Common rat species in the UK
Rats are found across farms, estates, warehouses and grain stores in Yorkshire. Two main species live in the UK — the brown rat (Rattus norvegicus) and the black rat (Rattus rattus).
Knowing which one you’re dealing with helps you control them properly.
Brown rat in the UK (Rattus norvegicus)
Where brown rats are found in Yorkshire
Brown rats, also called sewer rats, are the most common species in the UK. You’ll find them in:
- Farms and livestock sheds
- Commercial buildings and warehouses
- Drains, sewers and ditches
- Grain stores and barns
See how we handle infestations on our rat pest control page.
Key features of brown rats
- Size: Up to 25 cm long (excluding tail)
- Tail: Shorter than the body
- Ears: Small and thick
- Fur: Brown or grey with a lighter underside
They build burrows near buildings or under sheds. You may notice soil mounds or fresh digging. Learn more about how we locate burrows through our pest control services.
Behaviour
Brown rats are strong swimmers and excellent diggers. They move through drains and burrow into foundations. They breed quickly, producing several litters each year!
Black rat in the UK (Rattus rattus)
Where black rats live
Black rats, sometimes called ship rats, are rare in Yorkshire. They prefer ports, docks, or older coastal buildings. In some cases, they can appear in large food storage areas or warehouses receiving imported goods.
Visit our commercial pest control service page to see how we deal with rat problems in large sites.
Key features of black rats
- Size: Smaller than brown rats, around 20 cm long
- Tail: Longer than the body
- Ears: Larger and thinner
- Fur: Black or dark grey
They are skilled climbers. They often live in lofts, rafters, and upper levels of buildings. If you hear scratching high up at night, it could be black rats.

Signs of rat activity in Yorkshire
Recognising the species isn’t always easy, but rat signs are clear.
Look for
- Droppings (dark brown, up to 20 mm long)
- Gnaw marks on wood or plastic
- Burrows near walls or fences
- Smears or grease marks on surfaces
- Scratching or movement at night
If you notice these, visit our pest proofing service page to learn how we secure entry points.
Health risks from rats
Both brown and black rats spread diseases like leptospirosis and salmonella. Their droppings and urine contaminate food and surfaces. They also carry fleas and mites.
Our agricultural pest control service helps protect farms and grain stores from these risks.
