Rodent Control in New Brunswick, NJ
Trapping, entry-point sealing and follow-up monitoring for New Brunswick homes and businesses. Free inspection, written quote.
Exclusion, Not Just Trapping
Trapping removes what is there. Sealing at 6mm decides whether more arrive. Every job includes the entry points, not just the traps.
Sewer Lateral Checks
Rats travel sewer mains and surface through broken laterals and dried floor drain traps. It is the route almost nobody checks in New Brunswick.
No Bait Inside Occupied Homes
Rodenticide indoors means animals dying in wall voids you cannot reach. We trap inside and keep bait outside in tamper-resistant stations.

House Mouse or Norway Rat — Telling Them Apart
Getting the species right changes the whole job, and here the answer is nearly always one of two animals.
House mouse (Mus musculus). Droppings 3 to 6mm, dark, pointed at both ends. Squeezes through a gap the width of a pencil — about 6mm. Nests in insulation and wall voids and rarely travels more than about 10 metres from the nest. Light scratching sounds just after dark.
Norway rat (Rattus norvegicus). Droppings 18 to 20mm with blunt ends. Gets through a gap of about 13mm. Burrows, swims, travels sewer lines, ranges 30 to 50 metres or more. Heavier sounds — gnawing, dragging, thumping.
Roof rats are genuinely rare here. If a company tells you that you have roof rats in this part of the state, ask what they based it on — roof rat control is an above-ground job and Norway rat control is a below-ground one.
Grease trails — dark smears along skirting, joists and pipe runs where fur oils rub off on a route used repeatedly — tell you where the animals actually travel, which is where traps go. Gnaw marks run about 2mm wide for mice, 4mm for rats.
How They Get In and Why They Stay
Two numbers do most of the work: 6mm for a mouse, 13mm for a rat. In older attached housing there are usually more such gaps than anyone expects.
- Riser and utility penetrations. The annular gap around pipes passing through walls and floors is usually open because the escutcheon plate is missing — a vertical route from cellar to roof.
- The sewer lateral. The one almost nobody checks. Rats surface through broken laterals, dried floor drain traps and unsealed clean-outs. If rats appear inside with no visible exterior entry, a camera inspection of the line settles it.
- Balloon-framed wall cavities, running uninterrupted from sill plate to attic — so a mouse entering at grade is heard on the top floor, and treating where the noise is accomplishes nothing.
- Door sweeps, cellar entries, areaway doors, dryer vents and air-conditioner sleeves with failed or missing seals.
They stay for food, water and harborage — and in dense housing the food is very often not inside your unit at all, but kerbside refuse on the block or a restaurant's rear yard.
Trapping, Baiting and Exclusion — What Order and Why
Exclusion is the only permanent step. Everything else manages the population. A company quoting trapping and baiting with no exclusion is selling you a subscription.
Inside an occupied building: trap, do not bait. Rodenticide indoors means an animal dying inside a wall void you cannot reach, smelling for weeks. Interior work is snap and multi-catch traps against walls, on grease trails, at right angles to the run — two traps for an established population is theatre; twelve is a treatment.
Outside: burrows and harborage. Exterior treatment goes in tamper-resistant stations placed on active burrows and runs rather than spaced decoratively along a fence line. Collapsing burrows afterwards tells you whether they reopen, which tells you whether you have solved it.
What is in the bait. Second-generation anticoagulants — brodifacoum, bromadiolone, difethialone, difenacoum — were removed from general consumer sale by the EPA's rodenticide risk mitigation decision and restricted to professional use in tamper-resistant stations. That is why the products left on the hardware shop shelf are the weak ones, and much of why do-it-yourself rat control fails. It also matters for secondary poisoning: a rodent carrying these stays toxic to whatever eats it — hawks, owls, cats, dogs. Bromethalin is a neurotoxin rather than an anticoagulant, acts faster and has no antidote. Ask which class is being used and where it is going.
Sealing materials. Copper mesh, hardware cloth and mortar work. Steel wool rusts out within a season, and expanding foam alone gets chewed straight through — it only works over a metal backing.
Rodents in Apartments and Restaurants — and What They Cost You
In attached and stacked housing the building is the unit, not the apartment — a treated apartment between two untreated ones is reseeded within weeks.
If you rent in New Jersey, a rodent infestation is a habitability and property maintenance condition and correcting it is the owner's responsibility. Report it to the landlord in writing and keep the copy. If the building has five or more units it is registered under the Hotel and Multiple Dwelling Law and inspected on a cycle by the New Jersey Department of Community Affairs, Bureau of Housing Inspection — a state route alongside your municipal health department. A documented complaint that was ignored is what turns a routine inspection into a finding.
What it costs you. Mouse urinary protein is a recognised indoor allergen and a documented asthma trigger, and in dense older housing the exposure is continuous — worth putting in those terms in writing to a landlord. Rodents also gnaw constantly to wear down growing incisors, and chewed wiring inside a wall void is a real fire risk.
Rodent Control — Common Questions
How long does it take?
A contained mouse problem in a single unit is usually two to four weeks across two or three visits. For an established rat population, or mice in a multi-family building where the neighbours are untreated, plan on six to twelve weeks — and expect the timeline to depend on how much exclusion gets done.
What about my dog or cat?
Tell us before the visit. Interior work should be trapping rather than bait precisely so there is nothing toxic for a pet to reach, and exterior bait goes in tamper-resistant stations secured to the ground. If a neighbour is baiting, be aware of secondary poisoning — a pet that catches a poisoned rodent is exposed to the rodenticide too.
Why do I still hear them after treatment?
Usually one of three things: the entry point has not been sealed and new animals are still arriving; the noise is in a shared wall void fed from a neighbouring unit; or it is not rodents at all — squirrels are active at dawn and dusk rather than after dark, which is the quickest way to tell them apart.
Pest Pressure in New Brunswick, NJ
New Brunswick is a dense small city built around two things that shape its pest work more than geography does: Rutgers University and a major hospital complex. The student population turns over comprehensively every year, and turnover is the single largest driver of bed bug introduction anywhere. The hospital and its associated institutional food service operate around the clock.
The Raritan River runs along the southern edge and the low ground beside it holds water and floods; the Delaware and Raritan Canal follows the same line. The Northeast Corridor rail line cuts through the middle with the ballast, embankment and fenceline harborage that comes with it.
The city divides sharply. Downtown and the Hub City blocks carry dense mixed-use — commercial kitchens on the ground floor with apartments above, which is one of the most reliable sources of building-wide roach populations there is. The College Avenue and Easton Avenue corridors are wall-to-wall student rentals in older housing. The Fifth Ward, Esperanza and the streets toward the Highland Park border are dense residential. Older sections drain into combined sewers that surcharge in heavy rain.

