What Are Rats Scared Of?
Rats are naturally cautious animals. They may avoid predators, sudden movement, loud unfamiliar noises, bright disturbance, new objects, strong smells and open exposed spaces. However, rats are also highly adaptable. If a property gives them food, water, warmth, shelter, nesting cover or access through drains and gaps, they may ignore things that seemed to scare them at first.
The honest answer is this: you may disturb rats temporarily, but you usually cannot scare away an established rat problem for long. Effective rat control depends on removing what rats need to survive: food, water, shelter, nesting areas and access routes. Bon Accord’s professional rat-control service is based on inspecting rat activity, identifying entry points, assessing drains where needed, applying targeted control and recommending proofing to reduce recurrence.
This is especially important in London, where rats are common around Victorian terraces, basements, lower-ground flats, mixed-use buildings, restaurants, communal bin stores, railway lines, canal routes, older drainage systems, gardens and blocks of flats. For London homes and businesses, the professional question is not only “What are rats scared of?” but “Why are rats here, where are they entering, and what needs to be corrected?”

Myth vs reality: what scares rats and what actually works
The most important message for clients is simple: rats may dislike certain things, but they stay where conditions help them survive. Smells, cats, lights or gadgets may disturb rats for a short time, but they will not repair a drain, seal a gap, remove food waste or make a warm nesting void disappear.
| Myth | Reality |
|---|---|
| Peppermint oil gets rid of rats | It may disturb rats briefly, but it does not block access, remove food, repair drains or remove nests. |
| Cats solve rat problems | Cats may scare or catch some rats, but rats can avoid cats through drains, walls, voids, gardens and night-time routes. |
| Dogs keep rats away permanently | Dogs may disturb rats, but they do not remove food waste, burrows, drain faults or entry gaps. |
| Ultrasonic devices clear infestations | Evidence for electronic repellent claims is weak, and supported proof is often lacking for established rat problems. |
| Leaving lights on keeps rats away | Rats prefer dark, sheltered routes, but they can still move through drains, walls, lofts, basements and covered paths. |
| Strong smells are the best rat deterrent | The best deterrent is removing food, water and shelter, then proofing entry points and drains. |
| DIY poison is the easiest answer | Rodenticides must be used carefully, legally and safely. If unsure, get professional advice. |
The truth: rats are cautious, not easily defeated
Rats survive because they are careful. They are usually wary of unfamiliar objects, unfamiliar smells, sudden changes and open spaces where predators could catch them. That cautious behaviour is one reason rats may avoid a new trap, bait box, strong smell or changed garden layout at first.
But caution is not the same as permanent fear. If the reward is strong enough — food waste, pet food, bird seed, a warm void, a drain route, or a safe nesting area — rats can adapt.
A rat may dislike peppermint oil, but it will still return if there is an open bin. A rat may avoid a dog for a while, but it may still use a drain or wall cavity at night. A rat may be disturbed by noise, but it may return once the building becomes quiet. A rat may avoid a new object, then become used to it.
The weakness of most online rat-deterrent advice is that it focuses on what rats dislike instead of what rats need. A proper rat-control plan must answer the real question: where are rats entering, what are they feeding on, and how can the conditions be corrected?
