Nobody wants to discover they've got rats at home.

Whether you've heard scratching in the loft late at night, found droppings in the garage or caught sight of something disappearing behind the shed, it's enough to make most people wonder how bad the problem really is. The good news is that most rat problems can be sorted, especially if you act quickly. The key isn't just getting rid of the rats — it's stopping them coming back. This guide explains how to spot the signs of rats, what to do first, which methods actually work, and when it's time to call a professional pest controller.

Is finding a rat in your house an emergency?

Not every rat sighting is an emergency, but it is something you should deal with sooner rather than later.

If you've seen one rat indoors, there's a good chance there are others nearby. Rats breed quickly and are experts at finding hidden places to nest, particularly in lofts, cavity walls, garages and beneath floorboards.

You should contact a pest controller promptly if:

• You've seen a rat inside your living space

• You keep finding fresh droppings

• You can hear scratching in walls or ceilings at night

• Rats have chewed electrical cables

• You have vulnerable family members or pets at home

If you've only spotted rats in the garden, the situation is usually less urgent, although it's still worth dealing with before they decide your house looks inviting too.

First steps: what to do if you think you have rats

Before you rush out to buy traps or poison, spend a little time working out why they're there in the first place.

In many cases, removing food sources and sealing entry points is just as important as getting rid of the rats themselves.

Start by:

• Looking for obvious entry points around your home

• Clearing away accessible food sources

• Keeping pet food sealed overnight

• Emptying bins regularly

• Tidying clutter where rats could hide or nest

• Taking photos if you've spotted droppings or damage

Emergency rat removal

If you've got a rat running around inside your home, it's understandable to want it gone as quickly as possible.

A private pest controller can usually attend much faster than waiting for local authority services, particularly if the rat is inside your living space.

Until help arrives:

• Keep children and pets away from the area

• Close internal doors where possible

• Block obvious escape routes with towels if it's safe to do so

• Avoid cornering or handling the rat yourself

Most people are far better off leaving the capture to someone who deals with situations like this every day.

How do rats get into your home?

One of the reasons rats are so successful is that they don't need much space to get inside.

Common entry points for rats include:

• Damaged air bricks

• Gaps around pipes

• Broken drain covers

• Holes around utility cables

• Worn garage doors

• Gaps beneath external doors

• Cracks in brickwork

• Open vents

Older homes often have more potential access points, but newer properties aren't immune either. If food, warmth and shelter are available, rats are remarkably persistent.

The signs of rats in your house

You don't always see the rats themselves. Most people first realise something's wrong because they notice one or two small clues that gradually start adding up.

Rat droppings

Rat droppings are usually dark brown or black and shaped a little like large grains of rice.

Fresh droppings look shiny, while older droppings become dull and crumbly.

Finding several droppings in the same place often suggests regular rat activity.

Scratching noises

One of the most common signs of rats in the home is scratching or scurrying sounds after dark.

You might hear them:

• In the loft

• Behind plasterboard

• Under floorboards

• Inside kitchen cupboards

• Beneath decking

Because rats are mostly nocturnal, the noises often become much more noticeable at night when the house is quiet.

Gnaw marks

Rats constantly chew to keep their teeth from becoming overgrown.

You might notice gnaw marks on:

• Timber

• Plastic pipework

• Food packaging

• Loft storage boxes

• Electrical cables

Chewed electrical wiring should always be treated seriously because damaged cables can become a fire risk.

Nests

Rats build nests anywhere that's warm, dry and undisturbed.

Common nesting places include:

• Loft insulation

• Cavity walls

• Garages

• Behind kitchen units

• Garden sheds

They often use shredded cardboard, paper, insulation or fabric to build their nests.

Smears and footprints

As rats repeatedly use the same routes, they leave greasy smudge marks along skirting boards and walls.

In dusty lofts or garages, you may also notice tiny footprints or tail marks.

Why rats are more than just a nuisance

Apart from the obvious unpleasantness, rats can cause genuine damage to your home.

They can:

• Contaminate food with urine and droppings

• Damage insulation and stored belongings

• Chew plumbing and electrical wiring

• Spread bacteria and disease

• Introduce parasites such as fleas and mites

This is why it's worth acting quickly, even if you've only seen occasional signs.

A small problem is usually much easier (and cheaper) to deal with than a well-established infestation.

How to get rid of rats

Once you've dealt with the things attracting rats to your home, it's time to deal with the rats themselves.

There are several ways to do this, but not all are equally effective. The right approach depends on how serious the infestation is and whether the rats are inside your home or outside in the garden.

Rat traps

For smaller infestations, traps are often the quickest and safest option.

Snap traps remain one of the most effective methods because they deal with the problem immediately and allow you to see whether you've caught anything.

If you're using traps yourself:

• Place them where you've seen signs of rat activity

• Position them against walls, as rats prefer to travel along edges

• Use several traps rather than relying on just one

• Check them regularly

Good bait options include:

• Peanut butter

• Chocolate spread

• Dried fruit

• Nuts

• Breakfast cereal

Should you use rat poison?

Rat poison is available to buy, but it's not always the best solution.

If it's used incorrectly, poisoned rats can die in inaccessible places such as cavity walls or beneath floorboards, leaving you with unpleasant smells that can linger for weeks.

Poisons can also pose risks to children, pets and wildlife if they're not used exactly as directed.

