And if you need a rat catcher right now? I can be at your door within the hour. But let us get you sorted first.


Emergency Rat Proofing: Minutes 0 to 5 — Work Out What You Are Dealing With
First things first. Are you definitely dealing with a rat and not a mouse? It matters because rats are bigger, cause more damage, and need a different approach.
Here is how to tell the difference:
Rat Signs
- Droppings that are dark brown and about the size of an olive pit (roughly 10 to 14mm long)
- Big gnaw marks on wood, plastic, or cables — the teeth marks will be wider than a pencil tip
- Scratching sounds coming from inside the walls, above the ceiling, or under the floor
- Dark greasy smudge marks along walls and around pipes — rats follow the same paths over and over and their oily fur leaves marks
- A strong musty smell — almost like ammonia — especially in enclosed spaces
If you are ticking off two or more of those, you have got rats. The British Pest Control Association has a helpful guide on identifying different types of rodent activity if you want to double check.
Minutes 5 to 15: Lock Things Down
You do not need to go full action hero. You do not need to chase it, trap it, or start ripping up the floorboards. Right now the goal is simple: make your home less inviting and keep the rat contained.
Put Your Food Away
Rats are in your house for one main reason: food. So get rid of the easy pickings.
- Seal up anything that is open — cereal boxes, bread, biscuits, fruit bowls — put it all in sealed containers or shove it in the fridge
- Wipe down your kitchen surfaces
- Take the bin outside if it does not have a proper sealed lid
- Pick up pet food bowls from the floor
This will not fix the problem but it takes away the reason the rat keeps coming back to your kitchen tonight.
Close Your Doors
If you know roughly which room the rat is in, shut the door. If there is a gap under the door, stuff a rolled-up towel along the bottom. Rats can squeeze through a gap about the width of a two pound coin — seriously — so do not underestimate them. The NHS page on pest infestations explains more about the health risks that make fast containment so important.
Do NOT Try to Catch It Yourself
I know. Every instinct in your body is telling you to deal with this thing right now. But here is the truth:
- Cornered rats can jump up to a metre in the air
- They bite — and it hurts
- They carry nasty diseases like leptospirosis, salmonella, and hantavirus
Just leave it alone. Shut the door. Let a professional handle it. If you are searching for emergency rat removal or a rat catcher in Prescot, save yourself the stress and the trip to A&E and call someone who does this for a living.


Minutes 15 to 30: Get the Evidence
This bit might sound weird but it is genuinely one of the most useful things you can do before your pest controller arrives. Grab your phone and start taking photos and making notes.
What to Photograph and Write Down
- Where you heard the noise — be specific. Which room? Which wall? Was it above you or below you?
- Any droppings — take a photo with a coin next to them so you can show the size
- Any damage — chewed wires, holes in walls, torn-up insulation, scratched wood
- Any gaps or holes you can see — around pipes, along the bottom of walls, near the roofline, around cables coming into the house
- Any greasy smear marks — usually along walls or on beams
- Anything weird near your outside drains — cracked drain covers, holes in the ground near drain runs, or displaced manhole lids
Why does this matter? Because when I turn up for an emergency rat proofing job, your photos and observations save me a huge amount of time. You live in the house. You know what looks wrong. That information is incredibly helpful. Check out our guide on how to prepare for a pest control visit for more tips on what to have ready.


Emergency Rat Proofing: Understanding How They Got In (Minutes 30 to 45)
This is the part most people do not think about — and it is the part that actually matters the most.
Here is the thing: killing a rat is easy. Working out how it got into your house and blocking that route is the real skill. If you do not do that, more will follow. Guaranteed.
So let us talk about the most common ways rats get into homes — especially the types of homes we have across the North West.
How Do Rats Get Into Victorian Terrace Walls?
This is one of the most common questions I get asked, and it is a big deal around Rainhill, St Helens, Prescot, and across Merseyside because so many of our homes are Victorian or Edwardian terraces.
These older houses were built with cavity walls that have no barriers inside them. Think of the wall cavity like an empty vertical tunnel running from the ground floor all the way up to the loft. If a rat gets into that cavity at ground level — through a crumbling bit of mortar, a broken airbrick, or a gap around a gas pipe — it can climb all the way up inside the wall to your loft space without hitting a single obstacle.
That is why you sometimes hear scratching that seems to travel upwards — from downstairs to the bedroom wall to the loft. The rat is literally climbing inside your wall.
Rat proofing Victorian terrace cavity walls is one of the most common and most important jobs I do. It takes proper materials and proper knowledge of how these old houses were built. You can read more about common construction issues in older properties on the Heritage Foundation website.


