Rats are a common concern for homeowners, landlords, and tenants across New York City. They can enter buildings in search of food, water, shelter, and safe places to move and nest.
So, how to keep rats out of NYC homes?
Start by removing easy food sources. Store garbage correctly. Reduce clutter. Repair leaks. Inspect the building for holes and gaps. Then seal suitable entry points with rodent-resistant materials. If rats are already active inside the property, trapping and professional treatment may also be needed.
NYC Health recommends this type of combined approach. The city advises property owners and residents to control garbage, remove shelter, and repair cracks and holes that allow rats into buildings. This guide explains how rats enter NYC properties, the warning signs to watch for, how to rat-proof your home, and when professional help makes sense.
Why Do Rats Enter NYC Homes?
Rats enter properties because they can find the basic things they need to survive.
Food is one of the biggest attractions. Open garbage, spilled food, pet food, and poorly stored food waste can provide an easy meal.
Water matters too. Leaks, standing water, and other moisture sources can support rodent activity.
Shelter is another factor. Basements, cluttered storage areas, yards, wall voids, and other protected spaces can give rats places to hide.
NYC Health explains that rats look for food, water, shelter, and safe travel routes. Garbage and clutter can provide both food and hiding areasUnderstanding these needs is the foundation of effective rat prevention NYC homeowners can use.
What Are the Signs of a Rat Infestation?
You may have rats without seeing a live animal.
Rats are often active when people are less active. Instead of waiting for a sighting, look for evidence around the property.
Common signs include fresh droppings, gnaw marks, greasy rub marks, worn travel paths, structural holes, and burrows. These are also among the active rat signs used by NYC Health inspectors. You may also hear movement inside walls or ceilings.
Repeated signs should not be ignored. They can indicate that rats have already found food, shelter, or access to the building.
Where Do Rats Hide in NYC Homes?
Rats prefer areas where they can remain protected.
Basements are a common concern because they may contain storage, utility openings, floor drains, pipes, and access to foundations.
Other possible areas include spaces behind appliances, utility rooms, garages, storage rooms, yards, and hidden structural voids.
Outdoor areas matter as well. Dense vegetation, clutter, exposed garbage, and burrows can support rats close to the building.
NYC Health advises residents to remove clutter and litter, keep stored items away from walls and off the ground, and manage weeds and shrubs around properties.If you are unsure which rodent is present, our Rat vs. Mouse: How to Tell the Difference guide can help you compare common signs.
How to Keep Rats Out of NYC Homes Step by Step
The strongest prevention plan does not depend on one trap or one treatment.
It combines food control, garbage management, building maintenance, exclusion, and monitoring.
Step 1: Remove Easy Food Sources
Start in the kitchen and food-storage areas.
Store food in tightly closed containers. Clean spills and crumbs. Avoid leaving pet food available overnight. Check underneath appliances where food can collect unnoticed.
Outdoor food sources also matter.
Do not leave food out for wildlife. Keep food waste properly contained until collection.
NYC Health states that rats need only a small amount of food and recommends keeping food in tightly sealed containers.This simple step can make the property much less attractive.
Step 2: Manage Garbage Correctly
Garbage control is one of the most important parts of NYC rat infestation prevention.
Use appropriate containers with tight-fitting lids. Avoid exposed food waste. Keep garbage areas clean and follow your building’s disposal rules.
NYC Health specifically recommends hard plastic, rat-resistant containers with tight-fitting lids and enough containers to hold the property’s garbage. Garbage control should continue even after rat activity disappears.
Step 3: Remove Clutter and Shelter
Rats need protected areas to hide and nest.
Clear unnecessary cardboard, paper bags, bottles, and other clutter from basements, storage spaces, and outdoor areas.
Where practical, keep stored items off the floor and away from walls.
Outside, trim vegetation and remove conditions that can provide protected hiding areas.
This makes it easier to inspect the property and notice fresh signs of rodent activity.
Step 4: Check the Building for Entry Points
If you want to know how to prevent rats in NYC, inspect the structure as carefully as the kitchen.
Look around foundations, doors, windows, vents, pipes, utility penetrations, basement walls, floors, and other openings.
NYC Health recommends checking foundations, sidewalks, and spaces under doors for cracks or holes and repairing them. Do not assume that a hole is too small to matter.
Step 5: Seal Rat Entry Points Correctly
Knowing how to seal entry points for rats is essential because weak repairs may fail.
For small cracks and holes, NYC’s current guidance recommends durable construction-grade materials rather than inexpensive caulk intended only for minor repairs. Door gaps can be addressed with rodent-resistant metal sweeps. Vents and some larger openings may require screens, metal, hardware cloth, mortar, or other suitable materials depending on the structure. Large structural openings may need professional repair.
This process is commonly called rat proofing NYC properties.
What Is Rodent Proofing?
Rodent proofing means making it harder for rats and mice to enter and move through a property.
It goes beyond putting traps in a basement.
A proper inspection may include doors, foundations, vents, windows, pipe openings, utility penetrations, wall gaps, floors, and other vulnerable areas.
Effective rodent proofing NYC also considers the material used for each repair. A weak patch may be damaged or reopened.
Our Rodent Proofing Tips for NY guide explains additional ways to strengthen vulnerable areas.

