How To Get Rid of Rats

The discovery of rats within a home or business premises is deeply unsettling. Such an event naturally triggers significant concern, stemming not only from the immediate health risks associated with disease transmission but also the potential for substantial structural damage and negative impacts on reputation. Rats are exceptionally adaptable and prolific breeders, with a female capable of producing numerous offspring every three weeks. This rapid reproductive cycle makes swift and effective treatment an absolute necessity. Whether you are a private homeowner or a commercial entity, the fastest, most certain path to eliminating a rat infestation is engaging a professional pest controller. At Rentokil, we possess deep expertise in pest control and handle rat problems daily, guaranteeing that your issue will be resolved quickly and comprehensively.

If you observe signs of rat activity, the initial step in self-managed control involves precise identification of the entry points and the primary attractants. While various over-the-counter DIY products like traps and poisons are available, these should be viewed as supplementary measures after implementing core environmental controls. The fundamental key to rat control is pinpointing their source of ingress and sustenance.

A successful strategy for rat control begins with a precise assessment of the infested area. By systematically inspecting specific zones and identifying key indicators, you can pinpoint the extent of the problem and the best control approach.

1. Nesting & Harbourage

• Indicators to Look For: Examine the area for burrows, which appear as holes in the ground, typically measuring 6cm – 9cm in diameter.
• Inspection Locations: Focus on areas that provide security and shelter, such as underneath garden sheds, within woodpiles, or inside unused outbuildings. The dominant species encountered in these ground nests is often the Brown or Norway Rat (Rattus norvegicus).
• Significance for Control: Identifying these locations is crucial for confirming the core population center of the infestation.

2. Travel Routes

• Indicators to Look For: Search for runs (runways). These are smooth, distinct tracks created in dirt, grass, or mud by the repeated movement of rats. These pathways follow habitual routes between their harbourage and feeding sites.
• Inspection Locations: Check along walls, fences, and borders of the property, where movement is often concealed.
• Significance for Control: Mapping these travel routes is essential for strategically placing control methods (e.g., traps or bait stations) for maximum efficacy.

3. Smells

• Indicators to Look For: Detect any potent, musty odor that becomes noticeable in areas of concentrated activity. This distinctive smell is often caused by accumulated urine and droppings.
• Inspection Locations: Primarily observed in confined or poorly ventilated spaces like basements, under floor voids, or behind storage areas.
• Significance for Control: The presence of this odor confirms a significant and often long-standing rat infestation population density.

4. Food Sources

• Indicators to Look For: Identify unsecured food supplies that are attracting the rodents. This includes seeds spilled from bird feeders (which can contain compounds that increase rodent resistance to certain poisons), exposed contents of compost bins or food waste containers, or fallen fruit from trees.
• Inspection Locations: Focus on areas immediately outside kitchens, gardens, and waste disposal points.
• Significance for Control: Removing or securing these food sources is the most vital step in stripping the rodents of the primary resource sustaining the infestation.

The subsequent crucial phase is implementing environmental control actions. The goal is to render your property unattractive to rats by systematically eliminating their access to both food and harbourage (shelter). Shelter is as vital as food for a rat's survival. By focusing on these controls, you can often deter rats without the immediate need for chemical solutions.

1. Remove Harbourage: Systematically clear away disused items, such as stacks of wood, piles of bricks, general waste, and dense, overgrown vegetation, which provide ideal nesting sites.

2. Secure Food & Water: Store all foodstuffs in genuinely rodent-proof containers and bins. Critically, remove all accessible water sources, which could range from standing water in sagged covers to outdoor ponds or containers.

3. Seal Gaps (Proofing): Rats exploit defects in the building fabric. Install robust wire mesh or brick covers over all external holes and vulnerable entry points. This proofing provides the most effective long-term solution. Furthermore, defects in drainage systems are common entry points; a professional drain survey can highlight and address these issues.

If rat activity persists after rigorous environmental controls are in place, you may consider over-the-counter traps and rodenticides. However, these readily available products for domestic use often present significant drawbacks:

• Reduced Efficacy: Over-the-counter poisons are typically weaker formulations compared to professional-grade products. The biggest difference between amateur and professional is pack size - so amateur products tend to be quite expensive.
• Resistance Issues: Rats can possess genetic traits conferring resistance to certain active ingredients, potentially rendering your DIY efforts futile.
• Non-Target Risk: All rodenticides must be deployed in strict accordance with the label instructions to safeguard children, domestic pets, and native wildlife from accidental or secondary poisoning.
• Bait Volume: A single adult rat can consume up to 30g of food daily. Ensuring a sufficient volume of bait is available to match the scale of the infestation is paramount for successful eradication. Given the smaller pack sizes this can be costly and if under baited can lead to a build up in resistance to rodenticde and exacerbation of the problem

• Certified Professionals: All treatments are executed by fully qualified technicians (Level 3 Award in Pest Management Services – Trained Professional User).