What rats may be scared of — and whether it solves the problem
| Deterrent | Are rats scared of it? | Does it solve an infestation? | Professional view |
|---|---|---|---|
| Cats and dogs | Sometimes | Not reliably | May disturb rats but does not remove food, access or harbourage. |
| Owls and predators | Naturally, yes | Not in normal buildings | More relevant outdoors than inside properties. |
| Sudden loud noises | Temporarily | No | May disturb rats briefly, but they often return when quiet. |
| Bright lights | Sometimes | No | Rats may avoid exposed areas but can adapt. |
| New objects | Often at first | No | Rats may avoid new traps or boxes due to caution. |
| Peppermint/eucalyptus scents | May avoid briefly | No | Short-term discomfort only; not a control plan. |
| Ammonia, bleach or mothballs | Strong smell may disturb briefly | No, and can be unsafe | Not recommended as normal home or business rat control. |
| Ultrasonic devices | May disturb briefly | Not reliable long-term | Rats may adapt and sound is blocked by obstacles. |
| Removing food/water/shelter | Makes the area unsuitable | Yes, essential | Core prevention step. |
| Proofing gaps and drains | Blocks access | Yes, essential | Key long-term solution. |
What rats are scared of indoors vs outdoors
| Location | Rats may avoid | What actually works |
|---|---|---|
| Inside houses | People, sudden noise, light, new objects | Inspection, entry-point proofing, food removal, drain checks and safe treatment. |
| Gardens | Open spaces, predators, disturbance | Remove bird food, pet food, compost access, clutter, decking voids and burrows. |
| Restaurants | Human activity and disturbance | Waste control, proofing, monitoring, door/gap repairs, drain checks and professional records. |
| Flats and blocks | Exposed corridors and busy areas | Inspect risers, bin rooms, basements, pipe gaps, drains and neighbouring units. |
| Lofts and wall voids | Direct disturbance | Find how rats entered, treat safely, then proof access points after control. |
| Drains | Very little if route is safe | Drain inspection, manhole checks and rat blockers where suitable. |
Stronger London context: why rats are hard to scare away in London
London gives rats many routes and harbourages. That is why a smell, cat or plug-in device is rarely enough.
- Victorian terraces and older pipe routes
- Lower-ground flats and basements
- Mixed-use buildings with restaurants below flats
- Railway lines and canal routes
- Communal bin stores
- Shared drains and manholes
- Converted houses split into flats
- Mansion blocks and service risers
- Commercial yards and loading bays
- Older wall cavities and floor voids
- Poorly sealed extensions
- Garden decking and sheds
For London clients, this page should make one thing clear: if rats have a route in and a reason to stay, they will not be reliably scared away.
Are rats scared of humans?
Rats are usually cautious around humans, but urban rats can live very close to people if food, shelter and access are available. They may avoid a person in the moment, but they are often active at night when people are asleep or when a building is quiet.
In London, rats commonly move through gardens, bin stores, basements, drains, wall cavities, lofts, under kitchen units, commercial yards, restaurant waste areas, voids below floors, service ducts and risers. Seeing a rat during the day can sometimes suggest that rats are comfortable in the area, food is easily available, or activity is already established.
Are rats scared of cats?
Rats have natural predator-avoidance behaviour, so cats may disturb them. However, keeping a cat is not a reliable rat-control method. Rats can avoid cats by using wall cavities, drains, lofts, underfloor voids, garden cover, sheds, decking, bins, waste areas and night-time routes.
Cats may catch young or careless rats, but they do not remove the reason rats are present. If there is food waste, bird seed, pet food, broken drains, gaps under doors or a warm nesting void, rats may continue. A cat may be a disturbance; it is not a proofing strategy.
Are rats scared of dogs?
Dogs may also disturb rats. Their smell, movement and barking can make rats cautious. But again, this is not a complete control method. Rats can avoid dogs by using drains, fences, wall cavities, under-decking spaces, sheds, roof voids, garden cover, gaps behind kitchen units and night-time movement.
Dogs can also be at risk if they come into contact with rats, rat urine, contaminated areas or rodenticides. A dog should not be used as the main rat-control plan. If there is confirmed rat activity, the safer approach is inspection, treatment, proofing and removal of attractants.
What smells are rats scared of?
Common online suggestions include peppermint oil, eucalyptus oil, garlic, chilli, vinegar, ammonia, bleach, mothballs and predator scent. Some strong smells may disturb rats temporarily, especially in a new area. However, they do not remove the infestation. They do not block holes, repair drains, stop access from sewers, remove food waste or destroy nests.
Should you use peppermint oil for rats?
Peppermint oil may make an area smell unpleasant to rats for a short time, but it is not a reliable solution for rats inside a house, flat, restaurant or commercial property. It also fades quickly and does not block entry points.
Should you use ammonia, bleach or mothballs?
No. These are not sensible pest-control solutions for normal homes or businesses. They can create health and safety risks, contaminate surfaces, irritate people and pets, and still fail to deal with the rat source.
What scent really keeps rats away?
No scent should be relied on as the main solution. The strongest “deterrents” are not smells. They are no accessible food, no accessible water, no harbourage, no open drain route, no entry gaps, no rubbish build-up and no nesting cover.