How to Keep Rats Out of Your Home After Exclusion
Sealing openings is important, but it should not be the only step.
The how to keep rats out of your home strategy works best when exclusion is combined with sanitation and monitoring.
Continue controlling garbage. Keep food protected. Repair leaks. Reduce clutter. Check previously active areas for new droppings or gnaw marks.
Also inspect repairs from time to time.
New building damage or utility work can create another opening.
Long-term prevention is an ongoing process, especially in dense urban environments where rodent activity may involve more than one property. NYC Health notes that rats rarely exist on only a single property and can require a neighborhood-level response. Our guide on Why Rats Thrive in NYC explains the urban conditions that can support rodent activity.
How to Keep Rats Out of an Apartment in NYC
Apartment residents face a different challenge.
The source may not be limited to one unit.
Rats can use structural openings and connected building areas. That means cleaning one apartment may not solve a building-level problem.
To keep rats out of apartments, NYC residents should store food securely, manage garbage, report leaks, reduce clutter, and report holes or other building defects to management.
If you want to prevent rats in apartment buildings over the long term, communication with the landlord or property manager can be important.
NYC Health says tenants should promptly report rat activity to property owners, building managers, or co-op associations. Property owners are required to keep properties rat-free and address conditions that can lead to rat problems. For apartment and multifamily concerns, see our guide to Rodents in NYC Buildings.
What Should NYC Tenants Do If They Find Rats?
Document what you find.
Take note of droppings, holes, gnaw marks, or other activity. Report the problem to your landlord, superintendent, property manager, or co-op association.
Also report structural conditions that may be contributing to the problem.
NYC Health states that property owners are required to keep properties rat-free and address conditions that can lead to rats. If an owner does not address the problem, tenants can report it through 311. This is especially important when the source is outside the tenant’s control.
Do DIY Rat Traps Work?
Traps can play a role in rodent control, but they do not fix every cause of an infestation.
Catching one rat does not close a hole in a foundation. It does not remove exposed garbage. It does not repair a damaged door or eliminate a hidden food source.
This is why effective rodent control NYC should address both the animals and the conditions supporting them.
If you use traps, follow the product instructions carefully and keep them away from children and pets as appropriate.
Rodenticides require even more caution. NYC Health says effective rat poisons should be applied by a New York State-licensed pest management professional, and commercial and multi-unit property owners are required to hire a pest management professional for this work.
Why Do Rats Keep Coming Back?
Recurring rat activity usually means that at least one supporting condition remains.
There may still be an entry point. Garbage may be accessible. Outdoor burrows may remain active. Rats may be moving from nearby properties.
This is why simply killing visible rats may provide only temporary relief.
The better approach is to ask four questions:
Where are they entering? What are they eating? Where are they hiding? What route are they using?
Those answers help determine the next step.

When Does a Rat Problem Need Professional Help?
Professional help makes sense when signs continue despite sanitation and exclusion work.
It is also worth calling an expert when rats are active in several parts of the property, you cannot locate entry points, structural repairs are needed, or rodent activity continues after DIY trapping.
A rat exterminator NYC property owners hire should inspect before recommending a treatment plan.
NYC Health’s guidance for pest management professionals says inspections should occur before a quote is given and that treatment plans should be based on inspection findings. The agency also notes that moderate-to-severe infestations can require repeated visits. This is why professional rat control NYC should be viewed as a process rather than a single treatment.
What Does Professional Rat Control Include?
The exact service depends on the property and infestation.
An inspection comes first. A technician can look for droppings, rub marks, gnawing, holes, burrows, food sources, and travel routes.
A treatment plan may then involve trapping, secured bait stations where appropriate, monitoring, sanitation recommendations, and exclusion work.
The goal of pest control for rats NYC should be to reduce current activity while also addressing the reasons rats entered.
Some properties require follow-up visits to check progress and adjust the plan.

Why Prevention Is Better Than Waiting for an Infestation
Rat problems can become harder to manage when the conditions supporting them remain unchanged.
Early prevention gives you more control.
A secured garbage area is easier to manage than an established feeding site. Repairing an opening before rats begin using it is better than discovering activity inside the building later.
Regular inspections can also reveal fresh damage.
