Norway Rat Signs — Burrows, Runways and Droppings

The Norway rat (Rattus norvegicus) is the rat this region has: heavy and blunt-nosed, with a body of up to about 25 centimetres and a slightly shorter scaly tail, living at ground level and below it.

• Burrow entrances. Round holes roughly the width of a tennis ball, with smooth, packed edges and a fan of loose soil thrown out in front. A clean rim with no cobwebs or leaf litter means the hole is in use.
• Runways. Narrow paths worn bare through grass or packed into soil along walls, fences and foundation edges. Rats repeat the same route every night.
• Droppings. Dark, blunt-ended and about the size of a raisin or an olive pit, usually dropped in small clusters along runways and near food.
• Rub marks and gnawing. Dark smudges where fur brushes the same corner again and again, and chewed plastic bins, doors and pipe insulation.
• Sound. Heavier than mice — scrabbling, dragging and gnawing, mostly from dusk into the early morning.

A rat seen in daylight is worth taking seriously. Rats keep to the dark by choice, so daytime activity usually means crowding, a disturbed burrow or a food source they are competing for.

In attached neighbourhoods the first signs are usually in the narrow rear yard: a hole under the concrete pad, a runway along the fence behind the bins, or droppings in the cellar stairwell.

Where Rats Live on a Dense Block

Norway rats need three things within a short walk of each other: soil or rubble to dig in, water, and a reliable meal. Older attached blocks supply all three.

• Rear yards and alleys. Cracked concrete, loose pavers and soil strips along back fences are the classic burrow sites, usually right beside where the rubbish is kept.
• Cellar edges. Deteriorated mortar at the foundation, gaps around old coal chutes and areaway doors, and utility pipes that enter below grade.
• The sewer. Older combined sewer systems carry rats between blocks. A broken house lateral, a missing clean-out cap or a basement floor drain whose trap has dried out gives them a way up inside.
• Food nearby. Overflowing bins, bags left out overnight, restaurant refuse and bird seed thrown for pigeons feed far more rats than any single kitchen.

Because rats forage beyond one lot, the colony in your yard may be feeding two doors down. Success then means your lot sealed and clear, even while pressure continues on the block.

Removing Rats — the Order That Works

Rats are suspicious of anything new. A trap that appears overnight on a runway is often walked around for days. That caution, called neophobia, is why a rat program starts with pre-baiting: large rat traps go out baited but unset, placed along walls and runways inside covered boxes, and are only armed once the rats are feeding from them freely. Set them too early and the colony learns to avoid them.

Size matters. Mouse traps only injure rats. Rat work uses heavy snap traps or enclosed trap boxes, set perpendicular to the wall with the trigger on the runway, and plenty of them — rats rarely all feed from one spot.

Inside a multi-family building, trapping is the tool; rodenticide in occupied space risks rats dying in wall voids and ceilings between apartments.

Exterior bait stations. Outside, a program usually adds locked, weighted or anchored stations along the foundation and fence lines where runways are active. The strongest rodenticides — the second-generation anticoagulants — have been withdrawn from consumer products in the US and are limited to professional use for exactly this reason: an animal that eats them stays poisonous to the hawks, foxes, cats and dogs that may find it. Stations are checked and logged on every visit, and bait is removed once feeding stops rather than left out indefinitely.

Burrows. After treatment, active holes are packed with soil and checked on the next visit. A hole that has been dug open again is the clearest sign the colony is still there; a hole that stays closed across several visits is the sign it is not.

Dead rats and odour. A rat that dies inside a wall or ceiling produces a strong smell that can last one to three weeks. Flies gathering at one spot on a wall, or a stain on a ceiling, usually points to it. A reachable carcass is removed with gloves, bagged, and the area disinfected — soak droppings and nesting material with disinfectant before wiping, never sweep them up dry. Where it cannot be reached, ventilation and time are often the only option, which is one more reason interior work relies on traps.

What the visits look like.

• First visit: mark every burrow, runway and entry point inside and out; set pre-baited traps and, where needed, exterior stations; note what the rats are eating and drinking.
• Weekly visits: arm traps once feeding is steady, log catches and station feeding, and move equipment to where the activity is.
• Exclusion: seal the gaps the survey found — concrete and hardware cloth at the foundation, door sweeps, vent screens, pipe penetrations.
• Close-out: no fresh burrow openings, no new droppings and no feeding across two or three consecutive visits. That is the finish line, and it should be written down.

Landlords, Tenants and the Town

On a New Jersey rental property, a rat infestation is the owner's to correct as a housing maintenance condition, and in buildings with shared cellars, yards and refuse areas that is almost always the only practical arrangement — no single tenant controls the whole route.

If you rent, tell the owner in writing, with dates and photos of burrows, droppings or damage, and keep a copy. If nothing happens, the local health department or code enforcement office can inspect; buildings registered as multiple dwellings are also subject to state inspection by the Department of Community Affairs.

If you own, the refuse area is where money does the most good: lidded metal or heavy plastic bins, a pad that can be hosed down, and a rule that bags never sit on the ground overnight. Many towns also have ordinances on how rubbish must be stored and set out, and on vacant lots and overgrown yards that shelter rats — the municipal code office can tell you what applies on your street.

Why it matters beyond the damage. Rat urine can carry leptospirosis, a bacterial infection spread mainly through contact with the urine of infected animals, and rats contaminate food and food-contact surfaces with salmonella. Norway rats can also carry Seoul virus, a hantavirus, although human cases in this country are rare. Do not handle rats, nests or droppings bare-handed, and treat anything they have touched as dirty until it is cleaned and disinfected.
