Rats: A Guide to Understanding and Controlling Infestations
Fast, professional rat control for UK homes and businesses. Rentokil experts provide certified, and effective rat control and prevention solutions across the UK.
Rats are one of the most common pests in the UK and can pose a serious threat to your health, property, and peace of mind. If you’ve seen signs of rats, acting quickly is vital.
At Rentokil, we combine over 100 years of pest control experience with innovative technology and adhere by the Campaign for Responsible Rodenticide Use practices (CRRU-compliant) to protect homes and businesses from rat infestations safely and effectively.
Whether you’ve noticed gnawing, sounds at night or found droppings in the loft, our qualified technicians provide discreet, and dependable solutions across the UK.
The Risks of Rat Infestations
A rat infestation can quickly escalate from minor to major damage. Rats gnaw through wood, insulation, and electrical cables, leading to fire risks and expensive repairs. Their droppings and urine spread diseases such as Weil’s disease (Leptospirosis), Rat-bite fever, and Salmonellosis.
For businesses, a rat problem can lead to product contamination, reputational harm, and breaches of UK Food Safety and Health & Safety legislation. Rentokil’s CRRU-compliant pest control ensures risks are reduced responsibly while maintaining full legal compliance.
Understanding Rat Behaviour
Rats are adaptable, intelligent rodents that can quickly exploit weak points in a building. Understanding their habits helps prevent and control infestations effectively.
Black Rats vs Brown Rats
- Black rats (Rattus rattus) – agile climbers that often nest in lofts or roof spaces.
- Brown rats (Rattus norvegicus) – skilled burrowers, commonly found in sewers, gardens, or beneath outbuildings.
Our targeted treatments identify which species is present, allowing technicians to choose the safest and most effective control methods.
How Rats Enter Homes and Businesses
Rats can squeeze through gaps as small as 2 cm which is about the width of a thumb. That means a rat can enter through a space no larger than a £1 coin. They are also capable climbers and can scale rough brickwork, cables, and drainpipes to reach roof spaces and lofts.
Common access points include:
Damaged drains or pipework
Uncapped or cracked drainage pipes, old sewer connections left open after building work, or gaps where plumbing exits walls (such as behind washing machines, sinks or outdoor taps).
Gaps under doors or around dock levellers
Especially in garages, warehouses, or loading bays where brush strips or seals have worn away.
Cracks in brickwork or weep vents
Even a small crack in mortar can be gnawed wider by a determined rat. They will chew, dig, or enlarge any weak point to create an entry route.
Utility access points
Around gas pipes, air bricks, or cable entry holes for broadband or power supplies.
Rats are strong enough to gnaw through plastic, wood, and soft metal, and will dig around concrete footings if soil or insulation provides an easier path. They may also climb inside vertical pipes or soil stacks to gain entry through broken joints or roof vents.
The Rentokil Process
Effective Rat Control Methods for Your Home
DIY traps may catch one or two rats but rarely tackle the source of an infestation. Rentokil offers Integrated Pest Management that combines safe, professional solutions:
- Traps and Bait Stations: Secure, tamper-resistant boxes with traps or licensed rodenticides, used only by trained Rentokil technicians under CRRU guidelines.
- Environmental Proofing: Sealing entry points, improving waste management, and eliminating nesting areas.
- Hygiene Guidance: Reducing access to food and water sources.
Our pest experts use targeted techniques designed for both domestic and commercial environments.

Comprehensive Site Inspections
Each treatment begins with a full survey of your property to identify entry points, nesting areas, and contributing factors. From there, our experts design a plan suited to your specific risks and needs.
Rat Proofing to Prevent Infestations
Prevention is the most sustainable form of pest control. Denying rats access to food, water, and shelter dramatically reduces infestations.
- Store food in sealed metal or glass containers.
- Keep kitchens and outdoor areas tidy.
- Secure bins with tight-fitting lids.
- Maintain drains and repair structural gaps.
Rentokil’s Flexi Armour system provides robust, proofing solutions for homes and businesses.

Rats Frequently Asked Questions
-
What is the best way to get rid of rats?
The most effective, sustainable rat elimination strategy is a multi-step approach prioritising prevention and removal. Crucially, eliminate attractants (food, water, shelter) by sealing entry points with materials like wire mesh or cement, securing outdoor bins with tight-fitting lids, and clearing garden clutter. For active infestations, use traps (e.g., snap traps) or professional-grade rodenticides in secured bait stations. Due to rats' rapid reproduction, complex nest locations, and the need for safe, compliant treatment, hiring a certified pest control professional is advised for thorough inspection to identify entry points, safe targeted treatments, and advice on long-term proofing solutions.
-
Is it normal to see a rat in your garden?
Occasional rat sightings are more common than you think, as they thrive in UK urban gardens, parks and rural areas. Gardens provide essential food (bird seed, fallen fruit, compost), water (leaks, bird baths), and shelter (under sheds, decking, woodpiles) they need. Seeing one rat at dusk or at night may be minor. However, frequent daytime sightings or other signs like droppings, gnaw marks, or burrows (5–10 cm wide holes near structures) may indicate an established infestation nearby, requiring immediate action.
-
What scent will keep rats away?
Certain strong, pungent odours may deter rats temporarily, but they don’t solve infestations. Rats have a highly developed sense of smell, making them sensitive to strong odours like peppermint, eucalyptus, citronella and ammonia (mimicking predator urine). These scents can overwhelm their senses for a short time and disrupt their navigation and ability to find food. However they are short-term deterrents. Professional exclusion, rodent proofing and sanitation are essential.
-
What do rats eat?
Rats are opportunistic, adaptable omnivores, consuming a wide variety of plant and animal matter based on availability. Eating everything from discarded fast food, pet food, bird seed, grains, meat scraps and carcasses to fallen fruit, garden vegetables and content of compost bins. Some species show preferences, such as Norway rats favouring high-protein meats and pet food, while Roof rats usually prefer fruits. Their lack of fussiness is key to their success, highlighting the need to secure all food sources to help prevent an infestation.
-
Are rats dangerous?
Yes, wild rats are dangerous to human and pet health, and property. They are known carriers of serious diseases, transmitting illnesses like Leptospirosis, Salmonellosis, and Hantavirus through bites, scratches, droppings, urine, saliva, or parasites (fleas/mites). Their constant gnawing causes property damage, including chewing electrical wiring and plumbing, potentially creating fire hazards. Due to these risks, any confirmed rat infestation requires prompt, professional attention.
