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.

On a suburban lot, look under the deck, beside the shed, along the back fence and around the compost bin before looking in the house.

Where Rats Settle on a Suburban Lot

Rats are less common in detached neighbourhoods than in dense ones, but when they arrive they tend to settle into the same handful of places.

• Sheds and decks. A shed on skids or a low deck gives dry, dark cover with soft soil underneath. It is the most common burrow site we find on a detached lot.
• Food left outside. Bird feeders dropping seed, pet food stored in the garage, fallen fruit, open compost with food scraps and backyard chicken feed will each support a colony.
• Woodpiles and dense planting. Firewood stacked against the house and thick ground cover along the foundation hide both runways and burrow openings.
• Water. Ponds, dripping hose bibs, pool equipment and stormwater retention basins all draw them.
• Nearby commercial land. Houses backing onto shopping strips, restaurants, rail lines or construction sites see more pressure, because the colony's main food supply is next door.

From outside, the usual way in is low: a gap under the garage door, a hole where a utility line enters, or a crawlspace vent with a torn screen.

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.

Removing the food and cover goes alongside the trapping, or the next colony simply moves into the same spot. Feeders come down for a few weeks, firewood goes up on racks well clear of the walls, and compost goes into a closed, rat-resistant bin.

Digging barriers. The lasting fix for a shed or deck is a skirt of galvanised hardware cloth buried around the edge and bent outward in an L at the bottom, so a rat digging down meets mesh rather than soil.

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.

Neighbours, Ordinances and Health

On a detached lot the responsibility is simpler: the owner deals with their own property. What is harder is when the source is next door — an overgrown yard, a heap of rubbish, a feeder spilling seed.

A friendly conversation usually does more than anything else. If it does not, most New Jersey municipalities have property maintenance and nuisance ordinances covering rubbish, overgrowth and conditions that harbour rodents, enforced by the local code enforcement or health office. They can inspect and require the owner to correct it. For a rental house, the landlord is responsible for correcting an infestation; report it in writing first and keep a copy.

Where the source is a neighbouring food business, the local health department is the right contact.

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.
