infestations in Seaford, NY at the source. Family-owned and based here since 1977.
The ants came back. You sprayed last week (or the week before) and they disappeared for a few days. Then they were back along the baseboard, or under the kitchen sink, or trailing up through a gap near the window frame. The spray worked on what you could see. It did not work on what you could not.
That is not a product failure. It is a problem of where the treatment went. Ant colonies in Nassau County homes live inside walls, under floors, in structural framing, and in outdoor nests that may be 20 feet from where you see foragers on the counter. Until the colony is located and treated at the source, the ants you are killing are being replaced faster than you can manage them.
Brennan Termite & Pest Control is headquartered in Seaford at 2085 Paddock Rd. We have treated ant infestations in Nassau County homes since 1977. Our technicians identify the ant species in your home, locate the colony, and treat the infestation where it lives: not where it shows up.

Why Ants Keep Coming Back After Treatment
The ants visible in your home are foragers: workers sent out from the colony to find food and water. In a healthy colony, foragers represent a small fraction of the total population. When you eliminate the foragers with a surface spray, the colony registers the loss and sends replacements. This cycle continues indefinitely unless something breaks it at the source.
There is a second problem with many consumer ant products. Repellent sprays create a chemical barrier that foragers learn to route around. Over repeated applications, the barrier becomes less effective as the colony adapts. Some products are specifically counterproductive for certain ant species, particularly carpenter ants, which can split a colony (a process called budding) in response to perceived threats, making a manageable problem into two separate infestations in different parts of the home.
Effective ant control in a Seaford home requires identifying the ant species, locating the nest, and applying treatment in a way that reaches the colony. That is not something a can of spray accomplishes. It requires a trained technician who knows what they are looking for and where to look.
Ant Species Common to Seaford, NY Homes
Not all ant problems are the same. The species determines the risk, the nesting location, and the correct treatment approach. Misidentifying the ant is one of the most common reasons DIY treatments fail and why some pest control treatments need to be repeated.
Carpenter Ants
Carpenter ants are the species that cause structural damage in Nassau County homes, and Seaford homeowners encounter them regularly. They do not eat wood; they excavate it to create smooth-walled galleries for nesting. Their preferred nesting sites are wood with elevated moisture content: window frames with water intrusion, fascia boards behind gutters, structural members in a crawl space or near a roof valley, or decayed wood in a deck or fence post.
Signs of a carpenter ant infestation include larger-than-usual ants (0.5 to 1 inch) appearing indoors, particularly in kitchens, bathrooms, and along baseboards; small piles of sawdust-like material (frass) beneath wooden structures or on windowsills; faint rustling sounds inside walls, most noticeable at night; and swarmers (winged carpenter ants) appearing indoors in spring, often near windows.
A single carpenter ant in the kitchen is not necessarily an emergency. Twenty of them along the same baseboard over several days usually indicates a satellite colony established inside the home, and a parent colony somewhere outdoors. Brennan technicians trace the foraging trail, locate the nest, and treat the infestation at both points.
Pavement Ants
Pavement ants are smaller than carpenter ants (about 1/8 inch) and they nest in soil beneath pavement, slabs, and concrete stoops. They enter homes through expansion joints, cracks in the foundation, and gaps at the base of exterior walls. Inside, they forage for sweets, grease, and protein and are commonly found in kitchens, pantries, and along the edges of floors.
Pavement ants do not damage wood, but their colonies can be large (upwards of several thousand workers) and persistent. Surface treatment provides temporary reduction. Colony treatment, reached through baiting or direct nest treatment, is what resolves the infestation.
Odorous House Ants
Odorous house ants (named for the rotten coconut smell they emit when crushed) nest in wall voids, under floors, and in insulation. They are small, dark brown, and move in well-defined trails. They are attracted to sugars and sweet foods. Like pavement ants, they respond poorly to repellent sprays alone because their colonies are large, multi-queen, and capable of splitting in response to chemical pressure.
How Brennan Treats Ant Infestations in Seaford
Step 1: Identification. The technician identifies the ant species. This determines whether structural damage is a concern, where the nest is likely located, and which treatment method will reach the colony without causing it to split or relocate.
Step 2: Trail and nest location. Forager trails are followed to identify where ants are entering the home and where they are going. For carpenter ants specifically, the technician looks for moisture sources and damaged wood that indicate where a satellite colony may be established.
Step 3: Treatment at the source. Depending on the species and nest location, treatment may involve targeted application to the nest site, non-repellent product application along forager trails, or bait placement that workers carry back to the colony. The goal is colony elimination, not surface reduction.
Step 4: Explanation. Brennan technicians explain what was found, what was applied, and what the homeowner should watch for in the days following treatment. This is part of every visit.
Step 5: Free return visit if needed. If the infestation is not fully resolved after treatment, Brennan comes back at no additional charge.
Ant Problems Seaford Homeowners Commonly Describe
“I spray and they go away, then come back in a week.” This is the colony replacement cycle. The nest was not reached by the treatment. Brennan locates the nest.
“I found sawdust near the baseboard and I don’t know where it came from.” This is carpenter ant frass. It indicates active excavation inside wood: the colony is established in the structure. This warrants immediate inspection.
“There are ants in my bathroom but I can’t figure out where they’re coming from.” Bathrooms are moisture sources. Carpenter ants are frequently found trailing to bathrooms through wall voids from a nest in adjacent framing. The entry point is not visible to the homeowner.
“I’ve been dealing with ants every spring for three years.” Annual recurrence typically indicates an outdoor parent colony that reactivates each season and re-establishes foraging routes into the home. Treating the indoor activity alone will not break the cycle.
“I tried bait stations from the hardware store and they didn’t work.” Consumer bait products are often the wrong formulation for the species present, placed incorrectly, or placed in locations where foragers are not actively trailing. Brennan uses professional-grade products placed correctly based on observed forager behavior.