For larger infestations, it's usually safer to let a professional pest controller decide whether poison is appropriate and where it should be placed.

How not to get rid of rats

If you've been searching online, you've probably come across dozens of supposed 'miracle' rat deterrents.

The problem is that very few of them solve an established infestation.

Peppermint oil

Peppermint oil has a strong smell and may discourage rats for a short time.

However, there's little evidence that it will persuade established rats to leave your home altogether.

Garlic

Garlic is another popular suggestion.

While rats may initially avoid strong smells, they quickly become accustomed to them if food and shelter are still available.

Mothballs

Mothballs are sometimes recommended because they contain naphthalene.

Unfortunately, the concentration isn't high enough to deal with an existing rat infestation safely or effectively.

Ultrasonic devices

Ultrasonic pest repellents continue to divide opinion.

Some people report short-term success, but current evidence suggests rats quickly become accustomed to the sound and carry on as normal.

Cats and dogs

A good mouser might occasionally catch a rat, but pets rarely eliminate an established rat population on their own.

In fact, it's usually the rats that adapt their behaviour rather than disappear altogether.

How to get rid of rats without poison

If you'd rather avoid poison altogether, there are still plenty of options.

Depending on the situation, you could try:

• Snap traps

• Live-capture traps (where appropriate)

• Blocking access points

• Removing food sources

• Improving storage and housekeeping

• Professional pest control using integrated pest management techniques

For most homeowners, preventing rats from returning is just as important as removing the ones already there.

How to get rid of rats in your garden

Seeing rats outside doesn't automatically mean they'll move indoors, but it's often a warning sign that something in your garden is attracting them.

There are a few simple ways to make your garden less inviting to rodents.

Keep the garden tidy

Long grass, piles of timber and general clutter provide excellent shelter.

Keeping your garden well maintained removes many of the hiding places rats look for.

Be careful with bird feeders

Bird food is one of the biggest attractions for rats. If seed regularly falls onto the ground, you're effectively providing a free meal.

Consider:

• Using catch trays beneath feeders

• Sweeping up fallen seed regularly

• Feeding little and often

Remove standing water

Rats need water as well as food.

Repair dripping outdoor taps and avoid leaving containers of standing water where possible.

Seal sheds and outbuildings

Check garden buildings for holes or gaps that could provide shelter.

Blocking access early is much easier than dealing with a family of rats later.

Check beneath decking

The space beneath decking is one of the most common nesting locations.

If rats are getting underneath, consider installing suitable barriers to prevent access.

Manage compost carefully

Compost heaps can attract rats, particularly if they contain cooked food or large amounts of kitchen waste.

Try to:

• Keep compost moist

• Turn it regularly

• Avoid adding meat, dairy or cooked food

How much does rat removal cost?

The cost of professional rat removal depends on how serious the infestation is, how easy the rats are to access and whether more than one visit is needed.

As a general guide rat removal typically costs between £120 and £240 in total.

Many pest controllers include an initial inspection and will often return to check traps or bait stations as part of the service.

If the infestation is well established, or rats have caused damage to insulation, wiring or pipework, you may need additional repair work once the pests have been removed.

When is it worth calling a pest controller?

While it's possible to deal with the occasional rat yourself, professional help is often the quickest and most reliable solution.

It's particularly worth calling a pest controller if:

• You've seen rats inside your home

• The problem keeps coming back

• You can't identify where they're getting in

• You suspect there's a nest in the loft, walls or beneath the floor

• You're uncomfortable using traps or poison yourself

A professional won't simply remove the rats. They'll usually identify how they're getting in, advise you how to stop it happening again and recommend any repairs needed to make your home less attractive to rodents.

FAQs

How do I know if I have rats in my house?

The most common signs include droppings, scratching noises in walls or lofts, gnaw marks, greasy smears along skirting boards and nests made from shredded materials. Many people hear rats before they ever see one.

Will rats leave on their own?

Unfortunately, it's unlikely. If rats have found reliable food, water and shelter, they'll usually stay until those conditions change. In many cases, the population will continue to grow unless it's dealt with.

Do ultrasonic rat repellents work?

Ultrasonic devices may discourage rats for a short time, but there's currently little evidence that they provide a long-term solution once rats have settled into a property. They're generally best viewed as a possible deterrent rather than a cure.

Does peppermint oil get rid of rats?

Peppermint oil may temporarily discourage rats because of its strong smell, but it won't usually solve an established infestation on its own. If rats have already made themselves at home, you'll normally need more effective control measures.

What's the best bait for a rat trap?

Peanut butter is one of the most popular baits because of its strong smell and sticky texture. Chocolate spread, dried fruit, nuts and breakfast cereal can also work well.

How do I know the rats have gone?

You'll usually notice fewer or no fresh droppings, no scratching noises at night and no new signs of gnawing or damage. If traps remain untouched and there's no fresh activity for several weeks, it's a good sign the infestation has been dealt with.

Can rats damage electrical wiring?

Yes. Rats regularly chew electrical cables to keep their teeth worn down. Damaged wiring can become a fire hazard, so if you suspect rats have been chewing cables, it's worth having the wiring checked by a qualified electrician.

Should I call a pest controller or try to deal with rats myself?

For a single rat in the garden, simple preventative measures may be enough. But if you've found rats inside your home, keep seeing fresh signs or suspect a nest, calling a professional pest controller is usually the quickest, safest and most effective option.