When deterrents are dangerous or a waste of money
Some deterrent ideas are not only weak, but can create safety problems or waste money.
Ammonia and bleach
These are not proper rat-control tools. They can irritate people and pets, contaminate areas and create a false sense of security. They do not remove entry points, nesting areas or food sources.
Mothballs
Mothballs are not a professional rat-control solution and should not be used casually in living areas, kitchens, lofts or commercial premises.
Ultrasonic plug-ins
Ultrasonic devices are often sold as easy fixes, but supported evidence is weak. They should not replace inspection, proofing, drain checks or professional treatment where rats are established.
Glue boards and random DIY poison use
Glue boards and rodenticides raise welfare, legal and safety concerns. Incorrect poison use can endanger children, pets, wildlife and non-target animals. It can also fail to solve the cause if rats are entering through drains, holes, vents or neighbouring areas.
Are rats scared of noise?
Rats may be startled by sudden loud noise, vibration or unfamiliar activity. This can make them avoid an area temporarily. But if the area still has food, water and shelter, they may return once the disturbance stops.
This is why banging, shouting, radios, music or vibration devices rarely solve a rat problem. Rats may change their route, hide deeper in a void or become active at quieter times. Noise can move the problem; it does not remove the cause.
Do ultrasonic rat repellents work?
Ultrasonic rat repellents are marketed as easy plug-in solutions, but they are not reliable for established rat problems. In practical terms, sound may not reach behind walls, under floors or inside loft voids; furniture and appliances can block the effect; rats may avoid one area and use another route; established rats can adapt; and food and shelter usually override discomfort.
For a client with rats in a London property, an ultrasonic plug-in should not replace professional inspection, drain checks, baiting, trapping, proofing or waste control.
Are rats scared of lights?
Rats generally prefer dark, sheltered routes, which is why they are often active at night. But leaving lights on is not a reliable control method. Rats can still move through drains, cupboards, wall cavities, lofts, basements, under decking, under kitchen units, covered garden routes, service ducts and risers.
Lights may help you monitor activity, but they will not solve broken drains, open air bricks, food waste, unsealed bins, burrows, loft entry points, gaps under doors, wall cavity access or restaurant waste problems.
Are rats scared of open spaces?
Rats usually prefer covered routes because open spaces expose them to predators and disturbance. This is why they often run along walls, fences, skirting edges, garden boundaries, pipe runs and cluttered areas.
In gardens and yards, rats are more comfortable where there is decking, thick shrubs, overgrown vegetation, stacked wood, rubbish, garden waste, old furniture, sheds, compost, bird food and bins. Removing cover can make rats less comfortable, but it should be combined with food control, proofing and professional treatment where there is established activity.
What rats are really attracted to
To understand what rats are scared of, you must also understand what they are attracted to. Rats will tolerate disturbance if the reward is high enough.
- Food waste
- Open bin bags
- Bird seed
- Pet food
- Compost
- Restaurant waste
- Grease and food residue
- Damaged drains
- Broken manhole covers
- Water sources
- Clutter
- Decking voids
- Sheds
- Overgrown gardens
- Wall cavities
- Warm lofts and basements
Rats remain where food, water, shelter and access routes make survival easy. This is why proper rat control looks at the environment, not only the visible rat.
What actually keeps rats away?
The best rat deterrent is not one smell, one sound or one gadget. It is an integrated approach: remove food, remove water, remove shelter, proof entry points and inspect drains where needed.
1. Remove food
- Use sealed bins.
- Do not leave bin bags outside loose.
- Remove food waste quickly.
- Stop feeding birds temporarily if rats are active.
- Clear spilled bird seed.
- Do not leave pet food out overnight.
- Store dry goods in sealed containers.
- Clean restaurant waste areas.
- Keep food stores organised.
- Remove fallen fruit in gardens.
2. Remove water
- Check leaking taps.
- Check broken gullies.
- Remove puddling in yards.
- Investigate drain defects.
- Repair leaking pipework.
- Do not leave water bowls out unnecessarily.
- Clear blocked gutters.
- Investigate damp basements and overflowing waste areas.
3. Remove shelter
- Reduce clutter.
