In Condell Park, most dead animal calls trace back to a rat in a wall or ceiling, often after baiting, or a possum caught in the roof. In Inner South West Sydney homes with raised timber floors, the subfloor is another common spot. Here is what to do in the meantime.
Found a dead or injured bat?
Do not touch it, even with gloves. Bats can carry Australian bat lyssavirus. Keep children and pets away and call us. If anyone has been bitten or scratched by a bat, wash the wound thoroughly with soap and water and seek medical attention straight away.
Open the windows
Ventilate the room, and close the door to the rest of the house to stop the smell spreading.
Work out where it is strongest
Check each room, the cupboards, the manhole and the outside vents. Flies gathering on one wall or window are a strong clue.
Do not touch it with bare hands
Dead animals carry bacteria, fleas, mites and maggots. Keep pets and children away.
Do not cut into walls or ceilings yet
Smell travels through cavities, and the animal is often not where the smell seems strongest. Locating it first avoids unnecessary holes.

The sooner it is removed, the less the fluids soak into plaster, timber and insulation.

Where the smell is and what happened beforehand usually tells us what has died and where. Find yours below.
Most often a rat or mouse that died in the cavity after taking bait. The smell peaks after a few days and can last for weeks.
A sudden wave of large flies at the windows, or maggots dropping from a light fitting, means something has died in the roof or wall.
Fluids from a dead possum or rat soaking through the plaster. The insulation above usually needs removing as well.
Cats, possums, rats and sometimes foxes crawl into subfloors to die. Low clearances make them hard to reach without the right gear.
Birds and possums fall into uncapped chimneys and flues and cannot climb out. Do not light the fire to deal with it.
Dead rodents in ceiling tiles, wall voids and stockrooms are common in commercial buildings, and need removing before customers notice.
Not every bad smell is a dead animal. Before anyone cuts into a wall, it helps to rule out the other common causes.
| Dead animal | Drain, gas or damp | |
|---|---|---|
| The smell | Sickly and rotten, and unmistakable once it peaks | Sewer gas smells of rotten eggs; damp smells musty and earthy |
| How it changes | Builds over a few days, then fades over weeks | Stays the same, or comes and goes with the weather and water use |
| Where it is | Strongest at one wall, ceiling or vent | Strongest near drains, floor wastes or wet areas |
| Flies | Blowflies and maggots appear within days | Usually none, or tiny drain flies |
| What came before | Baiting, or scratching noises that suddenly stopped | Plumbing work, heavy rain or a floor waste that has dried out |
| What to do | Have it located and removed | Call a plumber, or your gas supplier if you suspect gas |

