Why You Can't Just Wait It Out
Decomposition, Odor & Health Risks
A dead mouse inside a wall void emits a sharp, sickly-sweet odor for roughly 1–2 weeks. A rat can produce strong odors for 2–3 weeks, and a larger animal — a squirrel, raccoon, or opossum — can stink for 6 weeks or more. In Eugene's damp, mild climate, decomposition is slower than it would be in a dry desert environment, which is why "just waiting it out" rarely works the way homeowners hope.
Beyond the smell, decomposing rodents attract secondary infestations of blow flies, flesh flies, and dermestid (skin) beetles — and the carcass itself can harbor pathogens including Hantavirus, Salmonella, Leptospirosis, and fleas carrying secondary diseases. Removing the source is the only fix.
Don't Cut Open Your Drywall Yourself
Disturbing a decomposed carcass releases aerosolized pathogens and creates a worse mess. Our technicians use full PPE, pinpoint the location with thermal and probe tools, and make the smallest possible access cut — then repair-ready patch where needed.
Where Dead Animals Get Stuck
The Most Common Hiding Spots in Eugene Homes
Wall voids
Rodents poisoned by bait or sealed in during exclusion work often die between studs — typically near plumbing or heat sources they were drawn to.
Attic insulation
Rats and squirrels burrow into batts or blown-in cellulose to die. The carcass and contaminated insulation both need removal.
Crawlspaces
Common in Eugene's older homes — animals enter through damaged vents and die under floor joists, often on or beneath the vapor barrier.
HVAC ducts & chimneys
Birds, squirrels, and small mammals fall into uncapped chimneys or ductwork and become trapped — the odor distributes through your entire HVAC system.
Under decks & sheds
Raccoons, opossums, and feral cats often crawl into low spaces to die. Less interior odor, but flies and scavengers attract more pests.
Garages & storage
Behind shelving, under stored boxes, or inside rarely-opened cabinets — easy to miss until the odor takes over the room.
Our Dead Animal Removal Process
Locate, Remove, Sanitize, Deodorize
Most dead animal calls in Eugene are resolved in a single visit. Our technicians arrive with PPE, thermal cameras, drywall repair kits, and enzymatic deodorizers — so we can complete the job without leaving you to clean up or call another trade.
- Pinpoint location using odor mapping, thermal imaging, and fiber-optic scope
- Minimal-access entry — smallest possible cut to reach the carcass
- Full PPE removal of carcass, contaminated insulation, and nesting material
- Biohazard-safe bagging and off-site disposal in compliance with Oregon regulations
- Enzymatic and oxidizing deodorizer treatment — neutralizes odor at the source, doesn't just mask it
- Surface disinfection of framing, drywall edges, and surrounding insulation
- Patch-ready drywall closure or full repair (carpentry option available)
- Inspection for entry points — paired with exclusion if needed to prevent recurrence
Animals We Remove in the Eugene Area
From Mice to Mid-Size Wildlife
We handle dead-animal removal for all common Eugene-area species: house mice, deer mice, Norway rats, roof rats, tree squirrels, flying squirrels, opossums, raccoons, skunks, feral cats, and trapped birds from chimneys and vents. For large wildlife on roadways or city property, contact Eugene Public Works or Oregon Department of Fish & Wildlife.
Don't Let It Happen Again
Pair Removal with Exclusion
If an animal died inside your home, it got in somehow — and others can follow the same route. We strongly recommend pairing dead animal removal with our structural exclusion service to permanently seal the entry points, and our attic and crawlspace cleanout if insulation contamination is widespread.
