My Neighbour Has Rats: Will I Get Them?

Finding out a neighbour has rats is unsettling, and the worry that they might spread to your property is completely understandable. The honest answer is that the risk is real but not inevitable, and there is quite a lot you can do about it.

How rats spread between properties

Rats do not respect boundaries. A colony based in one garden, outbuilding or beneath one house will naturally explore the surrounding area in search of food, water and shelter. If your neighbour's infestation is left untreated, or if their property simply offers better conditions than yours, rats will move along fence lines, through hedgerows, under sheds and through any gap in brickwork or pipework that connects one plot to the next.

The most common routes between neighbouring properties are underground drainage runs, gaps around shared garden walls, compost heaps, overgrown borders and bird feeders. Rats are capable burrowers and climbers. A gap of roughly 13mm is enough for a young rat to squeeze through, so a property that looks sealed to the eye can still be accessible.

It is also worth knowing that rats tend to follow a core home range, typically somewhere between 30 and 100 metres from their nest. If your neighbour's property sits within that radius, your garden is well within foraging distance.

Signs to watch for in your own home and garden

The earlier you catch activity, the simpler and less disruptive treatment tends to be. Check regularly for the following:

  • Droppings. Dark, tapered and roughly the size of a large grain of rice. Fresh droppings are a clear sign of active presence.
  • Gnaw marks. Rats gnaw constantly to keep their incisor teeth in check. Look for marks on cables, pipework, timber joists, food packaging and around the base of external doors.
  • Runs and smear marks. Rats habitually travel the same routes. You may see compacted grass, bare earth tracks close to walls, or greasy smear marks where their bodies brush repeatedly against surfaces.
  • Burrows. Rats excavate burrows with a clean, rounded entrance hole, often found under sheds, along the base of walls or in compost heaps.
  • Sounds at night. Scratching, scurrying or gnawing sounds from beneath floorboards or in wall cavities, particularly after dark when rats are most active.

If you notice droppings or other signs and are unsure whether they are from rats or mice, a qualified pest control technician can identify the species quickly and advise on the appropriate course of action.

A note on health: rat droppings and urine can carry diseases including Weil's disease (leptospirosis). Avoid touching droppings with bare hands, clean affected surfaces with disinfectant and wash your hands thoroughly afterwards. If you develop a fever, muscle aches or jaundice after potential exposure to rat droppings or contaminated water, contact your GP or call NHS 111 promptly.

Steps you can take right now to reduce your risk

You cannot control what happens on your neighbour's property, but you can make your own far less attractive to any rats looking to expand their territory.

  • Remove food sources. Store bird seed, pet food and compostable waste in sealed, hard-sided containers. Clear fallen fruit promptly. Rats need only a small amount of food each day, so even seemingly minor sources matter.
  • Cut off water sources. Fix dripping taps, clear standing water and ensure water features are not left stagnant and accessible at ground level.
  • Reduce harborage. Clear clutter from sheds and garages. Cut back dense ground cover close to the house. Move woodpiles away from exterior walls.
  • Seal entry points. Pack wire wool into gaps around pipework where it enters the building, then cover with a suitable filler. Fit bristle strips to the base of external doors and check that air bricks are intact and covered with fine mesh.
  • Check your drains. Cracked or broken drain runs are a common access route. A drainage survey can identify vulnerabilities before rats exploit them.

Taking these steps promptly gives you a much stronger chance of keeping a neighbour's rat problem from becoming your own.

When to call a pest control professional

If you spot any signs of rats on your property, acting quickly matters. A small, early infestation is far easier and faster to resolve than one that has been allowed to establish over several weeks. Getting a proper survey and written quote is always the sensible first step, as treatment requirements vary depending on the size of the infestation, your property type and how accessible the affected areas are.

Frequently asked questions

If my neighbour has rats, will I get them?
There is a genuine risk, though it is not certain. Rats explore well beyond their nesting site, and if food, water or shelter on your property is more accessible than on your neighbour's, they will move in. Removing attractants and sealing entry points significantly reduces the likelihood.
How quickly can rats spread from one house to another?
Rats can move between neighbouring properties within days once they begin exploring. An untreated colony tends to grow, and as numbers increase so does the pressure to find new territory. Acting early, whether on your own property or by encouraging a neighbour to seek treatment, limits how quickly a problem spreads.
What should I do if my neighbour has rats and won't deal with it?
You can report a persistent rat infestation to your local council, who have powers to investigate and, in some cases, require a property owner to address the problem. In the meantime, focus on making your own property as unattractive as possible by eliminating food sources and sealing potential entry points.
Can rats get into my house through the drains?
Yes, rats regularly enter properties through drainage systems, particularly where pipes are cracked, poorly jointed or have open access points. Having your drains surveyed and fitting appropriate non-return valves or drain blockers is one of the most effective preventive measures available.
What are the first signs of rats in a house or garden?
The most common early signs are droppings, gnaw marks, greasy smear marks along walls, burrow holes in soil and scratching sounds at night. Even a small number of droppings is worth taking seriously, as a few visible ones usually indicate more activity nearby.
Is it safe to clean up rat droppings myself?
You can clean up small amounts of droppings safely provided you wear disposable gloves and a mask, and use a disinfectant solution rather than dry sweeping, which can spread contaminated dust. If you feel unwell after contact with rat droppings or contaminated water and develop symptoms such as fever, muscle pain or jaundice, contact your GP or call NHS 111 promptly.