Lofts and Rooflines
Rats get into lofts through:
- Gaps where the roof meets the soffit boards (the boards that run along the underside of the roof overhang)
- Missing or cracked roof tiles
- Gaps around the chimney stack where the lead flashing has lifted
Identifying rat entry points in lofts and crawlspaces means getting up there on your hands and knees and knowing what to look for — droppings along the joists, gnaw marks on the timber, or small holes chewed through the roofing felt. We have a more detailed post on common loft entry points for rats if you want to learn more.


Drains — The Big One
This is the entry point that surprises most people. A huge number of rat problems in the North West start underground in the drainage system.
Here is what happens: the pipes under your house crack, a joint shifts, or a section collapses. Suddenly there is an open gap between the sewer and the soil beneath your house. Rats come up through the broken pipe, dig through the earth, and pop up into your subfloor void — the empty space between the ground and your floorboards.
This is exactly why I recommend a CCTV drain survey for rats on most jobs. It involves feeding a small camera through your drains to check for damage. Until you know the state of your drains, you are just guessing where the rats are coming from. Water UK has useful background information on how public sewer systems connect to domestic properties if you want to understand the bigger picture.


Your Neighbours
If you live in a terrace, this one is unavoidable. Rats do not care about property boundaries. If next door has a problem, the rats can travel through shared loft spaces, through the party wall (the wall between your houses), and through connected drainage systems.
This is a massive issue across the older streets in St Helens and Prescot where entire rows of houses share continuous roof spaces and interconnected drains.
Minutes 45 to 60: Call Someone Who Knows What They Are Doing
You have locked down the house. You documented everything. And have a rough idea of how the problem might have started. Now it is time to get a professional in.
If you are searching for “who is the best local rat catcher near me“ right now, here is what to look for:
They actually turn up quickly.
If you are dealing with an emergency, you need pest control within the hour — not a vague booking for next week. If you are within a 10-mile radius of Rainhill, I will be there the same day, usually within the hour. That is how emergency pest removal in Merseyside should be handled.
They inspect before they do anything else.
Anyone who starts chucking poison around before they have worked out how the rats are getting in is doing it wrong. A proper pest controller will inspect your loft, your subfloor, your exterior walls, and your drains before they touch anything.
They block the entry points — not just poison the rats.
This is the difference between a temporary fix and a permanent solution. Rat proofing for emergencies means physically sealing every entry point with materials rats cannot chew through — galvanised steel mesh, metal plates, cement-based fillers, and specialist one-way drain valves. Poison on its own just kills the rats that are already inside. It does nothing to stop the next ones coming in. Read more about our rat proofing methods to understand what proper proofing looks like.
They know the local houses.
A local North West pest expert understands how the houses in this area were built — the cavity wall details, the drainage layouts, the common weak points in Victorian, Edwardian, and post-war properties. You cannot learn this stuff from a manual. You learn it by crawling through hundreds of lofts and subfloors across these specific streets over years.
They tell you what it costs upfront.
“How much does emergency pest control cost in the North West?” is a completely fair question and you should get a straight answer. A decent pest controller will give you a clear quote after the initial inspection — no hidden fees, no pressure tactics, no nasty surprises on the invoice.

Your Questions Answered
“What to do if I find a rat in my house?”
Follow the steps in this guide: confirm what you are dealing with, put your food away, close your doors, take photos of the evidence, and call a local professional. Do not try to catch it yourself.
“How do rats get into Victorian terrace walls?”
Through gaps in the mortar, broken airbricks, holes around pipes, and from damaged drains into the subfloor. Once they are inside the wall cavity, they can climb all the way up to the loft because these old walls have no internal barriers. Read more on our page about rat proofing Victorian terrace cavity walls.
“How much does emergency pest control cost in the North West?”
It depends on how bad the problem is and how much proofing work is needed. I always give a clear and honest quote after the initial inspection. No call-out fees within my service area and no hidden charges. See our pricing page for more details.

“Do I need a CCTV drain survey?”
If there is any chance the rats are coming in through the drains — and around here there usually is — then yes. A CCTV drain survey for rats is the only way to see what is going on underground. It can save you months of chasing a problem you will never fix without it. The NADC (National Association of Drainage Contractors) has more information on what drain surveys involve if you want to read up before booking.
Do Not Leave It Until Tomorrow
Here is the reality and I am not saying this to scare you. I am saying it because it is true.
Rats do not take a night off. Every hour you wait is another hour they spend gnawing through your electrical wires (which is a fire risk — Electrical Safety First highlights rodent damage as a common cause of house fires), contaminating your kitchen surfaces with bacteria, and working out new routes deeper into your home. One rat becomes two. Two become ten. The longer you leave it, the worse it gets and the more it costs to fix.
You have already done the hardest part — you have admitted there is a problem. Now let someone sort it.