What New Brunswick Buildings Are Made Of
The defining stock is older frame housing — two-, three- and four-family houses from before 1930 on narrow lots — a very large share of it converted to student rental. Conversion matters: subdividing a house creates shared plumbing risers and connects wall voids between units in a way the original construction never did, giving German cockroaches and bed bugs a route between apartments.
Balloon framing is common, so the wall cavity runs from sill plate to attic and a mouse entering at grade is heard on the top floor.
Student tenancies concentrate the problems. Nine-month leases mean a comprehensive turnover every summer, furniture moves in and out constantly, second-hand and kerbside furniture is the norm, and a bed bug introduction in one house spreads through a social network rather than only through a building. Landlords are often absentee and treatments get authorised late and partially.
Downtown adds mixed-use buildings with commercial kitchens beneath residential floors, plus newer mid-rise development with trash rooms and riser chases.
The Calls We Get Most in New Brunswick
Bed bugs in student rentals, heaviest at the start and end of term. Turnover plus second-hand furniture plus dense social movement between houses.
German cockroach through a converted multi-family house, all floors, on the shared kitchen riser.
Roaches from a ground-floor restaurant into the apartments above. Common downtown and rarely addressed as one problem.
Mice on upper floors with entry at the sill. Balloon framing.
Water bugs in cellars after heavy rain. Combined sewer surcharge through floor drains.
Rats along the rail corridor and behind the downtown food businesses.
Basement pests and rodents after the river comes up.
Local Rules and Who to Call in New Brunswick
New Brunswick's health department and code enforcement handle pest and property maintenance complaints, and the city operates a rental inspection regime that student tenants in particular should know exists. Rental buildings of five units or more are also registered under the Hotel and Multiple Dwelling Law and inspected on a cycle by the New Jersey Department of Community Affairs. Pests in a rental are the owner's responsibility, not a tenant expense — report in writing, keep the copy, and escalate to the city if nothing happens. If you are a student renting from an absentee landlord, that written record is worth more than anything else you can do. The Middlesex County mosquito control programme treats public-side standing water at no cost.

New Brunswick — Local Questions
We are students and the whole house has bed bugs. Who pays?
The landlord. A bed bug infestation in a rental is a habitability and maintenance condition, not a tenant expense, regardless of who brought them in. Report it in writing to the landlord or agent, keep a copy, give a reasonable window, then take it to city code enforcement if nothing happens. Do not buy over-the-counter sprays in the meantime: they are pyrethroids, resistance is widespread, and being repellent they scatter the population into the wall voids and into the next bedroom.
There is a restaurant below our apartment and we have roaches. Connected?
Almost certainly. A commercial kitchen gives continuous food, warmth and harborage, and the plumbing and utility penetrations between the commercial space and the floors above are a direct route. Treating the apartments alone will not hold. The building has to be handled as one system, with the commercial space treated and the penetrations sealed — and that is the owner's responsibility.