Dead animal calls in Inner South West Sydney are usually rats that have taken bait and died in a wall or ceiling, or possums in the roof. We find the animal, remove it and deodorise the area.
Sydney's terraces and semi-detached homes share walls and roof voids, so the source of a smell is sometimes next door. The tight subfloors of older inner-city homes are a common place for rats to die.
When rats and mice move indoors in autumn and winter, households put out bait. Poisoned rodents head for somewhere quiet and dark, which is often a wall cavity or the roof void, and die there days later.
A carcass breaks down much faster in warm, humid air. In a Sydney summer the smell can fill a house within hours, and flies find it almost immediately.
Calls peak in winter and early spring, a few weeks behind the rodent baiting season. Summer calls are fewer but more urgent, because heat makes the smell far stronger.
Waiting for the smell to pass seems easier than finding the source. Here is why it rarely works out that way.
A carcass carries bacteria and attracts fleas, mites and ticks, which leave the body as it cools and move on to pets and people.
Blowflies lay eggs within hours. Maggots follow, then a wave of adult flies through the house a week or two later.
A rat can smell for two to three weeks and a possum for much longer. Odour soaks into insulation, plaster and soft furnishings and lingers after the animal has gone.
Fluids stain ceilings and walls, and the carcass draws ants, cockroaches and other rodents to the same spot.
The goal is simple: find it, remove it, and leave the area clean and smelling normal. Our technicians explain each step and the price before they start.
Found before anything is cut
Smell travels along cavities, so the strongest point in a room is not always where the animal is. We narrow down the location from the roof void, subfloor, vents and wall plates first, and use thermal imaging where it helps, so any opening is as small as possible.
Call and describe the smell
Where it is strongest, when it started and whether there has been baiting or animal noise.
Same day visit
A technician checks the roof void, subfloor and walls to pinpoint the carcass.
Upfront price
You get the price, including any access work, before anything starts. No hidden charges.
Carcass removed
The animal, nesting material and any soiled insulation are bagged and taken away for disposal.
Disinfect, deodorise and proof
The area is treated with disinfectant and an odour neutraliser, and we point out or seal the entry point.
The price depends on where the animal is and how hard it is to reach. A dead rat in an accessible roof void is the quickest job. A possum deep in a double-brick wall, or a carcass under a low subfloor, takes the most work. These are the things that set the price:
Finding it. Location already known, or a smell that needs tracking down.
Access. Open roof void, tight subfloor, wall cavity or chimney.
Opening the structure. Whether plaster, a panel or flooring needs to come out.
Clean-up needed. Soiled insulation, staining and deodorising.
You get an upfront price with no hidden charges after the technician has seen the job. Call 07 3544 9883 or send your details online for a faster estimate.
Dead animal jobs are about finding it quickly and finishing properly. We do not leave until the carcass is out and the area is treated.
Technicians spread across Sydney, so you are not living with the smell for another night.
Our technicians bring years of experience working in the roof voids, wall cavities and subfloors of Sydney homes of every age.
Taking the animal out is half the job. Treating the area is what clears the smell.
The price is agreed before work starts, including any access work. No hidden costs at the end.
A smell in a restaurant, a rental inspection tomorrow or maggots in the lounge room are treated as urgent, any hour.
We look for how the animal got in, so you are not calling again next winter.
*Onsite in 60 minutes applies to urgent jobs and depends on technician availability and location.
It is an unpleasant job in a private part of your home. Here is what you can count on from the moment you call.
You know who is coming. The technician's name and arrival window are sent to you before they leave.
You see what was found. A photo of the animal and where it was, if you want to see it.
You know what will be opened. Any plaster, panel or board we need to remove is explained and agreed first.
You can call us back. If the smell has not cleared after the job, call the same number and we return.
Our technicians cover Condell Park 2200 and the rest of Inner South West Sydney, including Allawah, Arncliffe, Bankstown and Belmore, with same day service and upfront pricing.
A dead mouse may smell for one to two weeks, a rat for two to three weeks and a possum for a month or more, depending on temperature and airflow. Even after that, odour can linger in insulation and plaster. Removing the carcass is the only quick fix.
It depends on whether the location is known, how hard the animal is to reach, whether part of a wall or ceiling has to be opened, and how much clean-up is needed. A technician gives you an upfront price before any work starts, with no hidden costs.
We work from the roof void, subfloor and vents to narrow down which cavity the smell is coming from, look for flies and staining, and use thermal imaging where it helps. Only then is a small opening made, if one is needed at all.
The smell itself is unpleasant rather than dangerous, though it can cause headaches and nausea. The real risks are the bacteria, fleas, mites and flies that come with a carcass, which is why it should not be handled without protection.
If you can see and reach it safely, wear gloves and a mask, double-bag it and disinfect the area. If it is in a wall, a tight roof space or under the house, it is safer and usually quicker to have it done professionally.
Often not. Many carcasses can be reached from the roof void or subfloor. If an opening is needed, the technician shows you where and how big before starting, and keeps it as small as possible.
Usually because it took bait. Poisoned rodents become slow and retreat to their nest in a wall or roof to die. Locked bait stations, traps and proofing reduce the risk of it happening again.
Yes. Dead possums in roofs, walls, chimneys and under houses are among our most common removals. The area is disinfected and deodorised, and we can proof the roof so another possum does not move in.
Yes. We offer same day service across 428 Sydney suburbs, and for urgent jobs a technician can often be onsite in 60 minutes. Our phones are answered 24/7.
We remove any soiled insulation or nesting material, treat the area with disinfectant and apply an odour neutraliser. Most of the smell goes within hours of the carcass leaving the house, and the rest fades over a day or two with ventilation.