- Remove garden waste.
- Cut back overgrown shrubs.
- Clear piles of wood and rubbish.
- Remove unused materials.
- Block under-decking access where appropriate.
- Repair open shed gaps.
- Investigate voids around buildings.
4. Proof entry points
- Gaps under doors
- Broken air bricks
- Holes around pipes
- Gaps in external walls
- Broken vents
- Missing drain caps
- Damaged manhole covers
- Redundant drain connections
- Poorly sealed building works
- Loose basement doors
- Gaps around service cables
Inspect drains where rats keep returning
In London, drains are a major rat route. Rats can use underground drainage systems and may enter through damaged pipes, open inspection chambers, broken manhole covers, redundant connections or flexible toilet pan connectors.
If rats keep returning, or if activity is linked to bathrooms, ground-floor kitchens, basements, manholes or outside drains, drain inspection may be more useful than buying smells, gadgets or deterrents. A rat blocker may be suitable in some drain-linked cases, but it should be part of a wider treatment and proofing plan.
What are rats scared of in gardens?
In gardens, rats dislike exposed open areas, lack of cover and lack of food. They prefer gardens that give them shelter and a reliable food source.
Rats are more likely in gardens with bird feeding, spilled seed, compost with food waste, pet food outside, chicken/rabbit/guinea pig feed, open bins, overgrown shrubs, decking, sheds, wood piles, garden waste and quiet nesting areas.
To make a garden less attractive, stop bird feeding temporarily if rats are active, use bird feeders with trays, clear spilled seed daily, secure compost, remove pet food, keep bins sealed, reduce clutter, cut back overgrowth, block shed gaps, inspect decking if needed and avoid leaving food waste outside. A garden rat problem is rarely solved by smell alone. The aim is to remove food, shelter and safe routes.
What are rats scared of in houses?
Inside houses, rats are usually less influenced by smells and more influenced by access, food and shelter. If rats are in a house, they may be using underfloor voids, lofts, wall cavities, pipe routes, kitchen gaps, cellar or basement spaces, broken drains, external wall gaps, damaged vents, open air bricks, redundant pipes or gaps around extensions.
Common signs include scratching, gnawing, droppings, smells, greasy smear marks, disturbed insulation, damaged food packaging and noises at night. A strong smell or ultrasonic plug-in will not close a pipe gap or repair a drain. The best approach is inspection, treatment and proofing.
What are rats scared of in flats and blocks?
In flats, rats may be using building routes rather than coming from inside one flat. They may move through risers, service ducts, communal bin rooms, basements, pipe boxing, wall cavities, drain routes, plant rooms, gaps around waste pipes or commercial premises below flats.
For tenants, landlords and managing agents, the key is to identify whether the issue is inside the flat, in a communal area or connected to a building defect. A flat tenant may keep their home clean but still have rat activity if there is a building-level issue, drain route, riser gap or communal bin problem.
For London flat blocks, this page should naturally link to Bon Accord’s rat control, property management and drain investigation services.
What are rats scared of in restaurants and food businesses?
Restaurants, cafés, takeaways, hotels and commercial kitchens should not rely on deterrent myths. Food businesses need inspection, prevention, monitoring and fast professional action.
Rats are usually attracted to food businesses because of food waste, bin bags, grease, damaged food packaging, open delivery areas, stock rooms, poor waste storage, gaps under doors, drains, basements, service yards and neighbouring premises.
For restaurants, the best “rat deterrent” is a professional pest-management system: secure waste, close bin lids, keep bins away from walls, clean spills immediately, store food off the floor, check stock damage, repair doors and gaps, inspect drains, monitor activity, train staff to report signs and keep pest-control records.
Do rats hate clean properties?
Rats do not “hate” clean properties, but clean, well-maintained properties give them fewer reasons to stay. A clean property can still have rats if there is a drain fault, broken air brick, wall gap, loft access point or neighbouring source.
This is why clients should not feel embarrassed. Rats are often a building-access issue, not simply a cleaning issue. A spotless kitchen will not stop rats if they are entering through a broken drain. A tidy garden will not stop rats if bird food is spilled every day. A cat will not stop rats if bins are open and the basement has holes. Peppermint oil will not stop rats if a pipe route leads into a warm void.
