Ant Control Guide for Long Island and Queens: Identification & Solutions

Ants in Your Long Island or Queens Home? Here's What to Do

Ants are the number one pest complaint across Suffolk County, Nassau County, and Queens every spring and summer. They're persistent, they find food sources you didn't know existed, and over-the-counter sprays typically make the problem worse by scattering colonies rather than eliminating them.

The good news: with the right identification and treatment approach, ant infestations can be fully resolved. Here's a complete guide for homeowners from Huntington to Flushing.

The Most Common Ant Species in Our Service Area

Pavement Ants are the small (1/8 inch), dark-brown ants you see in trails along sidewalks, driveways, and kitchen baseboards. They're the most common species in Queens neighborhoods like Astoria, Ridgewood, and Jackson Heights, as well as Nassau County communities like Garden City and Hempstead. Colonies live under slabs, sidewalks, and foundations. They enter homes through the smallest cracks seeking food and moisture.

Carpenter Ants are much larger (1/4 to 1/2 inch), black or black-and-red, and a serious structural concern. Unlike termites, they don't eat wood — they excavate it to create galleries for nesting. Homeowners in wooded Suffolk County areas like Huntington, Smithtown, Commack, and Hauppauge are most at risk. Carpenter ants prefer moist, damaged wood, so they're often a sign of an underlying moisture problem.

Odorous House Ants are tiny (1/16 inch) and dark brown, and produce a rotten-coconut smell when crushed. They're extremely common indoors, particularly in kitchens, and form massive super-colonies that are notoriously difficult to eliminate with sprays.

Argentine Ants are an invasive species common in Queens and western Nassau County. They form super-colonies spanning multiple properties and structures, making neighborhood-level treatment more effective than single-home approaches.

Why Spraying Ants Makes It Worse

When you spray visible ant trails with store-bought pesticides, you may kill the workers you see — but you trigger a defense response in the colony. Many ant species "bud," splitting into multiple sub-colonies when they detect a chemical threat. What was one nest becomes five. This is especially common with odorous house ants and Argentine ants.

Professional treatment uses non-repellent insecticides and targeted baits that foraging workers carry back to the queen without detecting them as a threat.

Finding the Nest: The Key to Elimination

Surface treatment alone never eliminates an ant infestation. The colony — and the queen — must be targeted. Finding the nest requires:

• Following trails backward — ants follow pheromone paths; trace the trail from your kitchen to its origin

• Inspecting moisture areas — most indoor colonies are near water: under sinks, around dishwashers, near leaking pipes

• Checking wall voids and insulation — carpenter ants and odorous house ants commonly nest inside walls near moisture sources

• Looking outdoors — many infestations originate from outdoor colonies entering through the foundation

Prevention for Long Island and Queens Homes

- Seal gaps in your foundation and around utility penetrations

- Store food (including pet food) in sealed containers

- Fix leaky pipes and faucets immediately — even small drips attract ants

- Keep tree branches trimmed away from your home

- Remove dead wood and leaf debris from around your foundation

- Don't leave dirty dishes overnight
