A dead animal in a wall or under the deck is a smell, a health question, and a find-it problem all at once. Here's why it's usually worth not doing this one yourself.
Dead-animal calls are some of the least glamorous work we do and some of the most appreciated. An animal that dies in a wall cavity, under a deck, in an attic, or out on the property after a cold snap — a raccoon, an opossum, an iguana, whatever it is — turns into a smell that fills a house, a health question, and a where-is-it puzzle all at once. It's the job people are most relieved to hand off.
This isn't medical advice, and if anyone in the household has a health concern about exposure, talk to a doctor. What follows is why this particular chore is usually worth a call rather than a Saturday.
Finding it is half the battle
The smell tells you there's a dead animal; it doesn't tell you where. Carcasses end up in wall cavities, above ceilings, deep under decks, and in attic corners — places that mean opening up drywall or crawling into tight, contaminated spaces to locate the source. Guessing wrong means cutting a hole in the wrong wall. Tracking a smell to its actual source, sometimes by following the flies or the staining, is a skill, and it's the part owners most often can't crack on their own.
The health and mess side
A carcass is a biohazard, not just an odor. It leaks, it draws flies and maggots, and there's a salmonella and general-pathogen angle to handling any dead animal — iguana carcasses and droppings included — bare-handed. Proper removal means gloves, correct disposal, and cleaning and treating the spot where it lay, not just bagging the body and moving on. The residue left behind is what keeps the smell around if it's done halfway.
- Leaking fluids and staining that need cleaning and treating, not just wiping.
- Flies and maggots that spread from the carcass if it sits.
- Salmonella and other pathogen risk from handling any dead animal, iguanas included, without gloves.
- Lingering odor if the source and residue aren't fully removed.
The cold-snap spike
In Palm Beach County there's a predictable surge in dead-animal calls after a hard cold snap, when cold-stunned iguanas that didn't make it turn up on pool decks, docks, and lawns. A carcass or a pile of droppings under a favorite basking tree isn't something you want sitting on a deck, and it's not something to grab bare-handed given the salmonella angle. The morning after a freeze is one of our busier stretches for exactly this cleanup.
Why the call is usually worth it
Between locating a hidden carcass, handling a biohazard safely, disposing of it correctly, and treating the spot so the smell actually leaves, dead-animal removal has more moving parts than it looks. Add that it's often in a wall or a crawlspace you'd rather not open, and it's the kind of job where a call saves an unpleasant afternoon and a lingering problem. It also pairs naturally with figuring out how the animal got in — because a dead one in the wall usually means the entry point that let it in is still open.
Questions we hear
Why can't I just find and remove it myself?
You can try, but locating a carcass in a wall, ceiling, or crawlspace is the hard part — the smell tells you it's there, not where, and guessing wrong means opening the wrong wall. Add the biohazard side — leaking fluids, flies, and a salmonella risk from handling any dead animal bare-handed — and it's a job most people are glad to hand off.
Is a dead animal a health risk?
It can be. A carcass draws flies and maggots and there's a salmonella and general-pathogen angle to handling any dead animal, iguanas included, without gloves. Proper removal includes cleaning and treating the spot, not just taking the body away. This isn't medical advice — for any exposure concern, talk to a doctor.
Why do I get a dead iguana after a cold night?
Cold snaps stun iguanas, and the ones that don't recover turn up on decks, docks, and lawns the next morning — the morning after a freeze is one of the busiest stretches for these calls. Don't handle the carcass or droppings bare-handed given the salmonella risk; it's a quick, gloved cleanup for a pro.
