Dead Animal Removal London
Discreet, Professional Carcass Removal & Odour Treatment
A dead animal in a wall, under a floor or in a loft space creates an immediate and serious environmental health problem. The decomposition process releases ammonia, hydrogen sulphide and other toxic gases, attracts blowflies, secondary pests (dermestid beetles, phorid flies) and creates an overwhelming, persistent odour that permeates the entire property. Without professional removal and disinfection, the odour can last for weeks or months. Zeus Services provides fast, discreet dead animal removal across London with same-day response, including full odour neutralisation and disinfection.

What's Included
Every treatment is carried out by a certified technician and includes:
How We Treat It
Our step-by-step treatment process, used by every Zeus technician on every visit.
Location
We use specialist equipment including thermal imaging cameras and probe tools to locate the carcass precisely within wall cavities, floor voids and loft spaces — minimising the amount of access work required.
Access & Removal
The technician creates the minimum necessary access point to retrieve the carcass. Where possible we work through existing voids and service routes. The carcass is removed and disposed of safely in accordance with Environmental Protection Act regulations.
Disinfection & Odour Treatment
The affected area is treated with hospital-grade EN14476-certified disinfectant, killing all bacteria and viruses from the decomposition process. Specialist odour neutralisers are applied — not masking agents — to permanently eliminate the smell at the molecular level.
Secondary Pest Treatment
We treat the surrounding area for secondary pests — blowfly larvae (maggots), phorid flies, dermestid beetles and other species attracted by the decomposition. Without treating secondary pests, infestations will persist after the carcass is removed.
Frequently Asked Questions
How do I know there is a dead animal in my wall or floor?
Key signs include an intense, unmistakable sweet-sour odour of decay that worsens over 3–7 days, clusters of blowflies or phorid flies (small hump-backed flies) emerging from a specific area, and in some cases visible staining on walls or ceilings from decomposition fluids.
How long does the smell last after removal?
Without professional odour treatment, residual smell from contaminated surfaces and fluids can persist for several weeks. With our professional odour neutralisation treatment, the smell is eliminated at the molecular level — not masked — and the area is safe immediately after treatment.
Will you need to open my wall or floor?
We use thermal imaging to locate the carcass precisely before any access work begins, minimising disruption. In many cases the carcass can be retrieved through existing access points. Where wall or floor opening is required, we create the smallest possible access point.
Is it safe to remain in the property?
The decomposition gases (ammonia, hydrogen sulphide) can cause respiratory irritation and the secondary pests carry disease. We recommend minimising time in the affected area until the carcass is removed and disinfection is complete. We will advise on specific precautions when we attend.
Can you remove dead animals from loft spaces and under floors?
Yes — these are our most common removal scenarios. Rats and mice often die in loft insulation, wall cavities and under suspended timber floors after consuming rodenticide. We have the equipment and experience to retrieve carcasses from confined and difficult access areas.
