Winter Rat Problems in Bristol and Bath: A quick guide why rats come indoors in winter

When winter arrives in Bristol, Bath and the surrounding South-West, rats don’t go into

hibernation. As the weather turns colder and natural food sources dwindle, they look for

warmth, shelter and easy meals. Lofts, cellars and wall cavities in older terraced houses or

Georgian townhouses provide cosy nesting sites, while unsealed food containers, bird feeders, compost heaps and pet bowls give them plenty to eat. Damaged drains, loose roof tiles and gaps around pipes and skirting boards are common entry points in local properties.

Winter Rat Problems in Bristol and Bath

How to tell if rats are present

Early detection helps to avoid a full-blown infestation. Look for dark droppings about the size

of a grain of rice, gnaw marks on food packaging, wood or cables, greasy rub marks along walls,

and footprints or tail marks in dusty areas. Rats are mostly nocturnal, but you may hear

scratching, scuttling or grinding noises in the walls or loft at night. A strong musky smell in

cupboards or basements can also be a warning sign.

Why rat infestations are a serious issue

Rats aren’t just unpleasant; they can spread serious diseases through their urine and

droppings, including leptospirosis (Weil’s disease), salmonella, listeria and hantavirus. They

also gnaw constantly to keep their teeth in check. This can damage wiring and pipework,

sometimes causing electrical fires or flooding. Because a female rat can produce several litters a

year and young become mature within weeks, a small problem can quickly grow if ignored.

Why professional control works best

Controlling rats isn’t as simple as putting down poison. Rats are highly intelligent and wary of

new objects, so poorly placed traps or amateur-use baits often fail. Misused rodenticides can be

dangerous to pets, wildlife and children, and overuse contributes to poison-resistant “super

rats”. A trained pest controller will carry out a thorough inspection to identify entry points and

the scale of the infestation, advise on proofing and housekeeping, and use the most appropriate

traps or professional-only rodenticides in a safe, targeted way. They will also follow up to

ensure the infestation is fully resolved.

Practical prevention tips

Block entry points: Fit bristle strips to external doors, repair cracked bricks and

mortar, seal gaps around pipes and vents, and replace missing roof tiles.

Check drains: Have a professional inspect drains for faults or redundant connections

and install one-way rat valves where needed.

Store food securely: Keep food and pet food in sealed containers, fix dripping taps, and

clean up spills promptly. Use secure, lidded bins and position compost bins away from

buildings.

Keep gardens tidy: Trim tree branches and climbing plants away from roofs, clear

clutter and stacked wood, and avoid leaving fallen fruit or birdseed on the ground.

Work with neighbours: Rats travel along terraces and shared cavities, so coordinate

proofing and waste management with neighbours and landlords.
