Service overview
Rats in Walls Removal in Melbourne Explained
Rats in Walls Removal in Melbourne is a targeted pest control service that locates rodents living inside wall cavities, removes them, seals their entry points, and sanitises the space. We use inspection mirrors, thermal imaging cameras and tracking powder to map exactly where rats are moving before we place a single snap trap or bait station. It is not guesswork. Every cavity has a route in and a route out, and we find both.
Melbourne's older housing stock is the problem. Weatherboard homes in Hawthorn and solid-brick terraces in South Yarra have wall cavities that run floor to ceiling, giving rats a warm highway between rooms. Once winter rain pushes them in, a single pair can turn into a colony inside six weeks. If you search for wall rat removal near me Melbourne and want it sorted properly, we handle the removal, the proofing and the mess.
- No More Night Noise — Scratching behind the plaster stops once the cavity is cleared. We remove every rat we can access, then seal the entry points so nothing moves back in. Most Melbourne customers report silence within 48 hours of treatment.
- Wiring Damage Stopped — Rats gnaw through electrical cable insulation, and that is a genuine fire risk. We flag chewed wiring we find during inspection so your electrician can make it safe. Catching it early saves thousands in rewiring.
- Entry Points Sealed — Removal without proofing is a temporary fix. We pack gaps with steel wool and copper mesh, then seal with cement mortar or expanding foam. A 12mm gap is all a young rat needs, so we close everything down to that size.
- Droppings Cleaned Safely — Rat droppings and contaminated insulation get removed using APVMA approved disinfectants and proper PPE. We don't just kill rats and leave the mess for you. The cavity is left clean and the dead rat smell is gone.
- Same-Day Response — Book before midday and we can usually be at your Melbourne property the same afternoon. For urgent cases, our emergency wall rat removal Melbourne service runs 24/7. We know a scratching wall at 3am isn't something you can wait a week on.
- Licensed and Insured — Every technician holds a current public health licence and chemical handling certificate. We're fully insured for work inside your home. Rodenticides are APVMA approved and used strictly according to label directions.
- Removal Plus Proofing — Our rats in wall removal services Melbourne customers get include the proofing, not just the trapping. We seal entry points with steel wool, copper mesh and mortar so the cavity stays empty. That's the difference between a one-off fix and a permanent one.
- Upfront Pricing — You get a clear price before we start, based on cavity size, access and how many rats are present. No surprise charges when the job takes longer than expected. We tell you what it costs and what's included, then we do it.

How Our Melbourne Removal Process Works
Request Assessment
We ask where you're hearing the noise, when it's loudest, and whether you've seen droppings. That tells us whether it's rats in walls or rats in roof, and how many technicians to send. Most Melbourne jobs are booked same-day or next morning.
Full Cavity Inspection
Our licensed technician inspects the wall cavities using inspection mirrors and a thermal imaging camera to find nesting sites and movement paths. We check the roof void, subfloor, and every external gap. This takes 45 to 90 minutes on a typical home.
Removal and Trapping
We place snap traps, live catch traps and bait stations at the points rats are actually using. Rodenticide bait blocks go into lockable stations so pets and kids can't reach them. We check and reset traps until the cavity is clear.
Proofing and Sealing
Once the rats are gone, we seal every entry point with steel wool, copper mesh, wire mesh and cement mortar. We work down to a 12mm gap, because anything wider is an open door. This is the step that stops the problem coming back.
Cleanup and Final Check
We remove droppings, contaminated material and any dead rats, then disinfect the cavity. You get a written summary of what we found, what we sealed and what to watch for. A follow-up check is included if activity continues.

