Rodent Control & Exterminating on Long Island

Q: What does your sanitation service include?

Our sanitation service covers removal of visible droppings and surface cleaning/disinfection in accessible areas (for example: basement floors, crawlspace surfaces, garage areas, and other reachable spots). If insulation is contaminated, it’s a separate remediation step. We can point you to a couple local companies' customers have used, or you can use your own contractor.

Is Your Property Infested with Rodents?

Servicing Nassau County | Western Suffolk County

Hearing scratching in the walls or seeing signs of mice or rats in your Long Island home or business? In most cases, there’s more activity hidden out of sight—and it won’t go away on its own. Rodents can contaminate surfaces, damage wiring, and create ongoing problems if the source isn’t addressed.

At EM Pest Control, we don’t just set traps and leave. We remove active rodents and identify how they’re getting in, sealing entry points to help prevent the problem from coming back and support long-term control.

How Do You Get Rid of Mice or Rats Permanently?

Getting rid of rodents isn’t just about removing what you see—it’s about stopping how they’re getting in and why they’re staying. Most infestations continue because entry points are left open, allowing new rodents to replace the ones that were removed.

Identify where rodents are entering the structure
Eliminate active rodent activity
Seal entry points to prevent re-entry
Address conditions that attract rodents
Monitor to ensure the problem is fully resolved

This is why trapping or baiting alone usually doesn’t solve the problem long-term. Without identifying and sealing entry points, rodent activity will continue or return.

Signs of a Rodent Infestation

If you're hearing scratching in the walls, finding droppings, or noticing damage around the home, there is usually more going on than a single mouse or rat. Rodent activity often builds quietly behind walls, in attics, garages, and storage areas before homeowners realize how established it is.

Scratching in walls or ceilings — often caused by rodents moving through wall voids or attic spaces
Droppings in kitchens, pantries, basements, or garages — one of the clearest signs of active rodent presence
Gnaw marks on wood, wires, insulation, or food packaging — rodents constantly chew to wear down their teeth
Musty or foul odors in enclosed areas — can point to nesting or hidden rodent activity
More activity at night — rodents are often most active after dark when the home is quiet

Rodent problems usually come down to access, food, and shelter—once rodents find a way in and a reason to stay, activity will continue until those entry points are addressed.

Is It Mice or Rats?

Mice and rats leave different signs, and proper identification matters because treatment can vary depending on the species involved.

Mice: Smaller droppings, scattered, more active inside walls and kitchens
Rats: Larger droppings, clustered, more destructive and concentrated
Both: Cause contamination, damage, and repeat problems if entry points remain open

Mouse Droppings

Size: Grain of rice (1/4")
Shape: Pointed ends
Location: Scattered in multiple areas

Rat Droppings

Size: Olive pit or bean (3/4")
Shape: Blunt / rounded ends
Location: Grouped in concentrated areas

Gnaw Marks & Damage

Rodent teeth never stop growing. Look for rough wood shavings, chewed wires, or shredded insulation near the floor, garage, or attic.

How Rodents Enter Your Home or Business

Mice and rats are opportunists that exploit small structural gaps to get inside. During an inspection, we look for the specific weak points that allow them to enter and re-enter.

The Low Ground: Foundation Vents

Primary Threats: Norway Rats, House Mice, Deer Mice

Rodents use damaged, loose, or unprotected foundation vents as easy access points into crawl spaces and lower areas of the structure. Once inside, they can move upward into walls, basements, and other concealed spaces.

Technician's Insight: "Standard insect screen isn't enough—rats and mice can chew right through it. We install heavy-gauge steel mesh (exclusion barriers) that allows airflow while helping block rodent entry."

Long-term rodent control depends on identifying and sealing these access points—not just removing the rodents that are already inside. For more on long-term protection, see our guide on rodent prevention for Long Island homes.

How We Handle Rodent Problems

Effective rodent control isn’t just about removing what you see—it’s about finding how they’re getting in and stopping it at the source. Our process is built to address both the current activity and the conditions that allow it to continue.

Inspection & Identification: We identify where rodents are active, where they’re nesting, and how they’re entering the structure.
Targeted Removal: We address active rodent activity using methods appropriate for the situation and environment.
Entry Point Sealing (Exclusion): We locate and seal accessible entry points to help prevent rodents from getting back inside.
Prevention & Monitoring: We recommend and implement steps to reduce conditions that attract rodents and monitor to ensure the problem is fully resolved.

Without addressing entry points, rodent problems often return—even after initial activity is reduced.

Pricing depends on the level of activity and the amount of exclusion work needed. Many homeowners choose plans that include sealing entry points to prevent repeat problems.

Absolutely. We prioritize the safety of your family and pets above all else. EM Pest Control utilizes strategic placement of professional tamper resistant bait stations called Bell Sensing IQ Bait Stations around the exterior of your home or business, in protected locations (like secured crawl spaces, or attics) where your child and pets can't access the bait inside. For indoor issues, we primarily rely on non-toxic trapping and exclusion (sealing) methods, which are completely safe for the living areas of your home.

We locate common rodent entry points and seal accessible gaps as part of the service. If we find areas that require carpentry or structural repair beyond pest-related sealing, we’ll point them out and recommend next steps.

Our sanitation service covers removal of visible droppings and surface cleaning/disinfection in accessible areas (for example: basement floors, crawlspace surfaces, garage areas, and other reachable spots). If insulation is contaminated, it’s a separate remediation step. We can point you to a couple local companies' customers have used, or you can use your own contractor.

While store-bought traps may catch a few individuals, they rarely solve the underlying problem. For example, steel wool does not stop rodents. Mice and rats will pull it out to gain access to your property and will deteriorate over time.

Our technicians use materials that does not deteriorate, and rodents will not be able to pull it out. Our technicians are trained to use those material and find hidden access points that DIY attempts often miss, providing a comprehensive, long-term solution rather than a temporary fix.

At EM Pest Control, we stand out due to our commitment to permanent, guaranteed results through our proven Exclusion program. We move beyond simple trapping by prioritizing sealing, removal, and sanitation. Our focus is on long-term prevention and peace of mind, ensuring your home or business is secure against future invasions, all backed by professional expertise and monitoring.