What to do in the first 24 hours if you see a rat
- Take a photo or video if safe.
- Note the exact location and time.
- Do not handle droppings or dead rats bare-handed.
- Remove accessible food and waste.
- Check bins, drains, manholes, doors and pipe gaps.
- Do not rely on scents, gadgets or online myths.
- Do not use traps or poison unless you understand the legal and safety requirements.
- If you rent, report the issue in writing.
- Call a professional if rats are indoors, repeated, or linked to drains.

What Bon Accord Pest Control does differently
Bon Accord Pest Control does not rely on gimmicks or temporary scare tactics. For rat problems in London, the focus should be inspection, identifying entry routes, checking food and waste sources, checking drains and manholes, checking proofing defects, safe treatment where appropriate, follow-up visits, proofing advice, landlord/property manager recommendations, rat blocker advice where drains are involved, and prevention to reduce recurrence.
This is especially important for London flats, terraced houses, restaurants, hotels, basements, commercial kitchens, managed blocks, offices, shops, mixed-use buildings and properties with repeated rat sightings.

Are all rats scared of humans?
Not all rats are scared of humans, but many of them are naturally cautious and fearful of us. Rats have a well-developed sense of smell and hearing, which allows them to detect human presence from a distance. This makes them wary of approaching areas where humans are present, particularly if they have had negative experiences in the past, such as being chased or threatened. However, rats that have become accustomed to living in close proximity to humans, such as those in cities, may not be as easily scared off and may even become accustomed to being around people. It’s important to note that while some rats may be scared of humans, they can still pose a significant health risk and should be dealt with using appropriate pest control methods.What smells are rats afraid of? Are different scents effective against rats?
There are certain smells that rats are believed to be afraid of, although scientific evidence supporting the effectiveness of these scents as a rat deterrent is limited. Some commonly suggested rat-repellent scents include peppermint oil, ammonia, garlic, and mothballs. These scents are believed to be effective because rats have a highly developed sense of smell and are sensitive to strong odors. However, it’s important to note that different rats may react differently to different scents, and some rats may even become habituated to certain smells over time, making them less effective as a long-term deterrent. Additionally, while these scents may help to deter rats from entering an area, they are unlikely to eliminate an existing infestation and should be used in combination with other pest control methods.Do rats fear any smells?
There is limited scientific evidence to support the effectiveness of certain scents as rat deterrents. While some scents like peppermint oil, ammonia, garlic, and mothballs are believed to be unpleasant to rats, their effectiveness as long-term rat deterrents is uncertain, and different rats may have different reactions to different smells. It’s best to use other pest control methods in combination with scents to deter rats.Should people be scared of rats?
People should be cautious around rats because they can carry diseases that can be transmitted to humans. Rats are known to carry a number of diseases, including Hantavirus, Leptospirosis, and Salmonellosis. These diseases can be transmitted to humans through contact with rat droppings, urine, or saliva, or through bites or scratches from infected rats. In addition to disease transmission, rats can also cause damage to property and structures by chewing through wiring and insulation. However, it’s important to note that not all rats carry diseases, and many rat populations are not a direct threat to humans. In fact, most rats are more afraid of humans than humans are of them and will usually try to avoid contact with people. In general, people should take basic precautions to prevent contact with rats, such as keeping food in sealed containers, sealing up any potential entry points in homes or buildings, and avoiding areas where rats are known to be present. Overall, while rats can pose a potential health threat to humans, it’s important to approach the issue with a balanced perspective and take appropriate measures to control rat populations and minimize the risk of disease transmission.Should I be scared of a rat in my house?
While encountering a rat in your house can be alarming, it’s important to approach the situation calmly and assess the level of risk. In general, rats are more afraid of humans than humans are of them and will usually try to avoid contact with people. However, rats can carry diseases that can be transmitted to humans through contact with their droppings, urine, or saliva. According to the Centers for Disease Control and Prevention (CDC), Hantavirus Pulmonary Syndrome (HPS) is a rare but serious disease that can be transmitted to humans through exposure to infected rat droppings, urine, or saliva. It’s important to take appropriate precautions if you encounter a rat in your home, such as wearing gloves and a mask when cleaning up any rat droppings and sealing up any potential entry points to prevent future infestations. If you are concerned about the presence of rats in your home, you should contact a professional pest control service to assess the situation and provide guidance on appropriate control measures.Will light keep rats away?
