Your Local Ant Control & Extermination Experts

Servicing Nassau County | Western Suffolk County

Seeing ants in your kitchen, bathroom, or along baseboards usually means there’s a nest nearby — not just a few strays. Sprays may kill what you see, but they don’t solve why ants keep coming back. The most effective way to get rid of ants is to locate the colony and treat it at the source—not just the ants you see. 

At EM Pest Control, we take a prevention-first approach. Our technicians identify entry points, nesting areas, and attractants so ant activity is stopped at the source — not just temporarily masked.

EM Pest Control provides professional ant extermination services across Nassau County and Western Suffolk County. We treat common local ant problems including carpenter ants, odorous house ants, and pavement ants by identifying the species, locating nesting activity, and tailoring treatment to the source of the infestation.

✔ Targeted treatment
✔ Long-term prevention
✔ Local technicians who understand Long Island homes and businesses

Common Ant Problems We Treat

Different ants behave differently — treatment should match the species.

Carpenter Ants: A Structural Warning Sign

Carpenter ants tunnel through wood to build nests, often targeting moisture-damaged areas like window frames, decks, and wall voids. Over time, this can lead to structural damage if not addressed.

Why it matters: Eliminating visible ants won’t remove hidden nests.

Odorous Ants: The Kitchen Invaders

Odorous house ants often nest inside wall voids, beneath floors, and near moisture sources. They spread quickly and release a strong odor when crushed.

Why it matters: DIY sprays usually make them spread.

Pavement Ants: Entering From the Foundation

 Pavement ants typically nest under sidewalks, slabs, and foundations. Once they find food or moisture, they move indoors and create persistent activity. 

Why it matters: Indoor treatment alone won’t reach the colony.

 Why Identification Matters

Treating the wrong species can push colonies deeper into the structure or cause ants to relocate. Different ants respond differently to baiting, non-repellent treatments, and exterior strategies. Misidentifying ants can make the problem worse and delay effective control.

Why Ants Keep Coming Back in Long Island Homes

Ant infestations on Long Island are often driven by a combination of moisture, food access, and structural entry points. Many homes have small foundation gaps, aging window frames, or landscaping that creates easy access.

Once a colony finds a reliable food or water source, it creates scent trails that other ants follow. Even if visible ants are eliminated, the colony continues producing more workers—leading to repeated activity in the same areas.

This is why surface treatments alone rarely solve the problem long-term.

How We Handle Ant Problems

  1. Inspection and Identification: We inspect the affected areas, identify the ant species, and look for nesting behavior, activity trails, and likely entry points.

  2. Targeted Colony Treatment: Depending on the species and conditions, treatment may involve baiting, non-repellent applications, or targeted treatment of active areas to address the colony at its source.

  3. Entry Point and Attractant Control: We look for the conditions drawing ants in, including moisture issues, food sources, and structural gaps.

  4. Prevention and Follow-Up: We provide recommendations and guidance to help prevent recurring activity after treatment.

This approach is designed to stop the cycle—not just reduce activity temporarily.
Ant activity often increases in the spring on Long Island as colonies expand and begin searching for food and moisture.

Signs of an Ant Infestation

Ant problems aren’t random. When ants find food, moisture, or an entry point, they establish scent trails and keep returning until the colony is addressed.

Same Spot, Same Time

Ants showing up in the same area daily often indicates an established trail—not random activity.

Coming From Cracks or Gaps

Ants emerging from tiny openings near windows, doors, or baseboards usually means a nearby nest or entry point.

Food + Moisture Hotspots

Kitchens, pantries, sinks, pet bowls, and trash areas are common activity zones once ants find a reliable source.

Worse After Rain or Heat

Weather shifts can push ants indoors—often revealing colonies that were already established outside.

Carpenter Ant Warning Signs

Soft wood, debris near trim, or faint rustling inside walls can point to carpenter ants and moisture issues.

What You Can Do to Prevent Ant Infestations

While these steps can help reduce ant activity, they typically don’t eliminate the colony. Most infestations require targeted treatment to fully resolve.

Seal Entry Points

We often find ants entering through tiny cracks around doors, windows, siding, and foundations. Sealing these gaps helps limit access.

Reduce Moisture

Ants are drawn to water sources. Fix leaks, wipe down damp areas, and keep sinks, basements, and crawl spaces as dry as possible.

Limit Food Access

Clean up crumbs, store food in sealed containers, and avoid leaving pet food out overnight. Trash should be sealed and emptied regularly.

Keep Exterior Areas Clear

Trim back vegetation touching the home and avoid piling mulch, firewood, or debris directly against the foundation.

Avoid Overusing Sprays Indoors

Spraying visible ants can disrupt trails and cause colonies to spread, often making the problem worse.

We called EM Pest Control when we had a mouse problem in our apartment. Eric and Devin came the very next next day and did a thorough inspection to find the entry points and close them up. They were professional, timely and easy to communicate with. They explained whole situation, as well as explained the solutions they used to get rid of and them keep them out. They also offer follow-up appointments to make sure the issue is taken care of.

I had a great experience with EM Pest Control, especially with Devon, who handled my service. He came by for preventative maintenance and addressed a small ant issue I was starting to notice. He also took care of a few carpenter bee spots outside I was concerned about. Devon was incredibly knowledgeable, explained everything clearly, and answered all my questions with patience. He was also just a pleasure to work with—friendly, professional, and thorough. I really appreciate the peace of mind and would absolutely recommend them!

Hello, I’ve used Eric Middleton for exterminating two of my properties. Eric takes his time educating us and communicates well about the pests that are invading our home and what he’s gonna do to treat them. He’s very patient with us and walks around the premises showing us where they may enter. Eric uses kid and pet friendly solutions, which is a plus. Overall, I’m very happy with the results and highly recommend.

Frequently Asked Questions

Professional ant treatment depends on the severity of the infestation, type of ant involved, and how long the problem has been active. After an inspection, we provide a clear recommendation based on your specific situation, focusing on long-term.

Ants primarily nest outdoors but will also nest indoors as well. Their favorite nesting sites vary with their species.

  • Carpenter ants prefer to nest in open sunny areas like parks, yards, and golf courses.

  • Odorous house ants prefer to nest in shallow soil beneath stones, boards, logs, mulch, and debris.

  • Pavement ants' nest in the damp soil next to sidewalks, driveways, foundations, and spaces in masonry walls.

As ants move around your yard searching for food and water sources or if the weather becomes too harsh, ants will move indoors through spaces they find in our home’s exterior. Once inside, they nest in wooden structures, walls voids, and insulation.

Yes. We use products applied in targeted areas and according to label guidelines. Our technicians explain what’s being used and where, so you know exactly what to expect.

Cleaning food sources, sealing entry points, and eliminating the colony are key. Surface sprays alone won’t stop ants from returning.

In many cases, ant activity usually decreases within a few days, but full elimination depends on colony size and location. Some situations require follow-up to fully resolve the problem.
