Seaford, NY Exterminators & Pest Control Services

You found something in your home. Whatever it was, a can of spray from the hardware store did not fix it — or you would not be here. Brennan is available 24/7 at (516) 221-6329.

You found something in your home. Maybe it was a trail of ants crossing the kitchen counter for the third time this month. Maybe it was droppings behind the refrigerator, or a wasp nest forming under the eave above your front door. Whatever it was, you already know a can of spray from the hardware store did not fix it — or you would not be here.

Brennan Termite & Pest Control is headquartered in Seaford at 2085 Paddock Rd. We have been protecting Nassau County homes from termites, ants, rodents, bees, wasps, and seasonal pests since 1977. That is nearly 50 years of solving pest problems in the same neighborhoods where we live and work. If you have a pest problem in Seaford, we have seen it before.

Common Pest Problems in Seaford, NY

Seaford sits in the Town of Hempstead in Nassau County, on Long Island’s South Shore. The housing stock here is predominantly single-family homes built between the 1940s and 1980s — the kind of construction that termites, carpenter ants, and rodents have had decades to learn how to enter. Seasonal patterns along the South Shore drive pest activity in predictable cycles. Brennan technicians know those cycles because they service these streets year-round.

Termites

Subterranean termites are common across Nassau County, and Seaford is no exception. The problem with termites is that they work silently. By the time a homeowner notices soft wood, bubbling paint, or a swarm of winged insects near a window, the colony has often been active for years. A professional inspection is the only way to know what is actually happening inside the structural wood of your home.

Brennan technicians locate termite activity at the source, treat it correctly, and explain exactly what was found and what was done. Learn about our termite control service

Ants

Carpenter ants are among the most common callbacks Seaford homeowners make after buying a store product. The spray kills what is visible on the surface. The colony — which may be living inside a wall void, under the subfloor, or in a structural beam — remains untouched. Pavement ants and other species are a nuisance; carpenter ants cause structural damage. Knowing which ant you are dealing with changes how it needs to be treated.

Brennan treats the colony, not just the foragers you can see. See our ant extermination service

Rodents

Mice and rats enter Nassau County homes most aggressively in fall as temperatures drop — but once they are inside, they stay through spring. They chew wiring, contaminate food, and breed faster than traps alone can manage. The entry points that let them in need to be found and closed, or the problem keeps returning.

Brennan technicians identify how rodents are getting in, treat the active infestation, and advise on exclusion. Learn about rodent control

Bees, Wasps, Yellowjackets, and Hornets

Wasp and yellowjacket nests hidden in eaves, siding, or underground are a genuine safety concern — especially if anyone in your household has a bee allergy. Brennan treats nests at night when the colony is inactive, which is more effective and reduces the risk to both the technician and your family. Carpenter bees bore into wood trim and decking and cause cumulative structural damage if left untreated.

Seasonal and General Pest Control

Cave crickets show up in Seaford basements every fall. Centipedes, ground beetles, and spiders follow seasonal patterns tied to Long Island’s weather. If you are seeing pests indoors that you cannot identify, a Brennan technician will identify them, explain what they are, and treat them correctly. See our seasonal pest control services

Why Seaford Homeowners Call Brennan

We are based here

Our office is at 2085 Paddock Rd. in Seaford. When you call, you are calling a team that knows this zip code, not a regional dispatch center.

The same technician, not a different face every time

Customers across our reviews mention technician Mike by name -- across visits stretching years apart. That kind of continuity is not something a national franchise can offer. The technician who comes to your home learns your property.

As Michael Brennan puts it: "Spraying the home with a can of pesticide is only a band-aid." Brennan technicians locate where the infestation is living, treat it at the root, and explain every step.

No recurring contracts

Brennan does not push monthly or quarterly spray programs. When there is a pest problem, we treat it. When it is resolved, we are done -- until you need us again.

Free return visits

If a treatment needs follow-up, we come back at no additional charge.

Unbranded vehicles

Our trucks carry no company markings. Your neighbors will not know we were there.

Certified and verified

Brennan holds active certification through the National Pest Management Professionals Association (NPMPA) with a Customer Trust Score of 94. We carry a 5.0 rating across Google (83 reviews), Yelp (40 reviews), and Angi (7 verified reviews). Zero complaints on file with the BBB.

Termite Treatment for Seaford Home Sales

If you are selling a home in Seaford and your buyer’s home inspector or engineer flagged termites or carpenter ants, you need two things before the sale can close: a professional treatment and a one-year written guarantee. Many sellers discover mid-transaction that not every pest control company provides the specific guarantee document lenders and attorneys require.

Brennan performs the treatment and issues the one-year written home-sale guarantee so your closing can proceed on schedule. Learn about our termite treatment and home-sale guarantee

First time customer - I called Mike Brennan after being referred by my family member. He answered my call, evaluated the situation, gave me some incredibly helpful tips to address the immediate issue, and fit me in after his last appointment on the same day. Mike and his associate (also Mike) arrived when they estimated, inspected the problem area, got to work, eliminated the problem and sealed the area all within an hour. The job was foul and they got pretty dirty, but they maintained their professionalism throughout. It’s doubtful you’ll find a more professional team in the area. Though I hope I will not need this particular service ever again, I would not hesitate to call them should the need arise. Thank you Mike and Mike!

Excellent service from start to finish. He was professional, punctual, honest, and extremely knowledgeable about termite treatment. From the initial inspection, he took the time to explain everything in detail with great patience, helping us understand exactly what was happening in our home, where the termites were likely coming from, and the best way to treat the problem. Thanks to his expertise, he correctly identified the source and created a detailed, effective treatment plan focused on the affected areas and around the home. He and his team completed the work efficiently and respectfully. It’s rare to find someone so trustworthy, dedicated, and clearly passionate about what they do. I highly recommend their service.

Mike is awesome! Really such an absolute pleasure to deal with. Randomly found him searching online (was looking for a truly family owner and operated business) and he didnt disappoint. We had an earwig infestation. I called Mike and he is probably one of the most patient human beings I have met. He spent time discussing the issue and the treatment. There was absolutely no pressure to use him. We ended up using him and he came and again explained everything he was doing.. he was extremely thorough and it's a month and half later and we are still bug free.
