Rodent Control in Suffolk, Nassau & Queens: How to Keep Mice and Rats Out

Mice and Rats on Long Island and Queens: A Growing Problem

Rodent pressure is one of the most persistent pest challenges facing homeowners and businesses across Suffolk County, Nassau County, and Queens. Whether you're in a single-family home in Smithtown, a condo in Great Neck, or a restaurant in Astoria, rodents are constantly looking for the same three things you have: food, water, and shelter.

Long Island's mix of dense residential neighborhoods, commercial corridors, and wooded preserves creates ideal conditions for both mice and rats. Understanding the difference between species — and what draws them to your property — is the first step toward keeping them out for good.

Two Species You'll Encounter Across Our Service Area

House Mice (Mus musculus) are the most common pest rodent across Suffolk and Nassau counties. They're small (3–4 inches body length), light brown to gray, and extraordinarily agile — able to squeeze through a gap the size of a dime. A single pair can produce 40–60 offspring per year. In suburban neighborhoods like Levittown, Hicksville, and Bay Shore, house mice move indoors in September and October seeking warmth and are often not discovered until winter is well underway.

Norway Rats (Rattus norvegicus) are larger, bolder, and primarily a concern in Queens neighborhoods like Jamaica, Jackson Heights, and Long Island City — as well as commercial areas throughout Nassau County. Norway rats burrow along foundations, under slabs, and in debris piles. They're strong gnawers capable of chewing through PVC pipes, electrical insulation, and even soft concrete.

Roof Rats (Rattus rattus) are less common but found in coastal communities like Long Beach, Freeport, and parts of Queens near the waterfront. They prefer higher areas — attics, roof spaces, and trees — and are excellent climbers.

Warning Signs of Rodent Activity

• Droppings — Mouse droppings are 1/4 inch, dark, and pointed at both ends. Rat droppings are larger (3/4 inch), dark, and blunt-ended. Fresh droppings are dark and moist; old droppings turn gray and crumble

• Gnaw marks — Look for chewed food packaging, gnaw marks on wood trim or drywall, and damaged wiring insulation

• Runways — Grease marks along walls and baseboards where rodents travel repeatedly

• Nests — Shredded paper, insulation, or fabric in hidden locations like drawer backs, wall voids, and attic insulation

• Sounds — Scratching or squeaking in walls or ceilings, particularly at night

• Tracks — In dusty or muddy areas, footprints and tail drag marks

Entry Points to Inspect and Seal

Rodent exclusion — sealing the ways they get in — is the most permanent solution. Focus on these areas:

• Foundation gaps — even hairline cracks should be sealed with hydraulic cement or caulk

• Utility penetrations — every pipe, cable, and conduit entering your home should be sealed with steel wool and caulk or metal flashing

• Garage doors — the bottom rubber seal deteriorates over time; replace it if mice can slide under

• Roof and attic vents — should be covered with 1/4 inch hardware cloth

• Weep holes in brick — common in older homes in Hempstead and Nassau County communities; use copper mesh

• HVAC and dryer vents — ensure covers are intact and close tightly