Light alone is not an effective method to keep rats away. Rats are nocturnal animals and are active mainly at night when it is dark. While bright lights may temporarily startle rats, they are unlikely to provide a long-term deterrent. In fact, some studies have suggested that rats may actually be attracted to well-lit areas as they may provide better visibility and safety from predators. Therefore, relying solely on light as a rat deterrent is not recommended. It’s best to use other methods such as sealing potential entry points, removing sources of food and water, and using traps or poison as appropriate.Why do rats scare us?
Rats can be scary to some people because they are associated with disease and filth. Rats are known carriers of various diseases that can be transmitted to humans, including Hantavirus Pulmonary Syndrome, Leptospirosis, Rat-bite Fever, Salmonellosis, and Tularemia. These diseases can be transmitted to humans through contact with rat droppings, urine, or saliva, or through bites or scratches from infected rats. In addition to directly transmitting disease, rats can also harbor other parasites and disease-carrying insects such as mites and fleas. These insects can then bite humans and transmit diseases such as Plague, Murine Typhus, and Rickettsialpox. The fear of rats may also be influenced by cultural and societal factors, such as negative portrayals of rats in media and literature. Some people may also have a phobia of rats, which is an intense and irrational fear of these animals that can interfere with daily life. Overall, the fear of rats is largely based on their potential to spread disease and their association with unsanitary environments. It’s important to take appropriate precautions when dealing with rats, such as wearing gloves and a mask when cleaning up any rat droppings and sealing up any potential entry points to prevent future infestations. If you are concerned about the presence of rats in your home, you should contact a professional pest control service to assess the situation and provide guidance on appropriate control measures.Are rats scared of humans?
Rats are not typically scared of humans and can even approach them for food or shelter. However, they can also learn to avoid humans if they perceive them as a threat. It’s important to remove rats from human living spaces to prevent health risks and property damage.Are rats scared of cats?
Rats have a natural fear of predators, and cats are one of their primary predators in the wild. As a result, rats may be scared of cats and try to avoid areas where they are present. However, rats are also known to be adaptable, and in some cases, they may learn to avoid cats or live alongside them without fear. It’s worth noting that having a cat in a household is not always an effective method for rat control, as rats can be cautious and may find ways to avoid or outsmart their feline predators. Effective rat control often requires a comprehensive approach that includes professional pest control services, sealing entry points, and maintaining a clean environment.Are rats scared of dogs ?
Rats have a natural fear of predators, and dogs are one of their primary predators in the wild. As a result, rats may be scared of dogs and try to avoid areas where they are present. However, rats are also known to be adaptable, and in some cases, they may learn to avoid dogs or live alongside them without fear. Having a dog in a household can sometimes help to deter rats, as the presence of a dog and its scent may make rats feel unsafe and avoid the area. However, it’s important to remember that rats can carry diseases and pose a health risk to both dogs and humans. Effective rat control often requires a comprehensive approach that includes professional pest control services, sealing entry points, and maintaining a clean environment.Smells to deter rats?
There are several smells that are known to deter rats, which can be useful as a natural and non-toxic method of rat control. Here are some examples:- Peppermint oil: Rats have a strong sense of smell and are repelled by the strong scent of peppermint oil. Place cotton balls soaked in peppermint oil in areas where rats are likely to be present.
- Eucalyptus oil: Similar to peppermint oil, eucalyptus oil has a strong scent that rats find unpleasant. Place cotton balls soaked in eucalyptus oil in areas where rats are active.
- Ammonia: Rats are known to avoid strong smells, and the strong odor of ammonia can deter them. Place a small bowl of ammonia in areas where rats are active, but be sure to keep it out of reach of children and pets.
- Garlic: The strong scent of garlic can also repel rats. Crush a few cloves of garlic and place them in areas where rats are active.
- Apple cider vinegar: The strong scent of apple cider vinegar can also deter rats. Mix equal parts apple cider vinegar and water and place in a spray bottle. Spray the solution in areas where rats are active.