For Residential Premises

Effective rat control in a domestic environment demands careful deployment and protection of bait due to the presence of people, pets, and non-target species.

• Targeted Control: We precisely identify and treat activity within high-risk areas like burrows, waste piles, sheds, garages, and compost heaps.
• Drainage Solutions: We can carry out specialist rat-specific drain surveys and necessary remedial works, recognizing that defective drainage is a common entry point.
• Bait Protection: When rodenticides are required, we utilise tamper-resistant bait stations or secure, covered bait points to prevent access by non-target animals and humans.

For Commercial Businesses

Rodents present a serious threat to public and animal health, hygiene standards, and can cause irreparable damage to stock, building integrity, and corporate reputation.

• Food Sector Compliance: Operators of food premises have statutory obligations to maintain an active pest control system. We provide compliant solutions tailored to specific audit specifications.
• Large Institutions (Hospitals, Schools): Our strategy is designed to account for the presence of vulnerable individuals and restricted access zones. We meticulously survey all potential activity points.
• Risk Mitigation: We execute comprehensive site surveys and risk assessments (including Site and Environmental Risk Assessments) to ensure the least invasive, yet highly effective, control methods are employed, thereby minimising risk to non-target species and the environment.

  What gets rid of rats fast?

  The fastest and most reliable way to eliminate an active rat infestation is through a strategic combination of professional-grade snap traps and rodenticides, deployed by qualified pest control experts.

  • Professional Treatment: Rodenticides used by professionally qualified pest controllers are significantly more effective than readily available DIY options. They are deployed with expertise, accounting for factors like rat resistance, Neophobia (fear of new objects), and ensuring safe and secure placement.
  • Snap Traps: When placed correctly along established rat runways (typically close to walls) and baited with highly attractive food (like peanut butter or dried fruit), traditional snap traps offer a quick, non-toxic elimination method with immediate confirmation of success. However, rodenticides are generally more efficient for larger, widespread infestations.
  • Immediate Action is Key: The overall speed of eradication relies heavily on immediately removing all competing food and water sources and thoroughly sealing entry points so that new rats cannot replace the ones you eliminate.

  How do you get rid of rats naturally?

  The most effective "natural" (or non-lethal) methods focus on robust prevention and deterrence by systematically removing the three things that attract them: food, water, and shelter.

  1. Exclusion (Rodent Proofing): This is the most essential step. Block all entry points using chew-proof materials, such as galvanised stainless steel mesh. Rats are highly flexible and can squeeze through gaps as small as 20mm (about 0.8 inches).

  2. Remove Attractions: Secure all rubbish bins with tight-fitting lids. Store pet and bird food in strong, airtight containers. Immediately clear up any fallen fruit, spilled bird seed, or pet food residue.

  3. Tidy Up: Eliminate potential hiding and nesting spots (harbourages) by removing overgrown shrubbery, woodpiles, and clutter in sheds, basements, lofts, or attics.

  Do rats hibernate?

  No, rats do not hibernate.

  Rats remain metabolically active and forage all year round. During periods of cold weather, rats simply seek warm, sheltered, and dry places to nest and continue to forage daily for food and water. This is why you often see increased rat activity indoors during autumn and winter, as they seek refuge from colder, outside temperatures.

  Will rats leave if one dies?

  No, the presence of a single dead rat will not cause the rest of the colony to leave the area.

  There are several reasons why the colony will remain established:

  • Danger Signal Overridden: While the scent of a dead rat may cause others to be temporarily cautious (a behaviour known as avoidance), the overwhelming needs for consistent food and secure shelter will quickly override any temporary fear.
  • Potential Food Source: In environments where food is scarce, rats are known to exhibit cannibalistic behaviour. The colony may consume the carcass for nourishment and essential nutrients, meaning the dead rat may actually attract rather than deter the survivors.
  • Colony Size: A single deceased rat is a strong indicator of an active and established colony. A solitary death will not prompt the entire rat colony to abandon a reliable source of food and shelter that is vital for their survival and breeding success.
