Anywhere you have an old industrial river, century-old masonry and a lot of buildings packed together, you have rats. Paterson fits the description. The Passaic and its raceways, storm sewers beneath the streets, and many alleys and backyards where garbage is stored all provide cover and food. In winter, mice and rats move into basements, ground-floor kitchens and wall cavities to get warm.
If you've seen droppings or heard scratching, call (844) 725-1661. PestMinistry connects Paterson residents with independent, licensed rodent control providers; we do not set traps ourselves.
Two main culprits
- Norway rats are thick-bodied, with blunt noses and tails shorter than their bodies. They dig burrows beside foundations, under steps and beneath concrete slabs, and fit through holes about the size of a quarter.
- House mice are smaller, nest inside buildings, and squeeze through gaps the width of a pencil.
Roof rats are less typical in northern New Jersey than in the South, though they are sometimes reported near ports and urban areas.
Where they get in
Older Paterson buildings offer a bounty of access points: stone or brick foundations with aging mortar, uncapped chimney flues, gaps where utility lines enter, cellar windows with missing screens, and loose boards in porches. Trash stored in torn bags or open bins behind multi-family houses draws rats to the yard. Restaurants and food stores near commercial corridors add to the supply. Properties near the river or the Great Falls Historic District have steady pressure because of the cover and water.
Signs of activity
- Droppings: pellet-sized for mice, larger and blunt for rats.
- Burrow holes near foundations, fences, and under steps, with smooth, worn entrances.
- Greasy rub marks on pipes and baseboards.
- Gnawed food packaging, soap, wood and cables.
- Noises inside walls or ceilings at night.
What a licensed provider does
The work starts with identifying the species and locating entries, then reducing the population through traps and, where appropriate, tamper-resistant bait stations. Burrows are treated or filled once the animals are gone. The most important step is exclusion: steel mesh, concrete patching, metal door sweeps, and sealed utility openings. The technician may recommend changes to trash storage, since rats will stay around anywhere food is accessible. Follow-up visits confirm results.
Owner and tenant checklist
- Use metal or heavy plastic bins with tight lids for garbage and keep them off the ground if possible.
- Clean up spilled food and pet bowls in the evening.
- Close gaps beneath doors and around pipes.
- Cut back vines that climb walls to the roof.
- Do not stack boxes or wood against exterior walls.
Winter and spring timing
In Paterson, frozen ground and snow cover push rats toward basements and heated first-floor kitchens. Spring brings litters, so a small winter problem can double by May. If you spot fresh burrow soil after the thaw, call before the population grows. Cleaning up trash and sealing basement gaps in autumn is the most effective preventive habit for an old Paterson building.
Rodent questions in Paterson
Are rats dangerous in a city home?
They can contaminate food, damage wiring and carry diseases through urine and droppings, so prompt action is wise.
Is it my landlord's job to deal with rodents?
In many situations, yes, particularly for multi-unit buildings. Notify the landlord and document your request.
Why are there more rats after construction nearby?
Digging and demolition disturb burrows and push rats into neighboring properties.
Can I use poison from a hardware store?
Rodents can die in walls and cause odors, and poison can harm pets and wildlife. Professionals choose safer methods.