Tools and Methods We Use
Thermal Imaging Camera
Detects body heat inside wall cavities so we can pinpoint nesting sites and movement paths without cutting into plaster.
Inspection Mirrors
Lets us see inside cavities through small access points, so we can confirm activity and locate entry points without major demolition.
Snap Traps and Live Catch Traps
Placed at the exact points rats are moving. Snap traps for quick removal, live catch traps where a non-lethal option is preferred.
Lockable Bait Stations
Tamper-resistant stations that hold rodenticide bait blocks securely, so pets and children can't reach them.
Steel Wool and Copper Mesh
Packed into gaps to block entry points. Rats can't chew through either material, unlike expanding foam on its own.
Sealant Guns and Cement Mortar
Used to seal larger gaps around pipes, cables and eaves after the steel wool and copper mesh are in place.
Tracking Powder
Applied at suspected entry points to confirm rat movement and identify the exact routes they're using.
Integrated Pest Management (IPM)
We follow IPM certification principles: identify the species, remove the activity, exclude the entry points, then monitor. This approach targets the cause, not just the symptom, so the problem doesn't return.
APVMA Approved Rodenticide Use
Every rodenticide we use is APVMA approved and applied strictly according to label directions. Bait blocks go inside lockable stations, never loose in the cavity where pets or kids could reach them.
Work Health and Safety (WHS) Compliance
Wall cavity work involves confined spaces, ladders and chemical handling. We follow WHS compliance on every job, including PPE, safe access and correct chemical storage and disposal.
Proofing to 12mm Standard
A young rat can squeeze through a 12mm gap. We seal every entry point down to that size using steel wool, copper mesh, wire mesh and cement mortar, so there's nothing left to squeeze through.
Where this service helps
When to Book This Service
You're hearing scratching in the wall at night and it's getting louder each week.
We inspect the cavity with thermal imaging, identify how many rats are present and where they're entering, then set traps and bait stations at those points. The noise stops within days, and the entry points are sealed so nothing moves back in.
You've found rat droppings in the kitchen and want the source dealt with before it spreads.
We trace the route from the wall cavity to the kitchen, remove the rats, seal the gaps, and clean up the droppings with APVMA approved disinfectant. The contamination risk is cleared and the rats have no path back into your living space.
There's a dead rat smell in the hallway and you can't find where it's coming from.
We use a thermal imaging camera to locate the carcass inside the cavity, remove it through a minimal access point, and treat the area to eliminate the smell. The smell is gone within a day, and we check the cavity for other activity while we're in there.
You've had rats removed before but they've come back through the same gaps.
We inspect the original entry points, remove the new activity, and proof every gap down to 12mm using steel wool, copper mesh and cement mortar. The cavity stays empty because the entry points are properly sealed, not just baited.
Before and after
What a successful service visit changes.
Hawthorn Weatherboard Cavity Cleared
Before
A family in Hawthorn had been hearing scratching in the bedroom wall for three weeks. Droppings were found in the kitchen. Inspection found a 20mm gap under the eaves where rats were entering, plus chewed wiring insulation inside the cavity.
After
We removed four rats over eight days using snap traps and bait stations, sealed the eave gap with copper mesh and mortar, and cleaned out the droppings. The scratching stopped within 48 hours and hasn't returned.
Maintenance: We recommended checking the eave line each autumn before the wet season, and keeping the garden clear of debris against the house.
South Yarra Terrace Dead Rat Removed
Before
A South Yarra terrace had a strong dead rat smell in the hallway that had been building for five days. The source couldn't be found by the homeowner. We used thermal imaging to locate the carcass inside a shared wall cavity between the hallway and the neighbouring property.
After
The carcass was removed through a small access point, the cavity was treated with APVMA approved disinfectant, and the smell was gone within 24 hours. We also sealed two entry points found during the inspection.
Maintenance: We advised the homeowner to check the subfloor vents quarterly, since that was the likely entry route.
Kew Heritage Home Proofed
Before
A Kew homeowner had rats removed by another company six months earlier, but they had returned through the same gaps. Inspection found the original proofing had used expanding foam only, which rats had chewed straight through.
After
We removed the new activity, then re-proofed every entry point using steel wool and copper mesh packed behind cement mortar. Fourteen gaps were sealed down to 12mm. No activity has been recorded since.
Maintenance: We recommended an annual inspection before winter, and a follow-up check three months after proofing to confirm the seals were holding.

How much does rats in walls removal cost in Melbourne?
Emergency or after-hours callouts add a premium. Proofing and droppings cleanup are quoted separately if the entry points are extensive. You get a fixed price before we start.
How do rats get into walls in Melbourne homes?
Rats enter through gaps as small as 12mm, usually where pipes and cables penetrate the exterior wall, under eaves, or through broken roof tiles. Melbourne's older weatherboard and brick veneer homes have plenty of these. Once inside, they travel the full height of the cavity between rooms.
Is wall cavity rat extermination safe in Melbourne?
Yes, when it's done by a licensed technician using APVMA approved products. We use lockable bait stations so pets and children can't reach the rodenticide, and we follow WHS compliance for confined space work. Traps are placed where they won't be touched. We'll walk you through the setup before we leave.
How long does rats in walls removal take in Melbourne?
The initial inspection and setup takes two to four hours on a typical home. Trapping and monitoring usually runs seven to fourteen days, depending on how many rats are present. Proofing and cleanup add another two to three hours. You'll know the full timeline before we begin.

Rat Removal
General rat removal covers the whole property, not just the walls. If rats are also in the roof or subfloor, we treat it as one job so nothing gets missed between the cavities.

Mice Control
Mice often move in alongside rats, using the same gaps and leaving droppings in the kitchen. We check for mice during every wall cavity job and treat both if needed.
View service
Rats in Roof Removal
Rats in walls usually start in the roof. If we find activity in the ceiling void, we treat both areas together so the colony has nowhere left to run.
View service
Rodent Bait Stations
Lockable bait stations are placed inside the cavity and along external walls. They're tamper-resistant, so pets and kids can't reach the rodenticide bait blocks inside.
