Rat inspection

A professional rat inspection is the first step in reclaiming your home. Unlike basic DIY checks, a specialist survey identifies not just where the rats are, but how they are getting in and what is sustaining them, ensuring a long-term solution rather than a temporary fix.

What Does the Work Involve?

• Internal Survey: A thorough check of the loft, cellar, and floor voids for droppings, "smear marks" (grease from fur), gnaw damage, and nesting materials.
• External Perimeter Check: Inspecting the garden, outbuildings, and shed foundations for burrows, active runways, and gaps in the brickwork.
• Drainage Assessment: Checking gullies, manholes, and pipework entry points, as many UK rat infestations originate from faults in the sewer system.
• Kitchen & Utility Audit: Moving appliances to check for entry points behind kickboards and around plumbing stacks.
• Proofing Identification: Identifying specific structural defects, such as broken air bricks or gaps around waste pipes, that require sealing.
• Written Report: Providing a detailed assessment of the infestation level, recommended treatment plan, and a quote for proofing works.

Typical Costs

Prices vary based on property size and location, with London and the South East typically seeing higher rates. The severity of the infestation also dictates the amount of bait or traps required and the complexity of the cleanup operation.

How Long Does It Take?

• Initial Inspection: 1 to 2 hours for a standard three-bedroom semi-detached home.
• CCTV Drain Survey: 1 to 3 hours, depending on the accessibility of manholes.
• Treatment Duration: Usually 3 to 4 weeks, involving multiple visits to monitor bait uptake and remove carcasses.
• Proofing Works: Half a day to two days, depending on whether masonry work or specialist mesh installation is needed.

DIY or Professional?

While you can buy traps and bait at hardware stores, DIY rat control often fails because rats are "neophobic"—highly suspicious of new objects. Amateur-grade poisons are also significantly weaker than those available to professionals, often leading to bait resistance.

Hiring a professional is strongly recommended due to the health risks of handling rat waste and the strict UK regulations regarding rodenticide use. A professional will ensure that poisons are placed in "tamper-resistant" stations, protecting your pets and local wildlife from accidental secondary poisoning.

Choosing the Right Tradesperson

• Check Qualifications: Look for technicians certified by the British Pest Control Association (BPCA) or the National Pest Technicians Association (NPTA).
• Insurance: Ensure they hold public liability insurance specifically covering pest control activities.
• Integrated Pest Management (IPM): Choose a tradesperson who focuses on "proofing" (blocking entry) rather than just repeatedly laying poison.
• Ask about guarantees: Will they return for free if the rats reappear within a month of the treatment ending?
• Safety first: Ask how they plan to protect your children and pets from the treatment methods used.

UK Regulations

• CRRU (Campaign for Responsible Rodenticide Use): Professionals must follow this code to prevent poison from entering the wider food chain.
• The Prevention of Damage by Pests Act 1949: This gives local authorities the power to compel homeowners to deal with infestations that affect the wider community.
• Wildlife and Countryside Act 1981: Certain methods of control are restricted to ensure non-target species (like hedgehogs or birds of prey) are not harmed.
• Waste Disposal: Professional pest controllers must dispose of carcasses and contaminated materials as hazardous waste.

Common Problems

• Treating Symptoms, Not Causes: Killing the rats currently in the house without sealing the entry points ensures a new colony will move in within weeks.
• Ignoring the Drains: Roughly 90% of internal rat problems in the UK are linked to damaged sewer pipes or redundant junctions.
• Poor Housekeeping: Leaving bird feed out or failing to secure compost bins provides a "high-protein" food source that makes traps and baits less attractive to rats.
• Unfinished Treatments: Homeowners often stop the process once the scratching noises cease, but failing to complete the baiting cycle allows the remaining rats to breed rapidly.

Frequently Asked Questions

How do I know if I have rats or mice?

Rat droppings are the size of an olive stone (10-15mm) and spindle-shaped, while mouse droppings are the size of a grain of rice. Rats also leave larger gnaw marks and often produce a distinct, ammonia-like smell.

Is the poison safe for my dog or cat?

Professionals use lockable, tamper-proof bait stations that prevent pets from reaching the rodenticide. They will also place bait in areas pets cannot access, such as lofts or behind kitchen units.

Why can I hear scratching at night but see no rats?

Rats are nocturnal and excellent climbers. They often live in the wall cavities or loft space, using the "superhighway" of pipes and cables to move around the house unseen.

Should I get a CCTV drain survey?

If you have recurring rat issues despite baiting, a drain survey is essential. It identifies cracks or collapsed pipes that allow rats to exit the sewer system and enter your wall cavities.

Can I stay in the house during treatment?

Yes. Modern rat treatments do not require you to vacate your home. The only exception is if a specialist "gas" treatment or heavy-duty fogging for sanitisation is being carried out, which is rare in residential settings.

Will the council do it for free?

Most UK councils now charge for pest control services, and their rates are often similar to private contractors. Private firms usually offer faster response times and more thorough proofing services.
